Wiring the Inverter

Connecting Network Cable between Inverters

This procedure assumes only two inverters are installed. However, there can be up to ten inverters wired in this configuration.

To provide communication between multiple inverters:

1. Remove the comm port covers from all inverters. See Figure 3-10.

1.Connect the network cable to an empty RJ45 port in Inverter #1.

2.Pass the cable through the cable clamp on the comm port cover of Inverter #1.

3.Pass the cable between Inverter #1 and Inverter #2, securing the cable appropriately.

4.Pass the cable through the cable clamp on the comm port cover of Inverter #2.

5.Connect the network cable to an empty RJ45 port in Inverter #2.

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

7.If not already installed, insert male network terminators into the empty RJ45 ports in the inverters at the beginning and end of the network.

After connecting network cables and inserting terminators, there should be no empty RJ45 ports in any connected inverter.

8.After completing network cabling, replace the comm port covers on all units.

Communications Wiring for Monitoring a Single Inverter

 

You can view GT Inverter operational data on a personal computer using the

 

Xantrex GT Solar Inverter Viewer (“GT-View”), which you can download free of

 

charge at www.xantrex.com.

 

To use GT-View, you must connect your computer’s serial port to the GT Inverter

 

RS-232 port (see Figure 3-8).
