Wiring the Inverter

Connecting the AC Wiring

WARNING: Shock hazard

Before wiring the GT Inverter, ensure the main breaker in the primary utility breaker box is switched OFF. Switch this breaker ON only after all wiring is completed as instructed in the procedures.

The GT Inverter can be connected to a single bi-directional meter, or to dual meters, where one meter indicates power used and the second meter indicates power sold (power supplied back to the utility). Consult the local utility to determine the proper components to install, and obtain any permits required prior to installation.

Ensure all connections are correctly wired and properly torqued to a maximum 16 in-lb (1.8 Nm).

The AC wiring procedure is illustrated in Figure 3-9.

Important: The neutral conductor must be attached to the inverter in all cases. The neutral conductor is used for phase-to-neutral voltage sensing only and is not a current carrying conductor. This conductor is not bonded to ground in the inverter.
