Selling First (Generation limit control): This Mode allows hybrid inverter to sell back any excess power produced by the solar panels to the grid. If time of use is active, the battery energy also can be sold into grid. The PV energy will be used to power the load and charge the battery and then excess energy will flow to grid. Power source priority for the load is as follows: 1. Solar Panels, 2. Grid, 3. Batteries (until programmable % discharge is reached).

Zero Export To Load: Hybrid inverter will only provide power to the backup load connected. The hybrid inverter will neither provide power to the home load nor sell power to grid. The built-in CT will detect power flowing back to the grid and will reduce the power of the inverter only to supply the local load and charge the battery.

Zero Export To CT (Export limit control): Hybrid inverter will not only provide power to the backup load connected but also give power to the home load connected. If PV power and battery power is insufficient, it will take grid energy as supplement. The hybrid inverter will not sell power to grid. In this mode, a CT is needed. The installation method of the CT please refer to chapter 3.6 CT Connection. The external CT will detect power flowing back to the grid and will reduce the power of the inverter only to supply the local load, charge battery and home load.

Other Definitions related to Work Modes:

– Solar Sell: For “Zero export to load” or “Zero export to CT”. When active, surplus energy can be sold back to grid. PV Power source priority: load consumption, charge battery, then feed into grid.

– Max. sell power: Soft export. Allowed maximum output power to flow to grid.

– Zero-export Power: For zero-export mode, sets grid output power. Recommended: 20-100W to prevent feeding to grid. Hard export: if exceeded, inverter stops immediately.

– Energy Pattern: PV Power source priority.

– Batt First: PV power first charges battery, then powers load. Grid supplements if PV is insufficient.

– Load First: PV power first powers load, then charges battery. Grid supplements if PV is insufficient.

– Max Solar Power: Allowed maximum DC input power.

– Grid Peak-shaving: When active, grid output power is limited. If load exceeds limit, PV and battery supplement. If still insufficient, grid power increases.

Note on Limit Control: Customer can only use export limit control function by CT or meter.

– Droop f: percentage of nominal power per Hz. For example, “Start freq f > 50.2Hz, Stop freq f < 50.2, Droop f=40%PE/Hz" means when the grid frequency reaches 50.2Hz, the inverter will decrease its active power at Droop f of 40%. And then when grid system frequency is less than 50.2Hz, the inverter will stop decreasing output power.

For the detailed setup values, please follow the local grid code.

– V(W): It is used to adjust the inverter active power according to the set grid voltage.

– V(Q): It is used to adjust the inverter reactive power according to the set grid voltage. This function is used to adjust inverter output power (active power and reactive power) when grid voltage changes.

– Lock-in/Pn 5%: When the inverter active power is less than 5% rated power, the VQ mode will not take effect.

– Lock-out/Pn 20%: If the inverter active power is increasing from 5% to 20% rated power, the VQ mode will take effect again.

For example: V2=110%, P2=20%. When the grid voltage reaches 110% times of rated grid voltage, inverter output power will reduce its active output power to 20% rated power.

For example: V1=90%, Q1=44%. When the grid voltage reaches 90% times of rated grid voltage, inverter output power will output 44% reactive output power.

For the detailed setup values, please follow the local grid code.

– P(Q): It is used to adjust the inverter reactive power according to the set active power.

– P(PF): It is used to adjust the inverter PF according to the set active power. For the detailed setup values, please follow the local grid code.

– Lock-in/Pn 50%: When the inverter output active power is less then 50% rated power, it won’t enter the P(PF) mode.

– Lock-out/Pn 50%: When the inverter output active power is higher then 50% rated power, it will enter the P(PF) mode.

– Note: only when the grid voltage is equal to or higher than 1.05 times of rated grid voltage, then the P(PF) mode will take effect.

– Generator Input Rated Power: Allowed Max. power from diesel generator.

– GEN connect to Grid input: Connect the diesel generator to the grid input port.

– SmartLoad Output: This mode utilizes the Gen input connection as an output which only receives power when the battery SOC and PV power is above a user programmable threshold. Example: Power=500W, ON: 100%, OFF=95%: When the PV power exceeds 500W, and battery bank SOC reaches 100%, Smart Load Port will switch on automatically and power the load connected. When the battery bank SOC < 95% or PV power < 500W, the Smart Load Port will switch off automatically.

– Smart Load OFF Batt: Battery SOC at which the Smart load will switch off.

– Smart Load ON Batt: Battery SOC at which the Smart load will switch on. Also, the PV input power should exceed the setting value (Power) simultaneously.

– On Grid always on: When selected, the smart load will switch on when the grid is present.

– Off grid immediately off: The smart load will stop working immediately when the grid is disconnected if this item is active.

– Micro Inv Input: To use the Generator input port as a micro-inverter on grid inverter input (AC coupled). This feature also works with “Grid-Tied” inverters.

– Micro Inv Input OFF: When battery SOC exceeds setting value, Microinverter or grid-tied inverter will shut down.

– Micro Inv Input ON: When battery SOC is lower than setting value, Microinverter or grid-tied inverter will start to work.

– AC Couple Fre High: If choosing “Micro Inv input”, as the battery SOC reaches gradually setting value (OFF), the microinverter output power will decrease linearly. When battery SOC equals setting value (OFF), system frequency becomes AC couple Fre high and Microinverter stops. This stops exporting power from the microinverter to the grid.

– Note: Micro Inv Input OFF and ON is valid for some certain FW version only.

– AC couple on load side: Connecting output of on-grid inverter to the load port of hybrid inverter. Hybrid inverter won’t show load power correctly.

– BMS_Err_Stop: When active, if the battery BMS fails to communicate with inverter, the inverter will stop working and report fault.

– Signal ISLAND MODE: When “signal island mode” is checked and inverter connects to grid, ATS port voltage is 0. When checked and inverter disconnects from grid, ATS port outputs 230Vac. With an outside NO type relay, it can realize N and PE disconnection or bond.

– Wind Turbine Settings (DC1/DC2): Various voltage and amperage settings (V1-V12).

– Ex_Meter For CT: For three-phase system with CHNT three-phase meter (DTSU666), select the phase where hybrid inverter is connected (e.g., A Phase).

– Meter Select: Select the corresponding meter type (CHNT-3P, CHNT-1P, Eastron-3P, Eastron-1P).

– Grid Side INV Meter2: If a string inverter AC couples at grid/load side with a meter, hybrid LCD shows string inverter output on PV icon. Ensure meter communication.

– ATS: Related to ATS port voltage. Better in “uncheck” position.

– Export power limiter: Sets allowed maximum output power to flow to grid.

– Import power limiter: When active, grid output power is limited. Priority lower than “grid peak shaving”.

– Low Noise Mode: Inverter works in “low noise mode”.

– Low Power Mode

– MPPT Multi-Point Scanning: Checks if PV I/V is at Max Power Point. If not, adjusts I/V.

The 1st priority power of the system is always the PV power, then 2nd and 3rd priority power will be the battery bank or grid according to the settings. The last power backup will be the Generator if it is available.

If any of the fault messages listed in Table 7-1 of the PDF appear on your inverter and the fault has not been removed after restarting, please contact your local dealer or service center. You need to have the following information ready:

1. Inverter serial number;

2. Distributor or service center of the inverter;

3. On-grid power generation date;

4. The problem description (including the fault code and indicator status displayed on the LCD) is as detailed as possible.

5. Your contact information.

Usually place inverter in the packing box with tape sealing. If the inverter cannot reoccupy the original packing, you can choose a cheap carton for packaging. Carton requirements must meet the size of the inverter and can support inverter machine overall weight.

When moving the series frequency converter, please note: handle with care, do not touch the inverter, put as flat as possible.

Do not dispose of inverter together with household waste. Please accordance with the disposal regulations for electronic waste which apply at the installation site at that time. Ensure that the old unit and, where applicable, any accessories are disposed of in a proper manner.

This port is used to connect the energy meter.
