PV Module Selection:
When selecting proper PV modules, please be sure to consider the following parameters:
1.
Open circuit Voltage (Voc) of PV modules not to exceeds maximum PV array open circuit voltage of the
inverter.
2.
Open circuit Voltage (Voc) of PV modules should be higher than the start-up voltage.

PV Module Wire Connection
Please take the following to implement PV module connection:
1.
Remove insulation sleeve for about 7 mm on your positive and negative
wires.
2.
We recommend using bootlace ferrules on the wires for optimal
performance.
3.
Check polarities of wire connections from PV modules to PV input screw
terminals. Connect your wires as illustrated below.
Recommended tool: 4mm blade screwdriver
