• High Voltage: 8-12AWG
• Communications (Set 1): 16-24AWG (see “Battery Pack Interface” on page 31 )
The DC Disconnect Switch (see “DC Disconnect Switch” on page 25 ) contained within the
SolarCity H6 inverter disconnects both the PV array and the battery pack at the same time. In
addition, some battery packs may have a separate disconnect switch that is either
integrated into the battery pack or installed close to the battery pack externally.
3.7.3 - Back-up Electrical Panel
The back-up electrical panel should generally be installed close to the main electrical panel.
Loads requiring backup functionality (the protected home loads) are moved from the main
electrical panel to the back-up electrical panel.
Each of the split phases (BL1-BN and BL2-BN) of the split single-phase AC output functions
independently, and the protected home loads should be accordingly balanced between the
split single phases. Select only loads that will not cause the circuit breakers to trip from
Note: NEC 310.15 specifies the wiring AWG to use.
Note: These values are subject to change. Please refer to the SolarCity H6
Inverter Datasheet for updated values.
SHOCK HAZARD: VERIFY THAT ALL EXTERNAL CABLES ARE PROPERLY
PROTECTED. INSUFFICIENT PROTECTION ON HIGH-VOLTAGE DC WIRES
CAN CAUSE DEATH OR SERIOUS INJURY FROM ELECTROCUTION.
SHOCK HAZARD: DO NOT CONNECT THE INTERNAL HIGH-VOLTAGE
