Basic 120 Vac Generator Hookup (Off-Grid applications only)

NOTE: The ground and neutral
must be bonded at one
place, and only one place, in
the system. If the generator
is the main source of power,
(i.e., no utility grid power)
then the neutral and ground
connections are bonded at
the generator. If the
generator is acting as a
backup for the utility grid,
then the bond should be at
the main utility breaker box.
In this case, ensure that no
bond exists at the generator
output.

1. Connect the ground wire on the generator to the GROUND terminal on the
inverter.
2. Connect the generator neutral wire to the NEUTRAL terminal on the inverter.
3. Connect the generator HOT wire to the HOT input on the inverter.
4. Bond the neutral to the ground on the output of the generator (only if used in
non-utility installations) or in the main utility breaker box (not both).
5. Drive a ground rod 6–8 feet (1.8 - 2.4 meters) into the ground and connect the
generator's ground to the ground rod.
6. Start the generator and check for proper operation of the inverter (i.e., the
inverter transfers from battery to generator power).
