Fremont, CA — November 17, 2025 — Enphase Energy, Inc. (NASDAQ: ENPH), a leader in energy technology, has announced an important expansion in utility approvals for its innovative IQ® Meter Collar. This development is set to enhance the capabilities of behind-the-meter solar and battery systems across the United States, particularly impacting service areas like California.

1. Expanded Utility Approvals

The Enphase IQ Meter Collar has received approval from notable utilities, including Pacific Gas and Electric Company (PG&E) and San Diego Gas & Electric, along with an impressive 46 additional utilities nationwide. The company anticipates further approvals in the near future, which are expected to enhance the installation and adoption of home backup energy systems.

The IQ Meter Collar serves as a compact microgrid interconnection device that can be mounted behind existing utility meters or on standalone meter sockets. This innovative design enables homeowners to achieve whole-home backup power without the need for complex rewiring or additional equipment.

2. Streamlining Installation Processes

Enphase's IQ Meter Collar is engineered to simplify the installation process significantly. By eliminating the need for dedicated backup sub-panels and additional current transformers, the device reduces wall space requirements and installation time. The straightforward design allows installers to deliver whole-home backup faster and more efficiently, a feature that has received high praise from industry experts.

Industry Perspectives

Stan Pipkin, CEO of Lighthouse Solar, emphasized the device's efficiency: “The IQ Meter Collar and the 4th-generation Enphase Energy System make whole-home backup faster and simpler to deliver.” He highlighted how the integrated metering and streamlined workflow result in better value and more predictable commissioning for installers.

Chad Wahlquist, founder and CEO of NewLeaf Solar, echoed these sentiments: “The IQ Meter Collar is one of the most elegant pieces of equipment our industry has seen in a decade.” He noted that it has saved installation crews countless hours on the job site, ultimately enhancing the homeowner experience.

Seth Tilley, sales director at San Diego County Solar, remarked on the impact in California’s market, stating, “The IQ Meter Collar really has been a game-changer. It allows us to provide whole-home backup power for thousands of dollars less than was possible previously.”

3. The 4th-Generation Enphase Energy System

The IQ Meter Collar is a critical component of the 4th-generation Enphase Energy System, which includes the IQ®Battery 10C and the IQ®Combiner 6C. This system is designed to facilitate home backup solutions that are not only efficient but also user-friendly.

The IQ Battery 10C provides 10 kWh of usable energy and 7.08 kW of continuous power, utilizing Lithium Iron Phosphate (LFP) chemistry for safety and longevity. Coupled with the IQ Combiner 6C, which consolidates interconnection equipment, the system presents a smaller footprint and a simplified bill of materials.

Ken Fong, senior vice president of sales at Enphase Energy, stated, “With expanded utility approvals for the IQ Meter Collar, installers can deliver whole-home backup more simply and at greater scale.” He described this development as a meaningful step towards reducing installation complexities and improving reliability.

4. Conclusion

Enphase Energy's expanded utility approvals for the IQ Meter Collar mark a significant milestone in the transition towards more efficient and accessible home energy solutions.
