Enphase IQ System Controller 3, 200A Solar + Battery Backup Transfer Switch (SC200D111C240US01)
Seamless Solar and Battery Backup for the Whole Home
The Enphase IQ System Controller 3 (SC200D111C240US01) connects your home to grid power, IQ Batteries, and Enphase microinverter solar. As the microgrid interconnection device (MID), it automatically detects a grid outage and moves the home to backup power, then reconnects on its own when the grid returns.
Picture a winter storm taking down the lines on your street. Your neighbors reach for flashlights, but your furnace fan keeps running and the lights stay on as the controller islands your system and runs the home on solar and battery power. Enphase recommends the IQ System Controller 3 for all new installs using IQ8 Series Microinverters.
Note: This model does NOT support generator integration. If you need a generator in your backup system, choose the IQ System Controller 3G.
