Chapter 1 - Welcome

• Wiring Box – with cover (10): This is the cover for the wiring box compartment. The inside

of the wiring box cover includes a label with a wiring diagram. All of the following must be

shut off before removing the cover:

- Breaker(s) in the Backup Load Panel

- Back-feed breaker in the main panel

- DC Disconnect Switch (11)

See

“Wiring Box Cover” on page 59

• DC Disconnect Switch (11): This switch allows DC power from both the PV array and

battery pack to be cut off from the inverter. The DC Disconnect is lockable in the OFF

position. See

“DC Disconnect Switch” on page 25

• AC Bypass Switch (12): By default, when set to the INV position, the AC Bypass Switch

connects backup loads to the utility grid via the SolarCity H6 inverter; however, you can

bypass the inverter and directly connect protected loads to the utility grid during

service/maintenance by switching to the BYP position. There is no OFF position for this

switch, so for AC grid isolation, the back-feed breaker in the main panel must be

disconnected. See

“AC Bypass Switch” on page 26

• Conduit plugs (13): The SolarCity H6 inverter includes a single 1” conduit opening, six (6)

3/4” conduit openings, and a single ½” conduit opening. Each conduit opening includes a

watertight rubber or plastic plug that must be removed before installing conduit fittings.

Conduit fittings must be watertight. See

“Conduit Plugs and Fittings” on page 61

• ZigBee antenna (14): The ZigBee antenna uses the 2.4GHz to 3.5GHz frequency range and

connects to the SolarCity H6 inverter using the standard SolarCity RP plug.

Figure 3-1

shows the antenna mounting only; the antenna itself is not shown. The antenna is rated

for use in both indoor and outdoor installations. See

“ZigBee & Gateway” on page 69

• Inverter Mounting Bracket (not shown): The Inverter Mounting Bracket is used to secure

the SolarCity H6 inverter to the wall. See

“Inverter Mounting Bracket” on page 22
