C250 System Installation and Operation
The Enphase C250 Microinverter System
Used with a transformer, the C250 Microinverter System meets the needs of large commercial
installations where power distribution is 480Y/277V or medium voltage (MV).
With the fourth generation Enphase Microinverters, the DC circuit within the microinverter is isolated and
insulated from ground. Ground fault protection (GFP) is integrated into the microinverter. Because of this,
the microinverters do not require a GEC. As a result, it takes less time to install than other microinverters,
saves money, and increases safety. Fourth generation microinverters include the C250.
This integrated system maximizes energy harvest, increases system reliability, and simplifies design,
installation and management.
