Enphase IQ System Controller 3 INT

The IQ System Controller 3 INT connects the home to the public power grid, the IQ Battery 5P storage system, and the IQ7 or IQ8 Series Microinverter circuits. The system provides ATS functionality (Automatic Transfer Switch) that automatically detects and transfers the home’s energy system from grid power to backup power in the event of a power outage. It consolidates interconnection equipment, IQ Gateway Metered, and IQ Relay functionality into a single enclosure, streamlining off-grid capabilities of PV and storage installations with a consistent, pre-wired solution, including CTs.
