The SolarCity H6 inverter can only be tied to the 240V, 60Hz North American split single-
phase public grid. Configuration can be performed using either the built-in LCD display or a
remote connection (see
“Menu Structure” on page 77
) to specify settings such as voltage,
frequency, and trip times per local regulations.
IEEE 1547 specifies the following default operating ranges
• Voltage range for 240V: 211V (-12%) to 264V (+10%)
• Frequency range for 60Hz: 59.3 to 60.5Hz
One can determine potential voltage loss in AC wiring based on both the wiring cross section
and distance between the inverter and the grid interconnection. In general, you should
select wire size and length to limit voltage losses to between 1% and 2%.
CAUTION: THE SOLARCITY H6 INVERTER IS NOT COMPATIBLE WITH 208V
OR 277V GRIDS.
Note: These values are subject to change per local requirements. Please
refer to the SolarCity H6 Inverter Datasheet for adjustable ratings.
CAUTION: ALL WIRING MUST BE SIZED TO AT LEAST 167°C (75°F) PER NEC
TABLE 310.15(B)(16) AND RATED TO AT LEAST 194°F (90°).
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.
