Enphase IQ System Controller 3 INT

The IQ System Controller 3 INT is only required if backup is needed and it connects the home to grid power, the IQ Batteries, and solar PV with microinverters. 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.

The Enphase IQ System Controller 3 INT consolidates interconnection equipment and the communication gateway into a single enclosure and streamlines the grid-independent capabilities of PV and storage installations by providing a consistent, pre-wired solution for residential or domestic applications.
