5.8 - AC Voltage
This section describes how to wire the AC grid and backup panel connections.
5.8.1 - Output to Grid
To connect the AC grid wiring to the SolarCityH6 inverter:
1. Run and connect one (1) 1” conduit to the SolarCity H6 inverter for the AC output wires to
the main panel using a watertight conduit fitting, as described in
“Conduit Plugs and
Fittings” on page 61
.
2. Pull the wires from the main electrical panel through the conduit to the inverter, leaving
at least 6” (152mm) of exposed wire to ensure adequate strain relief and wire end strip
length. The wiring must comply with the requirements listed in
“Main Electrical Panel” on
page 41
. If you are installing a Fireman Switch (see
“Fireman Switch” on page 71
), then
these wires will usually share the same conduit.
3. Use the procedure described in
“Using the Spring Clamp Connectors” on page 62
to
connect the AC output wires to the L1, L2, N, and ground connectors in the SolarCity H6
inverter as described in
“AC Grid Point of Interconnection” on page 34
and
“Main
Electrical Panel” on page 41
:
- Connect the black L1 wire to the “L1” connector.
- Connect the white Neutral wire to the “N” screw connector.
SHOCK HAZARD: ENSURE THAT NO LIVE VOLTAGES ARE PRESENT ON PV
INPUT AND AC OUTPUT CIRCUITS, AND VERIFY THAT THE DC
DISCONNECT, AC DISCONNECT, AND DEDICATED AC BRANCH CIRCUIT
BREAKER ARE IN THE “OFF” POSITION BEFORE INSTALLING THE
SOLARCITY H6 INVERTER.
SHOCK HAZARD: VERIFY THAT THE DEDICATED 2-POLE 240 VAC BACK-
FEED CIRCUIT BREAKER IN THE MAIN ELECTRICAL PANEL IS TURNED OFF.
Note: The AC output (neutral) is not bonded to ground in the SolarCity H6
inverter.
Note: Stranded copper wire should be checked to ensure that all strands
go into the connector opening. Do not use fine-stranded wire.
