IQ System Controller 3
The Enphase IQ System Controller 3 connects the home to grid power, IQ Batteries, and solar PV with Microinverters.
Use IQ System Controller 3 for all new installs using IQ8 Series Microinverters.
IQ System Controller 3 provides microgrid interconnection device (MID) functionality by automatically detecting and seamlessly transitioning the home energy system from grid power to backup power in the event of a grid failure. It consolidates interconnection equipment into a single enclosure and streamlines grid-independent capabilities of PV, storage by providing a consistent, pre-wired solution for residential applications.
