Wiring the Inverter

Connect the Communications Cable between Inverters in Parallel

WARNING: Shock hazard

If the inverter is already installed and operational, turn OFF the breaker switches in the main utility service panel and the AC/DC Disconnect switch on the inverter wiring box before performing this procedure.

WARNING: Shock hazard

Hazardous voltages may be present when cover is removed. After disconnecting all sources of energy, wait 5 minutes before removing cover.

The following procedure is illustrated in Figure 3-11 on page 3–17. The illustration and procedure assume only two inverters connected in parallel. However, there can be more than two inverters wired in this configuration.

To provide communication between inverters mounted in parallel:

1.Remove the wiring box cover from each unit.

2.On each unit, remove the plug from a 1.9 cm (3/4”) side conduit hole and install appropriate conduit between the two units.

3.Connect the communication cable to any RJ45 port in Inverter #1.

4.Pass the cable through the conduit between Inverter #1 and Inverter #2.

Inside each unit’s wiring box, ensure the communication cable runs horizontally along the flat-bottomed channel formed when the insulation barrier is in place. The cable should run on top of the insulation barrier and out the side conduit hole, avoiding any contact with the AC and DC wiring.

5.Connect the communication cable to any RJ45 port in Inverter #2.

6.For more than two inverters in parallel, continue connecting cable as described above.

7.Insert male network terminators into the empty RJ45 ports in the inverters at the beginning and end of the network. There should be no empty RJ45 ports.
