Connect to Solar Panel 

CAUTION: 

Before connecting to PV modules, please install 

separately 

a DC circuit breaker 

between inverter and PV modules. 

WARNING! 

All wiring must be performed by a qualified personnel. 

WARNING! 

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.

Step 1-

 Connect one cable to the positive (+) pole of solar panel and solar charger positive 

(+) terminal.   

Step 2- 

Connect the other cable to the negative (-) pole of solar panel and solar charger 

negative (-) terminal. 

Step 3- 

Check the solar charging indicator. If the LED lights up, it means that batteries are 

charged by solar power. When the batteries are fully charged or there is no solar power 
available, the LED will be off. (See following chart) 

 

PV Module Selection:

 

When selecting proper PV modules, please be sure to consider below requirements 
first:   

1.

 

Open circuit Voltage (Voc) of PV modules not exceeds max. PV array open circuit 
voltage of inverter.

60Vdc 

 
2.    Max. Power Voltage (Vmpp) of PV modules should be close to best Vmp of 

inverter or within Vmp range to get best performance. If one PV module cannot 

meet this requirement, it’s necessary to have several PV modules in series 
connection. Refer to below table.

Take 1.2KVA inverter as an example to select proper PV modules. After considering 

Voc of PV module not exceeds 45Vdc and max. Vmpp of PV module close to 15Vdc or 
within 15Vdc ~ 18Vdc, we can choose PV module with below specification.

Maximum PV module numbers in Series: 1 
PV module numbers in Parallel: 10 

Total PV module numbers: 1 x 10 = 10

 

 

Take 2.4KVA inverter as an example to select proper PV module. After considering 
Voc of PV module not exceed 60Vdc and max. Vmpp of PV module close to 30Vdc or 

within 30Vdc ~ 32Vdc, we can choose PV module with below specification.
