3.5.1 PV Module Selection:
3.5.2 PV Module Wire Connection:
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. start voltage.
3) The PV modules used to connected to this inverter shall be Class A rating certified according
to lEC 61730.
Please follow below steps to implement PV module connection:
1. Remove insulation sleeve 10 mm for positive and negative conductors.
2. Suggest to put bootlace ferrules on the end of positive and negative wires with a proper
crimping tool.
3. Check correct polarity of wire connection 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. Close the switch
and make sure the wires are tightly fixed.
