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).
RS-232 cable
requirements To connect your computer to the GT Inverter, you must use a serial DB9 “straight
through” cable.
