PV Module Selection:
When selecting proper PV modules, please be sure to consider below parameters:
1.
Open circuit Voltage (Voc) of PV modules not exceeds max. PV array open circuit voltage of inverter.
2.
Open circuit Voltage (Voc) of PV modules should be higher than min. battery voltage.
Solar Charging Mode
Max. PV Array Peak Power
5 kWp
Max. PV Array Open Circuit Voltage
450 Vdc
PV Array MPPT Voltage Range
120~430 Vdc
Start-up Voltage
/- 10Vdc
Number of MPPTs
1
Please follow below steps to implement PV module connection:
1.
Remove insulation sleeve 10 mm for positive and negative conductors.
2.
Check correct polarity of connection cable from PV modules and PV input
connectors. Then, connect positive pole (+) of connection cable to positive
pole (+) of PV input connector. Connect negative pole (-) of connection
cable to negative pole (-) of PV input connector.
