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
The following steps are illustrated in Figure 2-4 .
To connect the AC wiring for an off-grid application using Sine Wave Plus
Inverters:
Grounding 1. Connect G
ROUND
(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.
Neutral Bonds 2. Connect N
EUTRAL
(white) wires:
a) from the N
EUTRAL
bus in the inverter panel, to the ground bar in the
inverter panel, (Neutral-to-Ground Bond),
b) from the L1 inverter N
EUTRAL
O
UT
terminal, to the L2 inverter N
EUTRAL
2 terminal. (Inverter-to-inverter neutral bond),
c) from the L2 inverter N
EUTRAL
O
UT
terminal to the inverter panel
N
EUTRAL
bus. (Common neutral bond in inverter panel).
Inverter to AC
Distribution Panel 3. Connect a HOT wire:
a) (black) from the L1 inverter AC H
