Enphase IQ Batteries

Enphase IQ Batteries pair with Enphase microinverter solar systems and come in two building blocks: the IQ Battery 5P (5 kWh, 3.84 kW continuous) and the IQ Battery 10C (10 kWh, 7.08 kW continuous). Both carry a 15-year Enphase warranty and use lithium iron phosphate (LFP) chemistry. Installed, an Enphase battery system typically runs $12,000 – $18,000 in Middle Tennessee before incentives, depending on how much storage you add.

Where Enphase fits

• Homes with Enphase solar: the batteries talk directly to Enphase microinverters, which makes them a natural add-on to an existing Enphase array.
• Start small, add later: units stack, so you can begin with essentials backup and add capacity down the road.
• Shade and complex roofs: microinverter systems handle partial shade from Nashville's big hardwoods panel by panel.
• Enphase app: production, storage and backup status in one place.

Good to know

Tennessee has no traditional 1-for-1 net metering, so a battery earns its keep by storing your own solar for evenings and outages. The federal homeowner tax credit ended for systems installed after December 31, 2025. We size storage around the circuits you want backed up, not the biggest number on the spec sheet.
