WARNING: Risk of electric shock
Installation must be performed carefully due to the high battery voltage in series.
CAUTION: Do not place anything between the inverter's flat part, otherwise overheating may occur.
OBSERVE: Do not apply anti-oxidation agents to the terminals before they are properly connected.
OBS: Check that the positive (+) pole is connected to the positive (+) pole and the negative (-) pole to the negative (-) pole before making the final DC connection or closing the DC switch.
IV. AC Input/Output Connection
OBS: Before connecting to the AC power source, install a separate AC switch between the inverter and the AC power source. This ensures that the inverter can be safely disconnected during maintenance and that the AC input is fully protected against overcurrent. The recommended AC breaker specification is 50A.
OBS: There are two terminal blocks labeled "IN" and "OUT". Do NOT interchange input and output.
WARNING: All wiring work must be performed by qualified personnel.
WARNING: It is crucial for system safety and efficient operation that the correct cable is used to connect the AC input. To minimize the risk of personal injury, use the recommended cable size as follows.
Recommended cable requirements for AC cables:
| Model | Cross-section | Torque value |
| 1.5KVA | 12AWG | 1.4~ 1.6Nm |
| 2.5KVA/3.5KVA | 10AWG | 1.4~ 1.6Nm |
| 5.5KVA | 8 AWG | 1.4~ 1.6Nm |
Steps to connect AC input/output:
- Check that the DC breaker is open before connecting AC input/output.
- Remove 10 mm of insulation for six wires. Shorten the L phase cable and N neutral cable by 3 mm.
- Insert the AC input wires according to the polarity indicated on the terminal block and tighten the terminal screws. Ensure you connect the PE protective conductor first.

- Check that the cables are connected correctly.
OBS: Units such as air conditioners require at least 2~3 minutes to restart, as it takes sufficient time to balance the refrigerant gas in the circuits. If a power failure occurs and it is restored in a short time, it will damage the connected appliances. To prevent this type of damage, check with the air conditioner manufacturer before installation if the air conditioner is equipped with a time delay function. Otherwise, this inverter/charger will trigger an overload fault and shut off the output to protect the unit, but may sometimes cause internal damage to the air conditioning system.
V. PV Connection
OBS: Before connecting PV modules, a DC breaker must be installed separately between the inverter and the PV modules.

Notes:
It is best to perform the settings without turning on the inverter (let the LCD screen only display information, without generating power).
Restart the inverter again after the settings are completed.
IV. Battery Balancing
The charge regulator is equipped with a balancing function. It helps to eliminate negative chemical effects such as stratification, a condition where the acid concentration is higher at the bottom of the battery than at the top. Balancing also helps to remove sulfate crystals that may form on the plates. If this condition, known as sulfation, is not controlled, it can reduce the battery's total capacity. Therefore, periodic battery balancing is recommended.
How to use the balancing function:
- Activate the battery balancing function in the LCD monitor settings in software 33.
- You can then use this function on the unit in one of the following ways:
- Set the balancing interval in program 37.
- Activate balancing immediately in program 39.
When should equalization occur
In standby mode, the regulator enters balancing mode when the set time for balancing (battery balancing cycle) has been reached or when balancing is activated immediately.
Figure 70
Charging Time and Equalization Time Limit
During the equalization phase, the controller provides maximum power to charge the battery until the battery voltage reaches the set equalization voltage. Constant voltage charging is then applied to maintain the battery voltage at the equalization voltage. The battery remains in the equalization phase until the set equalization time has been reached.
Illustration 71
If the set equalization time has expired and the battery voltage has not reached the set equalization voltage in the equalization phase, the charge regulator will extend the equalization time until the battery voltage reaches the desired level. If the battery voltage is still lower than the set equalization voltage after the extended equalization time, the charge regulator will interrupt the equalization process and return to standby mode.
