Enphase IQ Combiner 6C

The IQ Combiner 6C consolidates interconnection equipment into a single enclosure, simplifying the installation of IQ Series Microinverters and IQ Batteries by offering a consistent, pre-wired solution for residential applications.

IQ Combiner 6C is compatible with the IQ Battery 10C and IQ Meter Collar, serving as an all-in-one solution that includes breaker spaces for PV, battery, and an EV charger. It integrates a load controller with breaker spaces for loads and includes pre-installed and pre-wired current transformers (CTs) for PV and battery metering.

The IQ Combiner 6C, together with IQ Microinverters, the IQ Meter Collar, and the IQ Battery 10C, provides a complete, backup-capable Enphase Energy System.
