AC Wiring to the Inverter Load Sub-Panel
An inverter load sub-panel (also known as an inverter AC distribution panel) and
AC conduit must be installed before AC wiring is connected to the inverter.
To install the inverter load sub-panel and conduit:
1. Determine the location for the inverter load sub-panel, and install it
according to the manufacturer’s directions.
2. Install an AC conduit between the Xantrex XW Inverter/Charger and the
inverter load sub-panel.
3. Determine which circuits the inverter will power, and install the appropriate
circuit breakers into the inverter panel.
4. For on-grid systems:
a) Disconnect all power to the main utility panel.
b) Determine which circuits will be supplied by the inverter(s) and remove
their wires from the main panel.
c) Reroute these wires to the new inverter load sub-panel.
5. Remove unused breakers from utility panel.
6. Install a 60-amp maximum (disconnect) main circuit breaker in the inverter
panel. Later, this will be wired to the inverter’s output.
WARNING: Shock Hazard
Before making any electrical connections, make sure all AC and DC disconnect
devices are in the OPEN (disconnect) position.
CAUTION: Damage to the Inverter
The inverter’s AC output must never be wired to the utility or generator output.
This will cause severe damage to the inverter which is not covered under
warranty.
