AC Wiring to the Inverter AC Distribution Panel
An inverter AC distribution panel (also known as a sub-panel or inverter load
panel) and AC conduit must be installed before AC wiring is connected to
the inverter.
Install the inverter AC distribution panel and conduit as follows:
1. Determine the location for the inverter AC distribution panel and install it
according to the manufacturer’s directions.
2. Install an AC conduit between the Xantrex XW Power Distribution Panel and
the inverter AC distribution 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 backed by the inverter(s) and remove
their wires from the main panel.
c) Reroute these wires to the new inverter subpanel.
5. Remove unused breakers from utility panel. It is now safe to re-energize the
main utility panel.
6. Install a 60-amp maximum (disconnect) main circuit breaker in the inverter
panel. This will later be wired to the inverter’s output.
WARNING: Shock Hazard
Before making any electrical connections, ensure both the AC and DC
disconnect devices are in the OPEN (disconnect) position.
CAUTION: Equipment Damage
Verify that only one neutral/ground bond exists in the system. Having more than
one neutral to ground bond in a system violates local electrical codes, may
create a shock or fire hazard, and may cause some sensitive equipment to
malfunction.
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.
