IQ Combiner 6C with three pre-installed breakersThe 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 enclosure incorporates three integrated breakers, with two serving photovoltaic (PV) systems and one dedicated to the battery.
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.
