IQ System Controller 4
The IQ System Controller 4 is an all-in-one Microgrid Interconnect Device (MID). It connects the home to the utility grid, the IQ Combiner 6C, and load panels. The MID automatically senses grid outages and switches the home to backup power. It also supports standby generator integration on a dedicated breaker spot. Choose IQ System Controller 4 as an option whenever a utility won't approve the IQ Meter Collar.
The IQ System Controller 4 comes as a single enclosure, which consolidates interconnection equipment and reduces installation cost and wiring. There's dedicated space for connecting the IQ Combiner 6C or additional load connections, for a faster and cleaner install. The enclosure is durable NEMA 3R powder-coated steel, built to hold up in demanding environments.
