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 connected to
the inverter. The inverter panel is a sub-panel.
Install the Inverter AC Distribution Panel and conduit as follows:
1. Determine the location for the Inverter AC Distribution Panel
(i.e., the sub-panel or inverter 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 sub-panel.
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
Verify that only one neutral/ground bond exists in the system.
Having more than 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 page 2–9 for details.
Important: Under no circumstances should utility power or generator
power energize the inverter panel directly while the inverter also
energizes the inverter panel.
