Enphase IQ System Controller 2 > Connects home to solar, grid and IQ Battery System - IQ System

The Enphase IQ System Controller 2 connects the home to grid power, the IQ Battery system, and solar PV. It 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 and storage installations by providing a consistent, pre-wired solution for residential applications.

Note: Enphase Rapid Shutdown Switch (EN-EP200G-NA-02-RSD) is required when an IQ8 microinverter is installed with an IQ System Controller 2; Enphase Rapid Shutdown Switch sold separately.
