What the IQ Battery 10C is
The Enphase IQ Battery 10C is an all-in-one AC-coupled home battery with 10.0 kWh of usable capacity and 7.08 kVA of continuous output power. It uses lithium iron phosphate (LFP) chemistry — chosen by Enphase specifically for safety and long cycle life — and includes four embedded grid-forming microinverters, so it can power the home during a grid outage on the circuits you back up.
Safety and reliability
The system is evaluated to UL 9540A, the highest industry standard for battery safety. It cools passively (no moving parts or fans) and updates its software and firmware remotely, so long-term maintenance is minimal for the homeowner.
Warranty
Enphase warrants the IQ Battery 10C to retain at least 60% of its rated capacity for up to 15 years or 6,000 charge/discharge cycles, whichever comes first. The full Enphase limited warranty document defines the specifics and controls in the event of any conflict with a proposal summary.
Frequently asked
How long is the Enphase IQ Battery 10C warranty?
Up to 15 years or 6,000 cycles — whichever comes first — with a guaranteed 60% capacity retention at end of warranty, per Enphase's published limited warranty.
Why does Enphase use LFP chemistry?
Lithium iron phosphate (LFP) is chosen for its safety profile and long cycle life compared to older nickel-based lithium chemistries. It's the same chemistry family used in most modern home battery systems designed for daily cycling.
