Enphase Energy Brings IQ Battery 10C and Whole-Home Backup to Existing Third-Party Solar Systems
Millions of homes already have solar but do not have battery backup. With the IQ Battery 10C, IQ® Combiner 6C, and IQ® Meter Collar, homeowners can keep their existing solar investment while adding Enphase storage, whole-home backup, energy management, and monitoring through the Enphase® App. The IQ Battery 10C delivers 10 kWh of usable energy and 7.08 kW of continuous power, while the IQ Combiner 6C can integrate up to 15.4 kVA of existing third-party solar.
The IQ Meter Collar makes the backup architecture particularly simple. Installed behind the utility meter, it combines microgrid interconnection functionality and energy consumption metering in a compact device. It enables whole-home backup without requiring a dedicated backup subpanel or extensive load rewiring, reducing equipment and installation complexity. The IQ Meter Collar is now qualified across 71 utilities in

During an outage, the existing third-party solar system can continue producing energy and charging the IQ Battery 10C. If the battery is depleted overnight, solar production can recharge it when the sun returns, helping keep the home powered through extended outages. Homeowners can see solar production, home energy consumption, and battery storage together in the Enphase App, including energy generated by the existing third-party solar system.
"Homeowners want backup and more control over their energy, and many of them already have solar," said
Adding a battery to an existing solar system can also help homeowners qualify for grid-services programs that provide additional savings. In participating programs such as
"Most homes with solar still don't have battery backup, and many were built with other manufacturers' equipment," said
Support for third-party solar systems with the IQ Battery 10C is available now through Enphase installation partners across
