What are the Conext SW Inverter/Charger’s key features?

True Sine Wave output – as an inverter, the Conext SW provides true sine wave power for your microwave, entertainment system, computer, and other loads. This power is identical to the AC source provided from the utility grid (power company). Some of the benefits of high efficiency true sine wave power include consistent cooking in your microwave, handling of sensitive loads such as your TV set, dimmer switches, and appliances with speed controls.
Multiple unit configuration – the Conext SW Inverter/Charger has a highly versatile platform capable of parallel multiple unit configuration1 to increase power levels.
High surge capacity – the Conext SW Inverter/Charger has a surge rating that is twice the maximum continuous output power rating to start difficult loads like well pumps, refrigerators, or A/C compressors. See “Inverter Specifications” on page 6–2.
Power factor correction – Power factor-corrected (PFC) input minimizes AC input current required for charging, increasing AC pass-through capacity.
Multi-stage charging – the Conext SW Inverter/Charger has a high output, multi-stage charging capability that minimizes charging time.
Adjustable frequency – the Conext SW Inverter/Charger is capable of operating from a 50Hz and 60Hz power source by extending the AC qualification frequency range. See “AC Settings” on page 4–24.
Temperature-controlled, variable-speed internal cooling fans – the fans turn on when the internal temperature reaches 113 °F (45 °C) and reaches maximum speed at 158 °F (70 °C). The fan turns off when the internal temperature falls to 104 °F (40 °C).
Xanbus-enabled – the Conext SW Inverter/Charger is also Xanbus-enabled which allows network compatibility and communication with other Xanbus-enabled devices. See more information under “Xanbus System” on page 2–2.

What must batteries be charged correctly for?

For the unit to perform at the highest level, the batteries must be charged correctly. The Conext SW has optimized algorithms for flooded, gel, and AGM batteries.

Why must the charging formula be adjusted according to the actual battery temperature?

Since battery temperature is a key factor in correct charging, the charging formula must be adjusted (automatically and in real time) according to the actual battery temperature to ensure that batteries are fully charged, but not overcharged. For this reason, a battery temperature sensor (BTS) is included with the Conext SW that works with a temperature-compensated charge formula.

What does the Conext SW have the ability to do unlike many other chargers?

The Conext SW—unlike many chargers—has the ability to recharge batteries even if the battery voltage is very low, that is, as low as 12 volts.

What can happen to the cells in a flooded battery over time?

Over a period of time, the cells in a flooded battery can develop uneven chemical states. This can result in a weak (undercharged) cell which, in turn, can reduce the overall capacity of the battery.

What does the Conext SW’s multi-stage charging cycle include?

To improve the life and performance of a non-sealed, flooded battery, the Conext SW’s multi-stage charging cycle includes a manual equalize mode that can be used, if recommended by the battery manufacturer.

What does the Conext SW have that connects the inverter output or AC input from the AC generator to loads?

The Conext SW has a built-in transfer relay that connects your inverter output or AC input from the AC generator to your loads.

What does the Conext SW provide a number of features to facilitate?

Because the usual AC power sources such as small generators often have limited current availability, having the capability to manage your AC loads is extremely valuable. The Conext SW provides a number of features to facilitate this.

What does minimizing the AC current used by the charger mean?

The charger is power factor corrected to use AC current as efficiently as possible. Minimizing the AC current used by the charger means more current is available for your AC loads.

What does the Conext SW have that prioritizes AC loads?

The Conext SW has a power share feature which prioritizes your AC loads by reducing the charge current depending on the load current; and programmed AC breaker setting.

What happens when AC input sources have low voltage?

Occasionally, AC input sources have low voltage. To avoid loading these weak sources any further, the charger automatically reduces its AC current draw as the AC voltage approaches the minimum acceptable level.

What does the Conext SW Inverter/Charger support to increase capacity?

Conext SW Inverter/Charger supports multiple unit configuration to increase capacity. Conext SW multiple unit configuration is limited to one master unit and one slave unit.

What does multiple unit configuration allow?

Multiple unit configuration allows two inverter/chargers to operate in parallel thereby doubling the capacity in inverter mode. The multiple inverters communicate over the Xanbus network and intelligently manage the load balance between the units.

What does a 240V AC input allow?

Requires a 240V AC input. The feature does not work on 120V AC input only.

What are the following topics covered in Chapter 1 of the Owner’s Guide?

In Conext SW Inverter/Chargers, multiple unit configuration (installation) is limited to two units – one master unit and one slave unit.

What is required for the dead battery charging feature to work?

Requires a 240V AC input. The feature does not work on 120V AC input only.

When a single unit transitions from bulk to absorption, does the other unit also transition?

Yes, when a single unit transitions from bulk to absorption, so does the other unit.

In absorption, must the two units complete the absorption stage before transitioning to the next stage?

Yes, in absorption, the two units must complete the absorption stage before transitioning to the next stage.

Do the two units load share when charging?

The two units do not load share when charging except during the bulk stage.

When do the Conext SW units stop sharing charge current?

The Conext SW units stop sharing charge current just before completing the bulk stage.

Do the units share charge current during the absorption and float stages?

No, the units do not share charge current during the absorption and float stages.

How does each unit charge the batteries?

Each unit charges batteries based on the Max Charge Rate setting and active internal (temperature-based) deratings.

If equalization is enabled on one or more devices capable of equalization charging, when is the equalize cycle performed?

If equalization is enabled on one or more devices capable of equalization charging, only those devices perform an equalize cycle after absorption.

If equalization is enabled on one or more devices capable of equalization charging, what do other devices transition to?

Other devices transition to float (if three-stage charging is selected) or transition to AC pass-through (if two-stage charging is selected).

What are the protection features of the Conext SW?

Over temperature shutdown for critical components such as the transformer and the power board
Battery temperature sensor (BTS) failure/battery temperature out-of-range fault protection
DC output over voltage protection during charge mode
AC output overload and short circuit protection during invert mode
AC backfeed1 protection

What does the Battery Temperature Sensor (BTS) provide?

The Battery Temperature Sensor (BTS) provides these protection features:

battery over temperature charging protection preventing battery charging at 140 °F (60 °C) or higher, and
charging voltage compensation based on the temperature of the battery the BTS is connected to.

When does an AC backfeed error occur?

An AC backfeed error occurs when the AC output of the inverter/charger is connected or routed back to the inverter/charger’s AC input terminal or if the AC internal transfer relay error is detected.

What does Load Shaving allow?

Load shaving (Load Shave) allows the Conext SW to support (or assist) the AC source in powering local loads during a defined window of time (LoadShaveStart and LoadShaveStop).

What does Load Shaving allow the inverter to control?

It allows the inverter to control how much current can be drawn from the AC source.

When does the Conext SW transition to load shaving mode?

The Conext SW transitions to load shaving mode only when both the phase currents exceed Load Shave Amps.

How does the Conext SW limit the peak load on the AC input?

It uses battery power to limit the peak load on the AC input by providing the difference in amps between the actual load current and the current limit set in Load Shave Amps.

In the scenario where the Load Shave Amps = 5A, L1 = 7A of AC load, and L2 = 3A of AC load, will the Conext SW enter into the AC load shaving mode?

No, the Conext SW will not enter into the AC load shaving mode because one of the phase currents (L1 or L2) is lower than the value of Load Shave Amps. (L2 = 3A) < (Load Shave Amps = 5A)

In the scenario where the Load Shave Amps = 5A, L1 = 7A of AC load, and L2 = 9A of AC load, will the Conext SW enter into the AC load shaving mode?

Yes, in this scenario, the Conext SW enters into the AC load shaving mode because both phase currents exceed the value of Load Shave Amps.

In the scenario where the Load Shave Amps = 5A, L1 = 7A of AC load, and L2 = 9A of AC load, how many amps will the Conext SW shave off of each phase?

The Conext SW will shave off 2A from each phase, meaning, the current draw from L1 will be limited to 5A and L2 limited to 7A. (L1 = 7A) > (Load Shave Amps = 5A) The difference between these two values is 2A.

When the battery is in charge mode, how is the total AC input current limited?

When the battery is in charge mode, the total AC input current is limited by 80% of Load Shave Amps to avoid the fluctuation between battery charge and discharge.

How is the fluctuation between battery charge and discharge described?

If the AC input current limit is the same value as Load Shave Amps in battery charge mode, the charge current can be higher than the limit value due to the charge dynamics. Under this condition, the battery will enter into discharge mode because the AC current is higher than Load Shave Amps. After the battery is in discharge mode, the battery will go back into charge mode again because the load current is smaller than Load Shave Amps.
Therefore, the battery will fluctuate between the charge and discharge modes. In order to avoid this fluctuation, a hysteresis band is set by limiting the AC input current to 80% of Load Shave Amps when the battery is in the charge mode.

In a grid-interactive backup system, what does load shaving combined with time-of-use metering help reduce?

In a grid-interactive backup system, load shaving combined with time-of-use metering helps reduce utility peak demand surcharges.

In an off-grid system with a generator, what can load shaving be used for?

In an off-grid system with generator Load shaving can be used to support the generator.

If the generator is unable to provide enough current to run loads in the system, what does load shaving ensure?

If the generator is unable to provide enough current to run loads in the system, load shaving ensures that the system does not exceed the generator’s current rating.

How is the system prevented from exceeding the generator’s current rating?

This is done by matching the generator’s manufacturer recommended current rating with the Load Shave Amps setting.

What do utilities use time-of-use metering for?

Utilities use time-of-use metering to set utility charges during peak usage hours and to impose a surcharge.

How can the Conext SW be configured to overcome peak charges?

The Conext SW can be configured (using the LoadShaveStart, LoadShaveStop and charger block settings) to overcome these peak charges by using utility power to charge the battery bank during the inexpensive energy hours and consuming the battery energy during expensive energy hours.

If charger block is set between 9:00 AM and 10:00 PM and load shaving is set between LoadShaveStart=6:00 PM and LoadShaveStop=9:00 PM, when does charging on AC input stop?

Charging on AC Input stops at 9:00 AM.

If charger block is set between 9:00 AM and 10:00 PM and load shaving is set between LoadShaveStart=6:00 PM and LoadShaveStop=9:00 PM, what does the inverter continue to do?

The inverter continues to pass utility AC through to the loads.

If charger block is set between 9:00 AM and 10:00 PM and load shaving is set between LoadShaveStart=6:00 PM and LoadShaveStop=9:00 PM, and charging is required during the charger block period, what can the Conext SW use to charge the battery bank?

If charging is required during the charger block period, then Conext SW can use an alternative external renewable energy source such as an MPPT solar charge controller to charge the battery bank.

If charger block is set between 9:00 AM and 10:00 PM and load shaving is set between LoadShaveStart=6:00 PM and LoadShaveStop=9:00 PM, when does the inverter connect to the utility grid?

The inverter connects to the utility grid at 6:00 PM.

If charger block is set between 9:00 AM and 10:00 PM and load shaving is set between LoadShaveStart=6:00 PM and LoadShaveStop=9:00 PM, what does the inverter use to support running the loads?

The inverter supports running the loads using the batteries.

If charger block is set between 9:00 AM and 10:00 PM and load shaving is set between LoadShaveStart=6:00 PM and LoadShaveStop=9:00 PM, how long does the inverter continue to run the loads?

The inverter continues to run the loads until 9:00 PM.

If charger block is set between 9:00 AM and 10:00 PM and load shaving is set between LoadShaveStart=6:00 PM and LoadShaveStop=9:00 PM, when does the Conext SW stop supporting the utility grid?

The Conext SW then stops supporting the utility grid and passes utility AC through to the loads at 9:01 PM.

If charger block is set between 9:00 AM and 10:00 PM and load shaving is set between LoadShaveStart=6:00 PM and LoadShaveStop=9:00 PM, when does utility AC begin maintaining the batteries?

At the end of the charger block, at 10:00 PM, utility AC begins maintaining the batteries based on charger settings.

What does the above example allow an external renewable energy source to be utilized as?

The above example allows an external renewable energy source to be utilized as a primary charging source during a desired time window.

What can the charger be used for when the utility rates are low?

The charger (using utility power connected to AC Input) can then be used to supplement battery charging when the utility rates are low.

How is current regulated in Figure 1-2, Load Shaving in Action?

Current is regulated by placing a limit (Load Shave Amps) on the current of the AC source.

When using the system for time-of-use metering, how should the system be designed?

When using the system for time-of-use metering, the system should be designed with a battery capacity large enough to support loads during the entire peak rate period without reaching the low battery cut out (Low Batt Cut Out) setting.

What can load shaving be used with to support self-consumption?

Load shaving can also be used with time-of-use metering and enhanced AC support feature to support self-consumption.

Why is AC support similar to load shaving?

AC Support is similar to load shaving because in both cases the Conext SW inverter supplements AC current.

Unlike load shaving, how does AC Support minimize the AC input current to the Conext SW?

However, unlike load shaving, AC Support minimizes the AC input current to the Conext SW as long as the battery’s SOC (state-of-charge) or battery voltage conditions allow it.

What does AC Support allow the Conext SW to support?

AC Support allows the Conext SW to support local loads by converting excess power from external DC sources connected to its battery bank.

What are examples of external DC sources?

Examples of external DC sources are MPPT solar charge controllers.

When local loads demand more energy from the external DC sources, when can extra current be pulled in from the AC source?

When local loads demand more energy from the external DC sources then extra current can be pulled in from the AC source as a last resort.

When operating without a solar charge controller in the system, what should the battery charge cycle be set to?

When operating without a solar charge controller in the system, set the battery charge cycle to 2StgNoFloat to allow AC Support to function immediately after the absorption charge stage.

When Conext SW is operating in AC support mode, what AC loads does it compensate for?

When Conext SW is operating in AC support mode, it only compensates AC loads which are connected to both phases and having equal power.

What will happen to the difference in power between the two phases?

The difference in power between the two phases will be drawn from the AC source.

In the scenario where L1 = 3A of AC load, and L2 = 3A of AC load, how many amps does the Conext SW inject into each phase?

In this scenario, the Conext SW injects 3A into each phase to offset both loads.

In the scenario where L1 = 5A of AC load, and L2 = 3A of AC load, how many amps does the Conext SW inject into each phase?

In this second scenario where power from the two loads is unequal, the Conext SW still injects 3A (the lesser of the two AC loads) into each phase.

In the scenario where L1 = 5A of AC load, and L2 = 3A of AC load, where will the difference of 2A on L1 be drawn from?

However, the difference of 2A on L1 shall be drawn from the grid.

How many different ways does AC support behave?

AC Support behaves three different ways depending on the type of equipment that is installed in the Xanbus network with the Conext SW.

What are the different ways AC Support behaves?

SOC – Xanbus-enabled Conext Battery Monitor is installed
Enhanced – Xanbus-enabled MPPT solar charge controller is installed
Regular – neither Xanbus-enabled battery monitor nor MPPT solar charge controller is installed

With AC support on SOC (AC Supp on SOC) enabled, what does Conext SW maximize?

With AC support on SOC (AC Supp on SOC) enabled (default setting), Conext SW maximizes power utilization using stored energy in a battery bank within a grid-interactive backup power system.

What does AC support mode allow the Conext SW to accurately determine?

AC support mode allows the Conext SW to accurately determine when grid power can be used to supply energy to the loads by knowing the state-of-charge (SOC) of the battery bank.

How is the SOC of a battery bank monitored?

The SOC of a battery bank is monitored by using a Xanbus-enabled battery monitor.

What determines when AC support mode is engaged?

The SOC entry point (AC Supp Start Soc) which is a high percentage value determines when AC support mode is engaged.

What determines when AC support mode is disengaged?

The SOC exit point (AC Supp Stop Soc) which is a low percentage value determines when AC support mode is disengaged.

When does Enhanced AC Support (EnhancedACSup) work?

Enhanced AC Support (EnhancedACSup) works when power systems are DC coupled with a Xanbus-enabled MPPT Solar Charge Controller.

What does Enhanced AC Support mean for DC power from a renewable source?

This means that DC power from a renewable source such as an MPPT Solar Charge Controller is used to charge the battery bank while simultaneously utilizing its power (by way of inverting) to power loads.

What controls entry and exit to enhanced AC support?

Entry and exit to enhanced AC support are controlled by the MPPT charger so that they can control the state-of-charge of the batteries.

When is AC power from the grid utilized?

AC power from the grid is utilized only when load demand exceeds power available from the MPPT charger for charging and supplying the loads.

In Figure 1-3 AC Support Mode using SOC, what is entry and exit into AC Support Mode determined by?

Entry and exit into AC Support Mode is determined by the SOC.

In Figure 1-3 AC Support Mode using SOC, is the AC Support mode engaged?

Yes, in this case, AC support mode is engaged.

In Figure 1-3 AC Support Mode using SOC, how many amps of offset are allowed from the grid to flow into AC IN under all conditions?

To prevent injecting current into the grid from the inverter, there is less than 2 amps of offset allowed from the grid to flow into AC IN under all conditions.

In Figure 1-4 Enhanced AC Support, what is entry and exit into Enhanced AC Support determined by?

Entry and exit into Enhanced AC Support is determined by the MPPT.

In Figure 1-4 Enhanced AC Support, how many amps of offset are allowed from the grid to flow into AC IN under all conditions?

To prevent injecting current into the grid from the inverter, there is less than 2 amps of offset allowed from the grid to flow into AC IN under all conditions.

When enhanced AC support mode is enabled, what does the Conext SW automatically track?

When enhanced AC support mode is enabled, the Conext SW automatically tracks the MPPT solar charge controller’s charging voltage as it transitions from bulk to absorption to float.

By tracking the voltage, what is the Conext SW able to do?

By tracking the voltage, the Conext SW is then able to execute and finish the charging cycle using DC power from the solar charge controller while converting its excess DC power to AC power to support the grid by supplying more current.

What does the Conext SW prioritize before supporting the loads?

Conext SW only uses excess DC power not required by the battery to support the grid, thus, it prioritizes charging the battery before supporting the loads.

Why is battery health improved?

Battery health is improved because the system always executes a three-stage charging of the battery that ensures battery SOC is as close as possible to 100% at all times.

What may systems that use a fixed voltage for AC support (or similar) do that may degrade battery performance?

Systems that use a fixed voltage for AC support (or similar) start to support loads sooner and may not fully charge the battery bank, leaving the battery in a partial SOC. Prolonged periods of partial SOC can degrade battery performance. Enhanced AC support limits this degrading effect.

What happens to PV energy from the charge controller during the BULK phase of the Enhanced AC Support Charging Stages?

During this phase, all PV energy from the charge controller is diverted to the battery for maximum charging.

Does the Conext SW engage AC support during the BULK phase of the Enhanced AC Support Charging Stages?

No, during this phase, the Conext SW does not engage AC support.

What happens to the charge controller output once the charge controller is in the ABSORPTION phase of the Enhanced AC Support Charging Stages?

Once the charge controller is in the absorption phase, the charge controller output is split between the battery and Conext SW for supporting AC loads.

What happens as the battery approaches full charge during the ABSORPTION phase of the Enhanced AC Support Charging Stages?

As the battery approaches full charge, more power from the charge controller is diverted to Conext SW for AC support.

What happens to the charge controller output once the battery is full and the charge controller transitions to the FLOAT phase of the Enhanced AC Support Charging Stages?

Once the battery is full and the charge controller transitions to the float phase, almost all the charge controller output is used by Conext SW to support AC loads.

What does the battery receive during the FLOAT phase of the Enhanced AC Support Charging Stages?

The battery only receives a trickle charge to maintain a healthy state of charge.

If no Xanbus-enabled devices, such as an MPPT charge controller, are connected to the power system, then what is entry and exit into AC support mode based on?

If no Xanbus-enabled devices, such as an MPPT charge controller, are connected to the power system, then entry and exit into AC support mode is based solely on battery voltage monitored by Conext SW.

If the battery voltage is above a set limit (AC Supp Volts), is the AC support mode engaged?

Yes, if the battery voltage is above a set limit (AC Supp Volts), then AC support mode is engaged.

With its charger enabled, when does the Conext SW enter AC support mode?

With its charger enabled, the Conext SW enters AC support mode only after completing a charge cycle when it is first powered up or reconnected to the grid.

What should the Conext SW’s battery charge cycle be set to for regular AC support mode?

For regular AC support mode set the Conext SW’s battery charge cycle to 2StgNoFloat to allow AC Support feature to function immediately after the absorption charge stage.

What does the Conext SW have that postpones the engagement of two grid-interactive features?

Conext SW has a delay feature that postpones the engagement of two grid-interactive features, namely load shaving and AC support, until a connected MPPT solar charge controller has had a chance to charge the battery for two hours in Float mode.

What is the delay feature called?

The delay feature is called PLSDelay in SCP.

What does the delay feature prioritize?

The delay feature prioritizes the MPPT solar charge controller’s ability to sufficiently charge the battery bank.

How does the delay feature work?

The feature works by inhibiting grid-interactive operation for two hours from the time the charge controller transitions from Absorption to Float charging.

What does this delay feature allow?

This allows the battery to be fully charged before either load shaving or AC support mode is engaged.

Where is this feature useful?

This feature is useful in applications where battery micro-cycling is to be minimized in order to maximize battery life.

If the Load Shave = Enabled, LoadShaveStart = 10:00 AM, and PLSDelay = Enabled, Absorption to float charging starts at 7:00 AM and load shaving is set to start at 10:00 AM. Absorption transitions to float at 9:00 AM. When does the load shaving actually start?

Absorption transitions to float at 9:00 AM but because PLSDelay is enabled, the 2-hour delay inhibits load shaving to actually start at 10:00 AM. Because of the 2-hour delay, load shaving does not start until 11:00 AM.

In Figure 1-6 Regular AC Support without Xanbus Devices, what is the entry and exit into AC Support Mode determined by?

Entry and exit into AC Support Mode is determined by the battery voltage.

In Figure 1-6 Regular AC Support without Xanbus Devices, why is AC support mode engaged?

In this case, AC support mode is engaged because the actual battery voltage is above the AC support voltage level. actual battery voltage = 25V AC support voltage = 24V

In Figure 1-6 Regular AC Support without Xanbus Devices, how many amps of offset are allowed from the grid to flow into AC IN under all conditions?

To prevent injecting current into the grid from the inverter, there is less than 2 amps of offset allowed from the grid to flow into AC IN under all conditions.

Under what conditions does the 2-hour delay work?

The 2-hour delay works only under the following conditions:

Conext SW’s battery charge cycle must be set to 2StgNoFloat
PLSDelay must be set to Enabled
an MPPT solar charge controller must be connected and detected in the Xanbus network
the feature must not have been activated within that day

Can this configuration be enabled or disabled?

Yes, this configuration can be enabled or disabled in “Advanced Features Menu”.

What is the default setting for PLSDelay?

The default setting for PLSDelay is Disabled.

What is Off-grid AC Coupled system architecture often used to create?

Off-grid AC Coupled system architecture is often used to create a stand-alone grid.

What does this commonly mean?

Commonly this means that PV inverters are connected to the output of a battery-based inverter/charger putting both on the same AC bus along with the AC loads.

What does the battery powered inverter charger provide in this scenario?

In this scenario, the battery powered inverter charger provides the necessary frequency and voltage to enable the PV inverter to produce power.

What must this type of system be able to maintain at all times?

This type of system must be able to maintain power generation in balance with power consumption at all times.

If there is more power being generated than can be consumed by the loads, what will happen?

If there is more power being generated than can be consumed by the loads, power will flow to the inverter/charger and be converted to DC power which flows into the battery.

Once the battery reaches capacity, what must happen to maintain the balance between generation and consumption?

Once the battery reaches capacity, power generation by the PV inverter must be curtailed to maintain the balance between generation and consumption.

As the battery bank reaches capacity, how does the Conext SW curtail PV inverter generation?

As the battery bank reaches capacity, Conext SW curtails PV inverter generation by raising the AC line frequency causing compatible PV inverters to reduce their power output in an orderly manner.

What is Active Frequency Shift Power Curtailment?

This is called Active Frequency Shift Power Curtailment.

During a grid outage, why will even a home with a grid-tie PV inverter system be without power?

During a grid outage, even a home with a grid-tie PV inverter system will be without power because PV inverters cannot produce power without the presence of a reference voltage and frequency.

To enable the PV inverter to provide power during a grid outage, how is the Conext SW retrofitted?

To enable the PV inverter to provide power during a grid outage the Conext SW is retrofitted in front of the PV inverter.

Where is the PV inverter rewired to?

The PV inverter is rewired from the grid connection to a critical load (sub) panel.

Where is the AC Couple on?

The AC Couple is on the Conext SW AC Output port.

What should you consult to determine if your PV inverter is compatible with Active Frequency Shift Power Curtailment?

Consult the manufacturer’s specifications to determine if your PV inverter is compatible with Active Frequency Shift Power Curtailment.

Is the Conext SW’s AC coupling function enabled by default?

Yes, Conext SW’s AC coupling function is enabled by default.

When should the AC coupling advanced setting remain enabled?

The AC coupling advanced setting should remain enabled except in cases when the DC voltage level is allowed to have large variations and the line frequency needs to remain constant.

Where can further details about AC Coupling be found?

Further details about AC Coupling can be found in the document “AC Coupling Solutions Guide (Document Number: 976-0240-01-01)”.

What is AC Couple Smart Charge?

AC Couple Smart Charge is a feature of the Conext SW that prioritizes battery charging over energy export to local AC loads connected upstream of the Conext CSW battery inverter.

What must be enabled for the AC Couple Smart Charge feature to be functional?

AC Coupling must be enabled for this feature to be functional.

In AC-coupled configuration and with the grid present, what does the Conext SW monitor?

In AC-coupled configuration and with grid present, the Conext SW monitors flow of power from its load port (AC Output) to the utility grid input (AC Input).

When power flow to the grid is detected and the battery needs charging after a short delay, what does the Conext SW initiate?

When power flow to the grid is detected and the battery needs charging after a short delay, the Conext SW initiates a bulk charging cycle by switching to charge mode and drawing AC power to charge the battery.

How much energy does the Conext SW draw during bulk charging cycle?

It only draws enough energy to keep the flow of power to the grid to zero.

As long as the battery is able to accept the energy, what will the Conext SW continue doing?

As long as the battery is able to accept the energy, the Conext SW will continue diverting excess PV production to the battery.

Once the battery bank is at a level such that not all excess energy from the PV Inverter is being absorbed, what will happen to the balance?

Once the battery bank is at a level such that not all excess energy from the PV Inverter is being absorbed, the balance will then flow out to upstream loads in the house that are not connected to the Conext SW’s AC output port.

If PV production is lost for a prolonged period of time and the battery bank discharges below the Recharge Volts setting, what will the Conext SW initiate?

If PV production is lost for a prolonged period of time and the battery bank discharges below the Recharge Volts setting, the Conext SW will initiate a normal charge cycle and use power from the grid to charge the battery.

In all of the above modes of operation, what exports energy to the grid?

In all of the above modes of operation, only the PV Inverter exports energy to the grid.

Can the Conext SW sell to the grid?

The Conext SW itself cannot sell to the grid – it simply passes energy from the PV inverter to the grid.

What must the PV Inverter be since it assumes responsibility for anti-islanding protection?

For this reason, the PV Inverter must be fully grid code compliant as it assumes responsibility for anti-islanding protection.

What should be checked to minimize the risk of incompatible equipment?

Check that the PV Inverter warranty covers off-grid applications, specifically AC coupling with a battery- based inverter.
Check that the PV Inverter is capable of operating when it is AC-Coupled with the inverter/charger which forms the local grid. PV Inverters with an impedance sensing anti-islanding scheme are not compatible with the inverter/charger.
Check that the PV Inverter can be configured to curtail power when the grid frequency rises above 50.5 Hz and that power ceases to flow when the frequency reaches 52.0 Hz.

What may happen if the instructions to minimize the risk of incompatible equipment are not followed?

Failure to follow these instructions could result in damage to equipment not covered by warranty.

Why should a generator never be connected to the AC Input terminal of a battery inverter configured for AC coupling?

Never connect a generator to the AC Input terminal of a battery inverter configured for AC coupling. The inverter will not be able to regulate the current being backfed into the AC input and may backfeed AC current into the generator.

What may happen if a generator is connected to the AC Input terminal of a battery inverter configured for AC coupling?

Failure to follow this instruction can result in equipment damage.

What should be done to prevent battery damage in a micro-grid AC system?

To prevent battery damage in a micro-grid AC system, use only firmware which has the AC coupling feature implemented. Always be sure to use the latest firmware available for your inverter.
Do not use a Lithium Ion battery pack in AC-Coupled inverters.

What may happen if the instructions to prevent battery damage in a micro-grid AC system are not followed?

Failure to follow this instruction can result in battery damage.

What does the feature called StoreInvState do?

You can enable or disable a feature called StoreInvState which, when enabled remembers the state of the inverter mode prior to a power down (that is, when AC and DC power sources are disconnected).

When the Conext SW is powered up again, what happens to the inverter mode?

When the Conext SW is powered up again, the inverter mode reverts back to its prior state.

What does the No Load Voltage Derating (NoLoadVD) feature do?

The No Load Voltage Derating (NoLoadVD) feature further reduces tare loss by adjusting output voltage by +4%/-5% of nominal, over the full load range.

What does this mean at 50% load?

That means at 50% load, the output voltage is at nominal but 5% below nominal at no load and up to 4% at full load.

What may result from the slight increase in overall operating efficiency?

The feature results in a slight increase on overall operating efficiency but may result in visible flicker of incandescent or similar lights during large sudden load changes.

How does Low battery cut out (Low Batt Cut Out) (LBCO) preserve battery life?

Low battery cut out (Low Batt Cut Out) (LBCO) preserves battery life by stopping the inverter when battery voltage drops down to the LBCO value for a few seconds (see LBCO Delay below), then battery charging commences.

Why is the LBCO Hysteresis value added to the LBCO value?

When charging starts, the voltage level jumps a little but enough that inverting might resume abruptly. Then, battery voltage goes down again and charging starts abruptly. To prevent the inverter from switching abruptly between inverting and charging, the LBCO Hysteresis value is added to the LBCO value to allow the battery voltage to reach a sufficient energy capacity level before inverting resumes.

How do I test the inverter using the front panel?

Press the Inv Enable button on the Conext SW on the front panel. The Inv Enabled LED illuminates.
Turn on the main AC breaker or AC disconnect to supply AC input power to the inverter.
Turn off the main AC breaker or AC disconnect to stop AC input power from going into the inverter.
Place a load on the inverter. This also usually means turning on the inverter’s AC distribution sub-panel’s breaker switch.
Connect a load such as a lamp into an outlet connected to the sub-panel circuit and turn it on. The lamp lights up.
Repeat step #2. The lamp will remain lit up.
Repeat step #3. The inverter/charger should invert immediately. The transfer relay will make a clicking sound and the Inv Enabled LED will illuminate. The lamp should remain lit up. If any part of this test does not happen correctly, determine the cause before continuing to use the unit.
Monitor the Conext SW front panel. The indicator LEDs on the front panel show you the operating status of the Conext SW. A description of the LEDs is provided in Table 3-1. If none of the front panel LEDs are on, see “General Troubleshooting Guidelines.”

What do fault detections do and what actions are sometimes required?

A fault detection condition affects the operation of the unit. A fault detection sometimes requires user intervention by clearing the condition using the Clear Fault button on the inverter/charger’s front panel. Press the button once to clear the condition. See “Troubleshooting” for information on clearing fault detections from the SCP.

What do warnings do?

A warning alerts you to a condition that could possibly affect the operation of the unit. A warning usually precedes a fault detection condition.

What are the front panel LED indicators and what do they mean?

Icon	LED Status	Action (or Status Item)
Inv Enabled	Steady Green	If generator or grid AC is unavailable and operating conditions are met, the Conext SW will produce AC voltage to power loads. You can run your appliances from the inverter.
	Flashing Green	The inverter is in AC Support or Load Shave mode. You can run your appliances from the inverter.
AC IN	Steady Green	When the Conext SW is connected to a generator or grid and is producing qualified AC, the AC IN light illuminates. You can run your appliances using passed-through AC.
	Flashing Green	Conext SW is connected to a qualified AC source, is charging and passing-through power to AC loads. Your battery bank is being replenished and AC loads are receiving power from a qualified AC source.
Fault	Steady Red	A fault has been detected on the network. Investigate and clear the fault detection condition.
Warning	Flashing Red	A warning is detected. Investigate by examining warning logs on SCP.

What are the operating limits for inverter operation for Temperature?

The Conext SW series of inverter/chargers will operate at rated power continuously at 77 °F (25 °C) with some models capable of continuous operation at much higher ambient temperature. However, the continuous power rating at elevated ambient temperature may differ between models. In higher ambient temperatures, if the loads draw full power for an extended period of time, the unit may shut down to protect itself against overheating.

What are the operating limits for inverter operation for Surge Power?

The Conext SW series of inverter chargers feature a surge rating of 200% of rated power for five seconds at 77 °F (25 °C). Operating the inverter/charger in conditions outside of normal rated power and temperature limits, however, will result in thermal shutdown and/or significantly decreased performance.

What are the operating limits for inverter operation for Difficulty on starting loads?

The inverter/charger should be able to operate all AC loads rated at or below its power rating. Some high horsepower induction motors used in pumps and other motor-operated equipment require very high surge currents to start, and the inverter/charger may have difficulty starting these loads.

What should I do if I have problems starting certain loads?

If you have problems starting certain loads, ensure that:

The battery connections are tight and clean.
The DC cabling is no longer than the recommended length.
The AC wiring is of recommended size.
The battery is of sufficient capacity and is fully charged.

What will the Conext SW always yield when inverting and during AC bypass?

The Conext SW always yields a split-phase output when inverting and during AC bypass.

A split-phase input through L1 and L2 yields a split-phase output of L1 and L2.
Single-phase input through L1 yields a split-phase output of L1 and L2.
A single-phase input through L2 does not produce any output. Only the input in Line 1 is capable of qualifying the AC coming from the power source.

What happens with Battery power during AC bypass?

When sufficient AC is detected by the inverter/charger and the battery is sufficiently charged, the AC is automatically passed through to the loads. However, if the battery is less than 12 V (for 24-volt models), 24 V (for 48-volt model), or had been disconnected, the inverter/ charger will not pass grid AC through to the loads.

What should I not do in order to prevent equipment damage?

Do not energize and operate the inverter/charger with an AC source before connecting a battery. Do not rely solely on AC bypass power to provide energy to connected loads. Always operate with a battery connected to the inverter/charger. Always try to balance the load between lines L1 and L2. Damage to the internal power transformer may occur if one line is overloaded when the other line is unloaded.

What are the operating limits for charger operation?

By default, the maximum charger output current is the rated charger output current for the particular model. Using the SCP, you can reduce the total output if you change the maximum charge rate (Max Chg Rate) on the Conext SW Basic Settings menu or Charger Settings menu under Advanced Settings. The charger can charge batteries when the AC input voltage line-to-neutral is within the minimum and maximum range of 95 to 135 VAC. They are the default minimum and maximum settings. The minimum range setting can be adjusted from 78 to 115 VAC and the maximum range setting from 125 to 140 VAC. The charger can also be configured to accept and operate from a wide AC source frequency of 44–70 Hz. The default setting is 55 Hz for low frequency and 65 Hz for high frequency. This wide range allows the Conext SW to charge your batteries even when incoming AC voltage is less than the typical 60 Hz.

What is Power Share?

The Conext SW charger uses both split-phase lines AC INPUT L1 and L2 to charge the batteries at full capacity. However, if only AC INPUT L1 is used, charge capacity is reduced to 50%. Consequently, the Conext SW charger shares incoming power with AC loads on both split-phase lines with a current limit of 30 amps for charging and pass-through AC. However, when AC is qualified only on one line at AC INPUT L1, the current draw from that input is limited to 15 amps (SW 4024 120/240) and 13 amps (SW 2524 120/240) for charging and AC pass-through. The AC loads have priority, which means that the charger will reduce its output with large AC loads and increase the output again when the AC load decreases. The regulatory maximum for continuous AC loads is 80% of the breaker rating that the loads are connected to. The Conext SW senses pass-through current going to the AC load. The difference between the pass-through (load) and 80% of the Power Share setting is the current that is available for charging the batteries.

How does the Power Share setting affect charging?

For example, if the AC input of the Conext SW is from an AC panel with a 30-amp breaker, the Power Share setting on the SCP should be selected as 30-amp. Based on this, the charger will control the charge current so that the total current draw is equal to or less than 24 amps in this case. Should the load current be more than about 24 amps, the charger output will reduce to zero (0) amp, but the Conext SW will continue to supply the loads. The Conext SW will continue to pass-through power to the loads, even if the load current exceeds the Power Share setting. In this case, it will be up to the user to remove/disconnect loads if tripping the AC input breaker supplying the Conext SW is to be avoided.

What does the SCP provide?

The SCP provides operating, configuring, and monitoring capability for your Xanbus system.

What does the System Control Panel do?

What are the functions of the Standby button and how do they work?

The Standby button has two functions, depending on how it is pressed. First, when only the Standby button is pressed, it can disable inverting and charging for all Conext SW units in the system. Second, when it is pressed simultaneously with the Exit button, this action puts the entire system into Standby mode. Pressing the Standby button produces the same result as disabling “Invert” and “AC Charge” from the System Settings menu on the SCP. Pressing the Standby button momentarily affects only Conext SW units; it does not affect charge controller operation. After disabling inverting and charging with the Standby button, the system continues to pass AC input through to the loads. Pressing the Exit and Standby buttons at the same time puts the entire Xanbus network system (including charge controllers) into Standby mode. In Standby mode, the Conext SW stops passing AC input through to the loads. After the keypress command to enter Standby mode, the AGS – Automatic Generator Start (if installed) shuts down the generator (if it is running) after a cool-down cycle.

It is recommended to leave the Setup menu in the Basic Settings format to help prevent unintended configuration. If the Setup menu displays “Advanced Settings,” press Enter + up arrow + down arrow at the same time. The Setup menu should then display Basic Settings as the last item on the menu.

What is the Batt Type setting?

Sets the system battery chemistry and type: Flooded, AGM, Gel, and Custom.

What is the Batt Capacity setting?

Selects the system battery capacity in amp hours.

What is the Max Chg Rate setting?

Sets the percentage of the maximum DC output current that is available to the charger. The maximum DC output current for different models is:

SW 2524 120/240 — 65 ADC
SW 4024 120/240 — 90 ADC
SW 4048 120/240 — 45 ADC

If multiple Conext SWs are charging the same battery bank, set each inverter’s Max Chg Rate to 1/n of the desired charge rate (where n is the number of inverter/chargers).

What is the Charge Cycle setting?

Sets the charging method:

3-Stage (bulk, absorption, float) or
2StgNoFloat (bulk, absorption, no float)

What is the ReCharge Volts setting?

Sets the recharging volts to tell the charger to initiate charging when the battery drains past the value setting.

What is the AC In Breaker setting?

Sets the breaker limit of incoming AC (generator or grid).

What is the Low Batt Cut Out setting?

Low Battery Cut Out (LBCO) controls when the inverter stops producing AC output due to a low battery voltage condition. The inverter will stop producing AC output only after this level has been reached for the period of time set by the LBCO Delay. This setting is not temperature compensated.

What is the LBCO Delay setting?

LBCO Delay controls how long the inverter is allowed to operate at or below the Low Batt Cut Out level before turning off due to a low battery voltage condition. The inverter will stop producing AC output only after the Low Batt Cut Out level has been reached for this uninterrupted period of time.

Once the inverter has shut off, the battery voltage must rise 2 volts above the Low Batt Cut Out setting for inverter operation to resume.

What is the Hi Batt Cut Out setting?

Hi Batt Cut Out sets the maximum battery voltage at which the inverter will operate. If the battery voltage exceeds this limit for more than one minute, the Conext SW displays a fault message and shuts down. The inverter will not support AC loads when in this condition. If a qualified AC source is present, the unit passes AC through to the loads. The inverter automatically restarts when the voltage drops to 3 volts below the Hi Batt Cut Out setting. If battery voltage continues to rise after shutdown, an external charger may still be charging the batteries. The Conext SW cannot control how external chargers operate.

What is the Search Watts setting?

Search Watts sets the Conext SW’s search sensitivity when search mode is enabled. When a load larger than this setting is present, the inverter starts producing AC output. Enabling search mode from the Setup menu can minimize power draw from the battery during periods of low demand from loads. Also see “Using Search Mode”.

What is the Search Delay setting?

Search Delay sets the time between search pulses. When searching for loads, the Conext SW sends out search pulses to determine if a load is present. If the Conext SW finds a load above the Search Watts setting, the inverter turns on. Conext SW power draw while in search mode decreases when Search Delay is increased, but the Conext SW’s response time to active loads is slower.

What is the Inv Block Start setting?

Sets the time to halt inverting.

What is the Inv Block Stop setting?

Sets the time to resume inverting.

How can you use the Low Battery Cut Out and LBCO Delay settings?

The Low Batt Cut Out setting is the lowest battery voltage level acceptable for use by the inverter. When the batteries discharge to the Low Batt Cut Out setting and are held at or below this level for the LBCO Delay time, the inverter output shuts down and transfers any available AC source (like an AC generator) to the charger to bring the battery level back above the Low Batt Cut Out setting. After shutdown, the inverter does not support any AC loads, and AC loads must be powered by an AC generator.

What is recommended if you are using an automatic generator starting system?

If using an automatic generator starting system, it is recommended to set the Xanbus AGS voltage trigger setting higher than the Conext SW Low Batt Cut Out voltage. Otherwise, inverter output turns off before the generator automatically starts, causing the battery voltage to recover slightly. This may then stop the Xanbus AGS from starting the generator or result in the inverter cycling on and off multiple times before the generator automatically starts.

If using an automatic generator starting system with the start trigger set to the same voltage as the LBCO voltage, do not set the LBCO Delay for less than the amount of time it takes the generator to start and connect. Otherwise, inverter output turns off before the generator automatically starts, causing the battery voltage to recover slightly. This may then stop the Xanbus AGS from starting the generator or result in the inverter cycling on and off multiple times before the generator automatically starts.

What is Low Battery Cut Out Hysteresis?

Low battery cut out (Low Batt Cut Out) (LBCO) preserves battery life by stopping the inverter when battery voltage drops down to the LBCO value for a few seconds then battery charging commences. When charging starts, the voltage level jumps a little but enough that inverting might resume abruptly. Then, battery voltage goes down again and charging starts abruptly. To prevent the inverter from switching abruptly between inverting and charging, the LBCO Hysteresis value is added to the LBCO value to allow the battery voltage to reach a sufficient energy capacity level before inverting resumes. This feature contributes to battery health.

Why use Search mode?

Search mode allows the inverter to selectively power only items that draw more than a certain amount of power, which can result in power savings.

The Conext SW has a no-load power draw of about 38 W (SW 2524 120/240) and 40 W (SW 4024 120/240). Enabling Search mode reduces this power draw to less than 8 W for all models.

How does Search mode operate?

Search mode operates differently in single-unit and multiple unit installations.

How does Search mode work in single unit installations?

When a single Conext SW has Search mode enabled, the inverter sends electrical search pulses through its AC output. These search pulses search for connected AC loads. The delay between search pulses is set using the Search Delay setting. After a load larger than the Search Watts setting is detected, the inverter turns on.

How does Search mode work in multiple unit installations?

Search mode is automatically enabled in multiple unit installations with two paralleled Conext SW units. Only the master Conext SW operates, and the slave unit comes online only when the load exceeds approximately 60% of the rated output of the master unit. When the load drops below 20% of the master’s rated output, the slave unit turns off.

When should you set up Search mode?

The Search mode feature is only valuable if the inverter can spend a couple of hours “sleeping” each day. Therefore, if Search mode is to be used it must be adjusted properly. The initial adjustment should be made so that the inverter comes on only when needed.

Certain types of loads can cause Search mode not to work as expected. These types of loads are described on “Problem Loads”. If these kinds of loads are in the system, follow the suggestions given to eliminate the problem. If the problem loads cannot be eliminated, there are two work-around solutions:

What are the two work-around solutions if you have problem loads and Search mode is not working as expected?

Disable Search Mode from the main Conext SW Setup menu, causing the inverter to always remain at full output voltage.
Use a search-friendly companion load whose only purpose is to be switched on to wake up the inverter to power the load that is unable to bring the inverter out of Search mode.

What should you keep in mind about Search mode?

Search mode, by function, cannot work with clocks and timers or devices that need power 24 hours a day. Examples of devices with timers include video recorders, coffee makers with brew timers, refrigerators, and freezers with defrost timers. Examples of devices that need power 24 hours a day include telephone answering machines, alarm systems, motion detection lights, and some thermostats.
When the inverter is searching the output for loads, lights that have a wattage lower than this setting may flash momentarily.

How can you use Inverter Block?

The Inverter Block feature halts inverter function for a period of time each day. This period of time is defined by the Inv Block Start and Inv Block Stop settings. Inverter Block allows you to control which time period is not ideal for inverting. This can be a time period when conserving battery power is more important than running loads.

How does the Inverter Block work?

The Inverter setting must be initially Enabled in order for the Inverter Block to work as intended. The Inv Block Start setting disables inverter function if the inverter is initially enabled and then Inv Block Stop enables the inverter function. However, if the Inverter setting is initially Disabled when Inv Block Start commences, then the succeeding Inv Block Stop will not enable inverter function automatically. The inverter will remain disabled.

Setting the Inv Block Start and Inv Block Stop to the same time disables Inverter Block. Disabling Inverter Block means that inverting is allowed to occur at any time when the right conditions for inverting exist.

What should you keep in mind about Inverter Block settings in a multiple unit configuration?

In a multiple unit configuration, set the same Inverter Block settings to both the master and slave units.

What is the Default Batt Temp setting?

Selects the battery temperature charging compensation if a battery temperature sensor is not installed. In the absence of a battery temperature sensor, the charger uses one of three settings: Cold (50 °F/10 °C), Warm (77 °F/25 °C), or Hot (104 °F/40 °C).

What is the Absorb Time setting?

Sets the maximum time spent in the absorption stage, before transitioning to float or no float.

What should you keep in mind about the Absorb Time setting?

The Absorb Time setting resets to its default value of 180 minutes when the Battery Type is changed except when changing to Custom Settings. In Custom Settings, the Absorb Time setting will not reset to its default value.

What is the Auto Charge Enable setting?

When this setting is enabled, it overrides the “Charger” function to begin charging automatically when qualified AC is present. This happens even when the charger function is previously disabled.

What is the Chg Block Start setting?

Sets the time to halt charging.

What is the Chg Block Stop setting?

Sets the time to resume charging.

When can the Conext SW operate as a battery charger?

When AC power is available, the Conext SW can operate as a battery charger. Different battery types and chemistries require different charging voltage levels. Not charging batteries at the required levels can shorten battery life or damage the batteries. The Conext SW is configured at the factory to work with the battery types recommended for inverter applications. If the default settings do not work for your specific installation, you can adjust the charge stage settings (as recommended by the battery manufacturer) on the Custom (Battery) Settings menu.

How does the multi-stage charging process work?

The charging cycle is a multi-stage process. Whenever qualified AC power is present at the inverter’s input, it passes power through to the connected load and begins charging the batteries.

What happens during the Bulk Stage of the multi-stage charging process?

Bulk charge is the first stage in the charging process and provides the batteries with a controlled, constant current. Once the battery voltage rises to the bulk voltage threshold, the charger switches to the Absorption stage.

What happens during the Absorption Stage of the multi-stage charging process?

Absorption charge is the second stage of battery charging and provides the batteries with a controlled, constant voltage. During this stage, the current drawn by the batteries slowly decreases. When this current falls below 2% of the battery capacity, or when the configurable Absorb Time expires, the charger switches to the Float or NoFloat stage, depending on the selected charge cycle. The timer begins when the battery voltage is above the bulk termination voltage for three minutes.

What should you keep in mind about the multi-stage charging process?

If the AC input fails or drops below the lower VAC limit (as set in AC Settings), the complete multi-stage charge cycle (Bulk, Absorption, Float/No Float) restarts once the source AC returns to within tolerance condition. If the batteries are already nearly full, the charge cycle will take little time to complete.

What are the Bulk Voltage Settings for Different Battery Types?

Battery Type	24-Volt Models (Bulk Voltage)	48-Volt Model (Bulk Voltage)
	Termination	Preset Bulk
Flooded	28.4V	28.8V
Gel	28.0V	28.4V
AGM	28.2V	28.6V
Custom	28.8V (changeable)
LithiumIon	29.0V (changeable)

What should you keep in mind about the DC loads on the batteries?

If there are DC loads on the batteries, the charger’s current may never decrease to a level to initiate the next stage of charging. In this case, the charger would stay in absorption until the Absorb Time setting is reached. To make sure the charger does not remain in absorption for too long, adjust Absorb Time on the Charger Settings menu.

Also, the Absorption Time setting resets to its default value of 180 minutes when the Battery Type is changed.

What are the Preset Absorption Voltage Settings for Different Battery Types?

Battery Type	24-Volt Models	48-Volt Model
Flooded	28.8V	57.6V
Gel	28.4V	56.8V
AGM	28.6V	57.2V
Custom	28.8V (changeable)	57.6V (changeable)
LithiumIon	29.0V (changeable)	58.0V (changeable)

What happens during the Float Stage of the multi-stage charging process?

Float charge maintains a trickle charge on the batteries whenever AC is present on the Conext SW input. Float charging reduces battery gassing, minimizes watering requirements (for flooded batteries), and makes sure the batteries are in a constant state of readiness. When three-stage charging is selected, the charger automatically switches to the float stage after the batteries have received a bulk and absorption charge. The batteries will be maintained at the default float voltage level for the selected battery type or the voltage selected under Float Voltage on the custom battery Settings menu.

What should you keep in mind about the battery voltage?

The battery voltage can increase above the float voltage when using an external charging device such as PV arrays, wind turbines, or micro-hydro generators. Be sure to include appropriate charge management equipment with all external DC sources.

What are the Preset Float Voltage Settings for Different Battery Types?

Battery Type	24-Volt Models Preset Float Voltage	48-Volt Model Preset Float Voltage
Flooded	27.0V	54.0V
Gel	27.6V	55.20V
AGM	26.8V	53.6V
Custom	27.0V (changeable)	54.0V (changeable)
LithiumIon	26.85V (changeable)	53.6V (changeable)

How can you equalize-charge the batteries?

Many battery manufacturers recommend periodic equalize charging to level out the voltage between individual cells, improving battery performance and lifespan.

Over time, the battery’s electrolyte can become stratified, causing inactive areas in the plate material. If this condition is allowed to continue for extended periods, the battery plates can sulfate and become unusable. Equalizing the batteries is a controlled overcharging method that mixes up the electrolyte and reactivates the unused areas of the plate material, restoring batteries to a full state of charge.

Consult the battery manufacturer’s recommendation for equalize voltage settings. Equalization time is fixed at 60 minutes.

How can you start equalizing the batteries?

On the device Setup menu, highlight Equalize and select Enabled.

What are the Preset Equalization Voltage Settings for Different Battery Types?

Battery Type	24-Volt Models Preset Equalization Voltage	48-Volt Model Preset Equalization Voltage
Flooded	32.0V	64.0V
Gel	not applicable	not applicable
AGM	not applicable	not applicable
Custom	32.0V (changeable)	64.0V (changeable)
LithiumIon	not applicable	not applicable

What should you keep in mind about equalize-charging the batteries?

Only flooded or vented batteries should be equalize-charged. Hydrogen and oxygen gases are produced when batteries are equalize-charged.
In a system where more than one device is capable of equalizing batteries (such as a system including multiple Conext SW units and Solar Charge Controllers), there is no system-wide equalization command for all devices. To equalize with multiple devices, each would have to be enabled individually. Alternatively, equalization can be performed using only one device. During the equalization process, one device applies the equalization charge while the other devices continue to operate in synchronized charge mode, typically in float (three-stage charging) or no-float (two-stage charging).

How can you use Charger Block?

The Charger Block feature halts charging for a period of time each day. This period of time is defined by the Chg Block Start and Chg Block Stop settings. In areas where the utility charges variable rates for electricity, it is preferable to use utility power for charging only during non-peak hours. Charger Block can prevent utility power from being used for battery charging during peak billing periods. During the time period set between Chg Block Start and Chg Block Stop, AC input continues to be passed through to the loads. Inverter operation remains unaffected during the charger block period. During the Charger Block period, no charging occurs even if the batteries discharge below the ReCharge Volts setting. However, a Solar Charge Controller may charge batteries during the Charger Block period.

What happens when the charger is operating at the Chg Block Start time?

If the charger is operating (that is, in Float, Absorption, Bulk, or Equalize stage) at the Chg Block Start time, charging stops immediately and the charger enters an idle state identical to No Float. When the Charger Block period is over, the charger does not resume the charge stage that Chg Block Start interrupted. Instead, if the batteries are above the ReCharge Volts setting, the charger remains idle. If the battery voltage falls below the ReCharge Volts setting during the Charger Block period, the Conext SW Inverter/Charger begins a new charge cycle with the Bulk stage after the Charger Block period has expired (at the Chg Block Stop time).

What happens when you set the Chg Block Start and Chg Block Stop to the same time?

Setting the Chg Block Start and Chg Block Stop to the same time disables Charger Block. Disabling Charger Block means that charging is allowed to occur at any time when the right conditions for charging exist.

What is the Custom Battery Settings Menu?

The Custom Battery Settings menu can be viewed if Custom is selected as the Batt Type. This menu allows you to adjust charging and equalization voltage for batteries with specifications that fall outside the default settings for the battery types the Conext SW offers.

What is the AC Settings menu?

The AC Settings menu configures the voltage and frequency limits for AC In. These are the limits at which the Conext SW considers input voltage qualified—that is, suitable for charging batteries or powering loads. If the input voltage is not qualified according to these settings, the Conext SW transfers from using AC input to inverting.

What are the Setting Defaults and Ranges for the AC Settings menu?

Model
Setting	Default
ACIn Breaker	30A
ACIn Lo Volt	95V
ACIn Hi Volt	135V

What is the ACIn Breaker setting?

Sets the AC Input breaker size, based on the size of the installed AC breaker at the source. The Breaker size setting must not exceed the capacity of the AC source such as the grid or a generator. The Conext SW limits the maximum input current to this setting by derating its charging current. If the connected loads exceed the breaker setting, the AC breaker trips. The breaker may not trip if Load Shave is enabled and Load Shave Amps is configured not to exceed the AC source’s rated output current.

What are the Fault Detection Types and Behaviors?

Fault Detection type	Behavior
Automatic	Clears automatically if the fault condition that generated the message goes away. You can also acknowledge automatic fault detections without waiting for them to clear automatically.
Manual	Requires you to clear them by: <br> * Pushing the Clear Fault button on the Conext SW or on the device that generated the fault detection (if the fault condition still exists, the fault detection message reappears), and <br> * Correcting the condition that caused the fault
Escalating automatic	Clears automatically if the fault condition goes away, just like an automatic fault detection. <br> However, if an escalating automatic fault detection occurs several times within a defined time period, the escalating automatic fault detection becomes a manual fault detection, requiring user intervention. For example, if three fault detections occur in one minute, it will no longer clear itself but becomes a manual fault detection. Then you must identify the problem, correct the fault condition, and clear the fault detection or reset the device.

What are the Warning Types and Behavior?

Warning type	Behavior
Automatic warning	Clears automatically if the warning condition that generated the message goes away. You can also acknowledge automatic warnings without waiting for them to clear automatically.
Manual warning	Requires you to acknowledge it before you can proceed with configuring or operating the Conext SW. Manual warnings are usually in the form of a Yes/No question that you may acknowledge by pressing the Enter button on the SCP for Yes and the Exit button for No.

What are the Fault Detection Messages?

Code	Message	Type	Cause	Solution
F1	AC Output under voltage	Escalating Auto fault detection. Must occur 3 times in 30 seconds before becoming a manual fault detection.	Inverter voltage is under 210 volts.	Remove excessive load.

What is the AC Settings Menu?

Setting	Description
ACIn Lo Volt	Sets the minimum acceptable AC input voltage level from the AC source (generator or grid). <br> NOTE: It is recommended to leave this setting to its default value and not to set it to the maximum allowed. Doing so might inadvertently derate charging power in jurisdictions where the nominal AC mains voltage or generator output is at 110 volts.
ACIn Hi Volt	Sets the maximum acceptable AC input voltage level from the AC source (generator or grid).
ACIn Lo Freq	Sets the minimum acceptable AC input frequency from the AC source (generator or grid).
ACIn Hi Freq	Sets the maximum acceptable AC input frequency from the AC source (generator or grid).

What is the AC Support Menu?

Setting	Description	Default	Range
AC Supp Mode	Turns AC Support Mode feature on and off.	Enabled	Disabled, Enabled
AC Supp Volts	For 24-volt models <br> Battery voltage threshold in order to engage regular AC Support Mode. <br> cannot be set below Low Batt Cut Out + 2 volts <br> For 48-volt model <br> Battery voltage threshold in order to engage regular AC Support Mode. <br> cannot be set below Low Batt Cut Out + 2 volts	26.5V	For 24-volt models <br> 23.0V to 35.0V <br> 53.0V <br> For 48-volt model <br> 46.0V to 70.0V
Load Shave	Enables or disables the load shaving feature. When in this mode, the Conext SW operates until the batteries discharge to the Low Batt Cut Out threshold, after which the unit starts charging the batteries. The charger is automatically blocked during the load shaving time window.	Disabled	Disabled, Enabled
Load Shave Amps	Sets the maximum amount of current that can be drawn from the AC source input by the loads and battery charger combined. This setting determines the amperage level at which the inverter starts drawing power from the batteries to add to the power to meet load demands. Typically, this value is set to the peak usage surcharge threshold imposed by the utility, if applicable. See NOTE above.	24A	1A to 24A
LoadShave Start	Sets the time for when load shaving is engaged.	12:00 AM	Setting the Load Shave Start and Load Shave Stop to the same time disables scheduling.
LoadShave Stop	Sets the time for when load shaving is disengaged.	12:00 AM
AC Supp on Soc	Enables or disables the SOC monitoring for AC Support Mode. <br> This setting must be enabled for AC Supp Start Soc and AC Supp Stop Soc to take effect.	Enabled	Disabled, Enabled
AC Supp Start Soc	Sets the high percentage value of the SOC of the battery for AC Support Mode to engage. <br> Applicable only when AC Supp on Soc is enabled.	80%	70% to 100%
AC Supp Stop Soc	Sets the low percentage value of the SOC of the battery for AC Support Mode to disengage. <br> Applicable only when AC Supp on Soc is enabled.	50%	20% to 60%

What is the Multi Unit Menu?

Setting	Description	Default	Range
Dev Name	Allows the customizing of the default name for the inverter/charger. This setting is optional and does not affect operation. See “Setting the Device Name” on page 4–33.	CSW4024	will vary from model to model. <br> Can be changed by the user.
Dev Number	Allows setting of a unique unit number in a multiple-unit system. See “Setting the Device Number” on page 4–34.	00	00–31
Invtr Mode	For this to operate, one Conext SW must be configured to Master and the other as Slave, otherwise a system-wide fault is asserted.	Master	Master, Slave
AC In	For identifying the type of AC source when two power sources are available and an AGS is also present. <br> The Conext SW accepts only a single AC source – either from the grid or from a generator. In a power system where the Conext SW is solely connected to the grid and an AGS is neither present nor required, the AC In setting can be either Gen1 or Grid1. Therefore, the default value of Gen1 need not be changed. <br> In a situation where the AC source is a generator and the AGS is being used to start the generator to produce AC power, the AC In setting must be set to Gen1. Therefore, the default value of Gen1 must remain unchanged. <br> In a power system where the two AC sources are available but only one AC source can be used, an external transfer switch becomes necessary. When an external transfer switch is used and an AGS (with a B+ signal connection) is also present, change the AC In setting to Grid1.	Gen1	Gen1, Grid1
