Connecting the AC Wiring

WARNING: Shock hazard

AC utility wiring to the GT Inverter unit is performed directly at the main breaker panel. This should be done only by a qualified installer or electrician.

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.

Important: In the United States, the National Electrical Code (NEC) requires the inverter to be connected to a dedicated circuit and no other outlets or devices may be connected to this circuit. The NEC also imposes limitations on the size of the inverter and the manner in which it is connected to the utility grid. The circuit breakers that are used in the main panel that feed the inverter circuit must be for back-fed operation and labeled as such.

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 with the local utility to determine the proper components to install, and obtain any permits required prior to installation.

The following procedure is illustrated in Figure 3-5.

Important: Neutral conductor wiring is not required in this installation.
