The Enphase IQ Battery 10C is the core of Enphase’s fourth-generation home energy system and is a natural battery to evaluate when a homeowner already has Enphase microinverters or wants an AC-coupled, modular storage platform. Infinium designs Enphase backup around the home’s actual loads rather than assuming a standard battery count.
The IQ Battery 10C provides 10 kWh of usable energy and 7.08 kW of continuous power. It uses embedded grid-forming microinverters and integrates with Enphase monitoring and control equipment. For existing Enphase solar owners, keeping solar and storage within the same ecosystem can simplify monitoring and system architecture.
When This Battery Is Often a Strong Fit
Homes with existing Enphase microinverter solar.
Homeowners who prefer a modular AC-coupled battery architecture.
Projects that value Enphase app monitoring and ecosystem integration.
Homes that may expand storage by adding compatible battery capacity later.
Backup designs that benefit from Enphase’s meter-collar / combiner architecture where approved and applicable.

Enphase 10C With Existing Enphase Solar
For many Enphase solar owners, the first battery we evaluate is Enphase because the home already uses microinverter-based solar and Enphase monitoring. That does not mean it is automatically the best choice; we still compare the homeowner’s desired power output, storage capacity, equipment location, expansion plans and budget.
Modular Backup Design
A modular battery design can be useful when a homeowner wants to start with a defined backup goal and expand later. The correct battery count should be based on backed-up loads and outage duration—not simply on home size.
Large Loads and HVAC
Enphase states the 10C is designed to support heavy startup loads in properly configured systems. Infinium still verifies the actual HVAC or pump starting demand and the other circuits that may be active at the same time.
Bay Area Project Proof
Installation and Commissioning
Infinium handles compatibility review, electrical design, permit preparation, installation, commissioning, backup testing and app orientation. If a meter-collar or specific interconnection device is proposed, utility approval and site compatibility must be confirmed for that address.
Frequently Asked Questions
No. It can be considered for new Enphase systems and qualifying existing systems. The existing microinverters, combiner/controller equipment and electrical configuration must be reviewed.
Enphase publishes 10.0 kWh of usable energy per IQ Battery 10C.
Enphase currently publishes a 15-year limited warranty, up to 6,000 discharged cycles, subject to the warranty terms.
Yes, in appropriately sized designs. The number of batteries and any load-management strategy depend on the home’s peak demand and desired outage duration.
The right battery decision is a design decision. Infinium will review your home, existing solar, electrical system and backup priorities before recommending a configuration.
"I worked with Infinium Solar to design and install a residential solar + battery system. The whole team - from sales, to design, to installation, to service & interconnection - is very professional and highly competent. I worked with Gwen, Amy, Kirby, and several others at the Company to get my project completed on time. Their pricing was very competitive (I checked with six local solar installers) and I would absolutely recommend any homeowner to give Infinium a call."
