Connecting the AC Wiring
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 Figure3-5.
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 mai n br ea ke r in the primary utility breaker box
is switched OFF. Swit ch t his bre ak er ON onl y af ter al l wir ing i s com plete d a s instr ucte d in
the procedures.
Important:
In the United States, the National E lectrical Code (NEC) requires the
inverter to be connected to a dedicated circuit and no other outle ts 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 connec ted to the utility grid. The circuit breakers that are used in
the main panel that feed th e in verter circuit must be for back-fed operation and labeled as
such.
Important:
Neutral conductor wiring is not required in this installation.
