Please follow below steps to implement battery connection:
1. Assemble battery ring terminal based on recommended battery cable and terminal size.
2. Insert the battery wires flatly into battery connectors of inverter and make sure the bolts are tightened with torque of 2 Nm in clockwise direction. Make sure polarity at both the battery and the inverter/charge is correctly connected and conductors are tightly screwed into the battery terminals. Recommended tool: #2 Pozi Screwdriver.
Installation must be performed with care due to high battery voltage in series.
Before making the final DC connection or closing DC breaker/disconnector, be sure positive (+) must be connected to positive (+) and negative (-) must be connected to negative (-).
How do I connect the AC input/output?
Before connecting to AC input power source, please Install a separate AC breaker between inverter and AC input power source. This will ensure the Inverter can be disconnected during maintenance and fully protected from overcurrent of AC input. The recommended spec of breaker is 32A for 24V system and 63A for 48V system.
There are two terminal blocks with ” IN ” and ” OUT” markings. Please do NOT mis-connect input and output connectors.
All wiring must be performed by qualified personnel.
It’s very important for system safety and efficient operation to use appropriate cable for AC input connection. To reduce risk of injury, please use the proper recommended cable size as below.
| Rated Capacity | Gauge | Torque value |
|---|---|---|
| 2KVA | 14AWG | 08~1.0Nm |
| 3KVA | 12AWG | 1.2~1.6Nm |
| 3.6KVA | 12AWG | 1.2~1.6Nm |
| 5KVA | 10AWG | 1.4~1.6Nm |
| 5.5KVA | 10AWG | 1.4~1.6Nm |

| 8KVA | 8AWG | 1.4~1.6Nm |
| 11KVA | 8AWG | 1.4~1.6Nm |
Please follow below steps to implement AC input/output connection
1. Before making AC input/output connection be sure to open DC protector or disconnector first.
2. Remove insulation sleeve 10mm for six conductors. And shorten phase L and neutral conductor N3 mm.
3. Insert AC input wires according to polarities indicated on terminal block and tighten the terminal screws. Be sure to connect PE protective conductor (ground) first.
Ground (yellow-green)
L-LINE (brown or black)
N-Neutral (blue)
Be sure that AC power source is disconnected before attempting to hardwire it to the unit.
4. Make sure the wires are securely connected.
Appliances such as air conditioner are required at least 2~3 minutes to restart because it’s required to have enough time to balance refrigerant gas inside of circuits. If a power shortage occurs and recovers in a short time, it will cause damage to your connected appliances. To prevent this kind of damage, please check manufacturer of air conditioner if it’s equipped with time-delay function before installation. Otherwise, this inverter/charger will trig overload fault and cut off output to protect your appliance but sometimes it still causes internal damage to the air conditioner.
How do I connect the PV modules (Only apply for the model with solar charger)?
Before connecting to PV modules, please install separately a DC circuit breaker between inverter and PV modules.
All wiring must be performed by a qualified personnel.
It’s very important for system safety and efficient operation to use appropriate cable for PV module connection. To reduce risk of injury, please use the proper recommended cable size as below.
| Typical Amperage | Gauge | Torque Value |
|---|---|---|
| 30A | 12AWG | 1.4~1.6Nm |
When choosing the right PV module, be sure to first consider the following requirements:
The open circuit voltage (Voc) of the PV modules does not exceed the maximum PV array open circuit voltage of the inverter. The maximum supply voltage of the PV modules should be close to the optimal PV access voltage range of the inverter for best performance. If one PV module cannot meet this requirement, it is necessary to connect multiple PV modules in series.

2. Suggest to put bootlace ferrules on the end of positive and negative wires with a proper crimping tool.
3. Fix wire cover to the inverter with supplied screws as shown in below chart.
4. Check correct polarity of wire from PV modules and PV input connectors. Then, connect positive pole(+) of connection wire to positive pole(+) of PV input connector. Connect negative pole (-)of connection wire to negative pole(-) of PV input connector. Screw two wires tightly in clockwise direction. Recommended tool: 4mm blade screwdriver.

Mains power on:
Connect to normal AC power, press the switch, the system will automatically turn on. If you set AC output power priority, after waiting for a period of time, the panel will display AC mode that represents turn on the machine successfully, then will enter the AC mode.
Battery boot:
Connect to battery, press the power-on button to establish a working power source.
The system will automatically turn on, after waiting for a period of time, the panel will display battery mode that represents turn on the machine successfully, then will enter the battery mode.

The cable size used from joint to battery should be X times cable size in the tables above. X indicates the number of inverters connected in parallel.
Regarding AC input and output, please also follow the same principle.
Make sure all output N wires of each inverter must be connected all the time. Otherwise, it will cause inverter fault in error code #72.
Please install the breaker at the battery and AC input side. This will ensure the inverter can be securely disconnected during maintenance and fully protected from over current of battery or AC input. The recommended mounted location of the breakers is shown in the figures in 5-1 and 5-2.
What are the recommended breaker specifications for the battery for each inverter?

How do I apply the Equalization Function?
You must enable battery equalization function in monitoring LCD setting program 30 first. Then, you may apply this function in device by either one of following methods:
1. Setting equalization interval in program 35.
2. Active equalization immediately in program 36.
When to Equalize:
In stage, when the setting equalization interval (battery equalization cycle) is arrived, or equalization is active immediately, the controller will start to enter Equalize stage.
Equalize charging time and timeout:
In Equalize stage, the controller will supply power to charge battery as much as possible until battery voltage raises to battery equalization voltage. Then, constant-voltage regulation is applied to maintain battery voltage at the battery equalization voltage. The battery will remain in the Equalize stage until setting battery equalized time is arrived.
However, in Equalize stage, when battery equalized time is expired and battery voltage doesn’t rise to battery equalization voltage point, the charge controller will extend the battery equalized time until battery voltage achieves battery equalization voltage. If battery voltage is still lower than battery equalization voltage when battery equalized timeout setting is over, the charge controller will stop equalization and return to float stage.
What happens during commissioning in single phase parallel operation?
Step 1: Check the following requirements before commissioning:
Correct wire connection
Ensure all breakers in Line wires of load side are open and each Neutral wires of each unit are connected together.
Step 2: Turn on each unit and set “PAL” in LCD setting program 4 of each unit. And then shut down all units.
It’s necessary to turn off switch when setting LCD program. Otherwise, the setting can not be programmed.
Step 3: Turn on each unit.
Master and slave units are randomly defined.
