If a generator is used as a backup for the utility, then an AC transfer switch must
be added to provide a means to switch the generator power to the inverter's
inputs. The generator can be used during extended outages to recharge the
batteries and provide pass-through power for the loads. Start and stop the
generator manually using the generator's pull-cord, ON/OFF switch, etc.
See Figure 3-15 for a basic 120 Vac utility/generator block diagram.
1. Connect a (green) ground wire between the generator's GROUND terminal
and the GROUND terminal in the AC transfer switch.
2. Connect a (white) neutral wire between the generator's NEUTRAL terminal
and the NEUTRAL bus in the AC transfer switch.
3. Connect a (black) HOT wire between the generator's HOT OUT terminal and
the generator's HOT contact in the AC transfer switch.
1. Connect a (green) wire between the GROUND terminal in the main utility
breaker box and the GROUND terminal in the AC transfer switch.
2. Connect a (white) wire between the NEUTRAL bus in the main utility breaker
box and the NEUTRAL bus in the AC transfer switch.
3. Connect a (black) wire between the inverter circuit breaker in the main utility
breaker box and the utility HOT contact in the AC transfer switch.
1. Connect a (green) wire between the GROUND terminal in the AC transfer
switch and the inverter's AC GROUND terminal.
2. Connect a (white) wire between the NEUTRAL terminal in the AC transfer
switch and the inverter's NEUTRAL IN terminal.
3. Connect a (black) wire between the COMMON terminal in the AC transfer
switch and the inverter's HOT IN terminal.
4. Torque all wires 16 in/lb.
1. Connect a (green) wire between the inverter's AC GROUND terminal and the
GROUND terminal in the sub-panel.
2. Connect a (white) wire between the inverter's NEUTRAL OUTPUT terminal
and the NEUTRAL bus in the sub-panel.
3. Connect a (black) wire between the inverter's terminal labeled AC HOT
OUTPUT and the sub-panel's INPUT circuit breaker.
4. Torque all inverter terminal block connections to 16 in/lb. Refer to the sub-
panel manufacturer's specifications for wire torques.
5. Recheck all connections.
