Electrical Connection

6.1

PV connection

This inverter can be connected with 4-strings of PV modules for 12kW. Select PV modules with excellent
function and reliable quality. Open-circuit voltage of module arrays connected in series should be <max,
temperature adjusted DC input voltage. Operating voltage should be conformed to MPPT voltage range.
Step1. Wiring.
1.1 Use 10 AWG wire to connect with ferrules.
1.2 Remove 18mm of insulation from the end of the wire.
Step2. Feed the PV cables through the PV port, and connect the PV cables to the PV terminals.
6.2

Grid Connection (GEN connection)

Step1. Check the grid voltage.
1.1 Check the grid voltage and compare to acceptable voltage ranges (Please refer to
technical data).
1.2 Disconnect the circuit board, and secure against re-connection.
Step2. Grid cables
