12.1 Output AC Specifications
The inverters are designed to feed power into a standard 60Hz, three-phase AC utility service
provided within a facility with a rating of not less than the rating of the inverter(s) connected to
it.
The inverter is designed to work with the range of AC voltages for a three-phase service defined
by IEEE 1547-2003 and ANSI C84.1.
