Step 3: Remove insulation sleeve for about 7 mm on your positive and negative
wires. We recommend using bootlace ferrules on the wires for optimal
performance.
Step 4: Check polarities of wire connections from PV modules to PV input screw
terminals. Connect your wires as illustrated below. Recommended tool: 4mm blade screwdriver.
WARNING! For safety and efficiency, it's very important to use appropriate cables for PV module connection.
To reduce risk of injury, please use the proper cable size as recommended below.

When selecting proper PV modules, please be sure to consider the following parameters:
1.
Open circuit Voltage (Voc) of PV modules not to exceed 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.
