Install AC Output Wiring to the Inverter AC Distribution Panel

An inverter AC distribution panel (referred to here as the inverter panel)
and AC conduit must be installed before AC output wiring is c onnect ed to
the inverter. The inverter panel is a subpanel.
Install the inverter AC distr ibution 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 to the inverter panel and the inverter.
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.
CAUTION: Equipment Damage
Verify that only one neutral/groun d bond e xist s in the sys tem. Havin g more th an
one neutral to ground bond in a system may create a shock hazard and cause
some sensitive equipment to malfunction.
On-Grid systems always have a ground-to-neutral bond provided by the utility
meter or service entrance, therefore, you do not need a ground to neutral bond
made in the inverter panel.
See “Bonding the Grounding System” on page2–10 for details.
Important:
Under no circumstances should utility power or generator power
energize the inverter pane l d irectly while the inverter als o energizes the inverter
panel.
