Install Generator Wiring to the Inverter
Generator
Disconnect Switch
(If used)
Having a generator disconnect switch between the inverter and the
generator is strongly recommended. This will provide overcurrent
protection for the wiring between the inverter and the generator. It also
prevents the generator wiring inside the inverter from becoming
energized while the inverter is being serviced.
To install a generator disconnect switch:
◆ Determine a location for the generator disconnect switch and install it
according to the manufacturer’s directions.
A conventional load center (breaker box) can be used to distribute the
power from the generator to the inverter input and to loads that cannot
be powered by the inverter. Loads such as air conditioners, large well
pumps, and arc welders are typically better suited to run directly from
the generator than to be “passed through” the inverter transfer relay. If
the load is too big for the inverter to operate from battery power, do
not install the load in the inverter powered electrical panel.
A good location for a generator disconnect switch is adjacent to the
inverter.
WARNING: Shock Hazard
Before connecting any AC wiring, ensure that there is no DC energy accessible
by the inverter by opening the DC disconnect switch.
Important: Be sure that the circuit breaker(s) within the switch are
appropriately sized to protect the wires between the inverter and the generator.
This is based on the generator’s output capacity.
