Enphase IQ Meter Collar

 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 Matters
The 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.
