Enphase Energy, Inc., a global energy technology company and the world’s leading supplier of microinverter-based solar and battery systems, has announced that more than 2,500 SunPower customers have transitioned to Enphase monitoring since SunPower’s bankruptcy filing in August 2024.

Several hundred thousand SunPower customers currently use its proprietary PV Supervisor communications gateway for monitoring. Many of these systems are built with Enphase microinverters. Enphase is offering various options for these homeowners, ranging from system monitoring, service plans, and even full system upgrades.

Nitish Mathur, Senior Vice President of Customer Experience at Enphase Energy, acknowledged the uncertainty faced by SunPower system owners. He affirmed Enphase’s commitment to honoring warranties for its microinverters used in SunPower systems and ensuring a smooth transition to Enphase monitoring. Mathur noted that thousands have already switched, with efforts underway to support many more in managing their systems confidently.

The Enphase^® Monitoring Kit enables homeowners to track energy production and consumption in real time through the Enphase mobile app. The kit includes an IQ^® Gateway device along with current transformers and can be commissioned by Enphase’s field service team in coordination with our installer partners. The hardware is covered by a five-year limited warranty. While the kit works seamlessly with most solar inverters, compatibility with certain third-party batteries such as SunPower SunVault is not yet available.

Enphase is also offering SunPower customers its annual service plan solution, Enphase Care, as well as access to its Third-Party Upgrade Program to replace older string inverters and legacy SolarBridge microinverters with IQ Microinverter-based systems.
