AC Wiring - Specific

The following AC connections are specific to installing the Sine Wave Plus Inverter/chargers in a series-stacked configuration for off-grid and on-grid applications.

Off-Grid AC Wiring for Sine Wave Plus Inverters

Grounding

Neutral Bonds

Inverter to AC Distribution Panel

The following steps are illustrated in Figure 2-4.

To connect the AC wiring for an off-grid application using Sine Wave Plus Inverters:

1.Connect GROUND (green) wires:

a)from the primary earth/ground to the AC distribution panel,

b)from the L1 inverter AC ground bar to the inverter panel ground bar,

c)from the L2 inverter AC ground bar to the inverter panel ground bar.

2.Connect NEUTRAL (white) wires:

a)from the NEUTRAL bus in the inverter panel, to the ground bar in the inverter panel, (Neutral-to-Ground Bond),

b)from the L1 inverter NEUTRAL OUT terminal, to the L2 inverter NEUTRAL 2 terminal. (Inverter-to-inverter neutral bond),

c)from the L2 inverter NEUTRAL OUT terminal to the inverter panel NEUTRAL bus. (Common neutral bond in inverter panel).

3.Connect a HOT wire:

a)(black) from the L1 inverter AC HOT OUTPUT (120 Vac) to the inverter panel L1 terminal,

b)(red) from the L2 inverter AC HOT OUTPUT (120 Vac) to the inverter panel L2 terminal.

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