The Enphase IQ System Controller 3 is the backup management hub for Enphase IQ8 microinverter systems. Unlike the earlier IQ System Controller 2, the Controller 3 leverages the IQ8's grid-forming capability to provide solar-powered backup — meaning the battery charges from solar even during an outage, extending backup runtime indefinitely on sunny days.
