Wiring the Inverter
Connecting Inverters in Parallel
GT Inverters can be connected in a parallel configuration for larger PV array systems. In this configuration, separate solar arrays are required for each GT Inverter unit. The output of each GT Inverter feeds a separate
DC and AC Wiring for Inverters in Parallel

Connecting AC wiring
The following procedures are illustrated in Figure
If there will be more than one PV string, label the positive and negative wire pairs appropriately (for example: PV 1, PV 2).
To wire the PV array to GT Inverters in parallel:
1.Install the DC conduit from the PV strings to the GT Inverter wiring boxes, through appropriate knockout holes. Metal conduit is highly recommended.
2.Remove the wiring box cover (see page
3.Route the wires from the PV string(s) through the conduit and into the wiring box.
4.Connect the DC Ground from each PV array to the GND bar in the wiring box.
5.Follow the instructions on page
6.Ensure all connections are correctly wired and properly torqued according to values shown in Table
To wire the main utility service panel to the GT Inverters in parallel:
1.Run conduit from the main utility service panel to the wiring boxes of the GT Inverters.
2.Follow the instructions on page
3.Ensure all connections are correctly wired and properly torqued according to values shown in Table
