
The AC input (generator or utility grid) must be a single-phase source of the proper voltage and frequency.

When wiring the AC source to the inverters, local codes may require the inverter circuits to be located at the
opposite end of the panel from the main circuit breaker. This prevents overloading of the AC bus.

NOTES:
1. Neutral (common) conductor may
be connected from only one inverter
neutral terminal to a common bus bar
in the AC conduit box.
2. Colors shown here may be different
from wiring standards.
