The Enphase IQ Battery 10 is a second-generation, all‑in‑one AC‑coupled energy storage system delivering 10.08 kWh of usable capacity. It integrates three IQ Battery 3 base units and features twelve embedded IQ8X‑BAT microinverters, each rated at 320 W, for a continuous AC output of 3.84 kW and a peak output of 5.7 kVA 

Key Features

• Lithium iron phosphate (LFP) chemistry: durable, safe, and long-lasting

• Passive cooling: no fans, reducing maintenance and improving reliability

• Grid‑forming capability: automatically switches and provides backup in outages

• Plug‑and‑play installation: AC‑coupled design simplifies retrofit or new solar builds

• Compatibility: Works with IQ6/7/8 Microinverters, IQ System Controller, IQ Combiner, and IQ Gateway

• Monitoring & Control: Full integration via the Enphase App, with firmware and software updates over‑the‑air

• Warranty: 10‑year limited (covers 60 % of capacity at 10 years) 

Technical Specs

• Usable energy: 10.08 kWh

• Continuous output: 3.84 kW

• Peak (surge) output: 5.7 kVA

• Round‑trip efficiency: ~89% AC, 96% DC

• Dimensions: ~664 mm × 1070 mm × 319 mm; Weight: ~341 lbs (155 kg) 

✔ Advantages

• Seamless interoperability with Enphase microinverter systems

• Compact installation footprint with passive cooling

• Safety and longevity from LFP chemistry and strong 10-year warranty

• Reliable grid-forming backup and app-based management

✘ Considerations

• Lower continuous output compared to newer offerings (e.g. IQ 5P or Powerwall 3)

• Higher installed cost per kWh

• Less ideal for non-Enphase solar systems or for homes needing high power output
