Communications Wiring for Inverters in Parallel

Communications wiring between GT Inverters mounted in parallel allows information about each inverter and its associated PV array to be communicated between all of the inverters in the system. Information about the entire system can be displayed on any inverter LCD in the system.

For example, in a two-inverter system, if inverter #1 is producing 1500 W and inverter #2 is producing 2000 W, both inverters display a total system power of 3500 W. The cumulative energy produced by both inverters that day is also displayed.

You can still view information for an individual inverter in a system. See “To view unit-specific screens in a multiple unit system:” on page 5–5.

Without communications wiring each inverter in a system will only display information pertinent to the unit and its associated PV array.

Xanbus Network Technology

GT Inverters use Xanbus technology to communicate with other inverters in parallel. Communications wiring between inverters is laid out in a “daisy chain” pattern, each device on the network linked together with separate lengths of cable, as shown in Figure 3-7.

For more information on installing a Xanbus network, see the Xanbus System

Installation Guide, available at www.xantrex.com.

CAUTION: Equipment damage

Connect only Xanbus-enabled devices.

Although the cabling and connectors used in this network system are the same as ethernet connectors, this network is not an ethernet system. Equipment damage may result from attempting to connect Xanbus to different systems.
