Enphase Energy, Inc. announced an expanded number of utilities have approved the Enphase IQ Meter Collar for behind-the-meter installation. Pacific Gas and Electric Company (PG&E) and San Diego Gas & Electric have approved the device for use in their service territories, along with 46 additional utilities across the United States. Many additional utility approvals are expected in the near future.
The IQ Meter Collar is a compact microgrid interconnection device that mounts behind the utility meter or on a standalone meter socket. It enables whole-home backup without moving circuits to a dedicated backup sub-panel, eliminates the need for additional consumption current transformers, and supports safe grid isolation. The streamlined design helps reduce wall space, wiring complexity, and installation time.
It has saved my crew countless hours on the job site and delivers an incredibly efficient homeowner experience. The IQ Meter Collar are part of the 4th-generation Enphase Energy System, designed to make home backup faster and easier with three core components: the IQ Battery 10C, the IQ Meter Collar, and the IQ [11] Combiner 6C. Together, this system offers a smaller footprint, a simplified bill of materials, integrated metering, and a streamlined commissioning process that can help unlock more single-day deployments.
The IQ Battery 10C provides 10 kWh of usable energy with 7.08 kW of continuous power, uses LFP chemistry, and includes neutral forming microinverters to enable backup functionality. The IQ Combiner 6C consolidates interconnection equipment in one enclosure with integrated breaker spaces and pre-installed metering. The 4th-generation system is backed by a 15-year limited warranty.
