IQ System Controller 3
The Enphase IQ System Controller 3 connects the home to grid power, the IQ Battery
system, and solar PV. It provides microgrid interconnect 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 and storage installations by
providing a consistent, pre-wired solution for residential applications.
