Enphase IQ Meter Collar The Enphase IQ Meter Collar is a compact microgrid interconnect device (MID) that enables whole-home backup functionality in Enphase solar battery systems by providing automatic grid disconnection and integrated metering without requiring a backup sub-panel or extensive rewiring. Primary Function & Benefits Acts as the grid disconnect point during outages, allowing an Enphase system with IQ Batteries to safely island the home and supply loads. Eliminates the need to relocate loads to a separate backup panel, significantly reducing installation complexity and labor costs. Includes built-in consumption metering (no external CTs required), simplifying system metering and monitoring. Designed to install between the utility meter and main panel or on a standalone meter socket, with many utilities now approving behind-the-meter installs. Technical & Compatibility Details Rated for 120/240 VAC split-phase, up to 200 A service — suitable for most U.S. residential electrical systems. Weather-resistant NEMA 3R enclosure for indoor/outdoor mounting. Works with Enphase 3rd- and 4th-generation systems, including IQ Battery 5P & IQ Battery 10C, IQ Combiner 5/6C, and IQ Gateway/System Controller as required. Simple commissioning via the Enphase Installer App. Installation & Utility Approval Installation behind the utility meter usually requires local utility approval; installing on a separate meter socket often does not. Utilities like PG&E, SDG&E, and many others have approved the Meter Collar for behind-meter use, helping broaden its applicability. Physical Specs Dimensions: ~6.9″ H × 8.1″ W × 5.0″ D Weight: ~3.6 lb Warranty: ~15 years limited. Why It MattersThe Meter Collar streamlines whole-home backup installations by removing the need for a separate backup panel and extra metering components — lowering cost, reducing installation time, and making robust backup power more accessible to homeowners with Enphase systems.
