The Enphase IQ System Controller 3 is a smart controller used in Enphase solar and battery systems. It manages the connection between solar panels, batteries, your home, and the utility grid. During a power outage, it automatically disconnects the home from the grid and switches to backup power. It works with Enphase IQ8 microinverters and IQ Batteries to provide reliable energy management. The system supports whole-home or partial-home backup and helps maintain power during outages.
