Generator AC Wiring to Series-stacked Inverters

With a generator disconnect switch

The following wiring diagrams show the AC wiring from an AC generator to the inverters.

The following procedures are illustrated in Figure 2-6.

Important: Ensure that an inverter-to-inverter neutral bond is in place before proceeding with this procedure.

To install the AC wiring from a generator with a (GDS):

1.Connect GROUND (green) wires:

a)from the generator GROUND to the generator disconnect switch GROUND terminal,

b)from the generator disconnect switch GROUND to the AC Ground bar in the utility panel*.

2.Connect NEUTRAL (white) wires:

a)from the generator NEUTRAL to the GDS NEUTRAL terminal,

b)from the generator disconnect switch NEUTRAL to the L1 INVERTER NEUTRAL 2 terminal.

3.Connect HOT (L1- black) wires:

a)from the generator L1 GEN HOT OUT to the GDS L1 HOT terminal,

b)from the generator disconnect switch L1 HOT to the L1 INVERTER AC2 GEN terminal.

4.Connect HOT (L2 - red) wires:

a)from the generator L2 HOT OUT to the generator disconnect switch L2 HOT terminal,

b)from the generator disconnect switch L2 HOT to the L2 INVERTER AC2 GEN terminal.

5.Torque all inverter terminal block connections to 25 inch-pounds.

Important: *If this is an off-grid installation, then all connections that would normally go to the Main Utility Panel should be routed to the AD Distribution Panel instead.
