Add the IQ Battery 10C to existing third-party solar

The IQ Battery 10C now works with existing third-party solar systems, providing whole-home backup, multi-day outage resilience, and unified energy monitoring. No replacement of existing solar equipment required.

Add IQ Battery 10C to existing third-party solar

Add whole-home backup capability to homes with an existing solar system by retrofitting an IQ Battery 10C*, leaving the existing inverter and panels in place.

Add Enphase solar and IQ Battery 10C
to expand capacity

Add Enphase solar and the IQ Battery 10C* alongside an existing string-inverter system. Increase total generation capacity and add backup for homes with growing energy needs.

*California customers can add the IQ Battery 10C and preserve NEM 1.0 or 2.0 status. Visit the NEM expansion page for all the details.

Available configurations

IQ Combiner 6C

Built-in connection point for third-party solar, supports up to 15.36 kVA of third-party PV.


Charging

Existing solar can charge the IQ Battery 10C on-grid and off-grid, subject to utility rules.


Backup behavior

Third-party solar stays online during outage; battery recovers charge from it each morning; supports multi-day outages.


Monitoring

Unified* production, consumption and storage view in the Enphase App, including third-party solar output.


Power control

Busbar overload control is supported when integrating with third-party solar systems. If expanding with additional Enphase solar, NEM expansion* with non-export is supported.

*Unified monitoring is available only in whole-home backup configurations. Not available for partial-home or grid-tied-only setups.

*California customers with existing NEM 1/2 tariffs can use zero export/NEM expansion to avoid transitioning to NBT/NEM 3.0. Aggregate Power Export Limiting (PEL) is not currently supported. Learn more.
