Models for home backup
IQ Battery 10C
| Usable energy | 10.0 kWh |
|---|---|
| Continuous power | 7.08 kVA at 240 VAC |
| Peak or surge | 56 A for 3 s and 44.8 A for 10 s at 240 VAC (Enphase marketing cites 14.16 kVA peak) |
| Largest system | not stated on the 10C datasheet |
| Whole or partial home | Both. Enphase says the IQ Meter Collar with IQ Combiner 6C enables full home backup, and partial-home backup is also supported |
| Battery chemistry | LFP, with built-in neutral-forming microinverters |
IQ Battery 5P
| Usable energy | 5.0 kWh |
|---|---|
| Continuous power | 3.84 kVA |
| Peak or surge | 7.68 kVA for 3 s; 6.14 kVA for 10 s |
| Largest system | Up to 16 units per system (about 80 kWh) with IQ System Controller 3; 40 kWh per battery port on IQ System Controller 3G |
| Whole or partial home | Both. Whole-home backup if storage is sized to meet NEC 710.15(A), with load control advised. Partial-home through a backup load panel |
| Battery chemistry | LFP |
IQ System Controller 3 / 3G (transfer switch / microgrid interconnect device)
| Function | Connects the home to grid, batteries and PV, switches to backup automatically during an outage, and has a neutral-forming transformer for 120/240 V backup |
|---|---|
| Generator | 3G only: an 80 A (64 A continuous) generator port. Usable generator power tops out around 15.36 kW. The generator must be at least 143% of the battery array rating in battery-only systems |
| Warranty | 10 years |
Warranty
IQ Battery 5P: 15 years or 6,000 discharge cycles from activation, whichever comes first, retaining at least 60% of nameplate capacity. IQ Battery 10C datasheet: up to 15 years or 6,000 cycles at 60% retention, 'restrictions apply'. The product must be sold by Enphase or an authorized reseller and stay at its original location. Register within 45 days (not required in California, Connecticut or states that prohibit it). The system should stay connected to the internet, and claims can be denied if a defect would have been avoided by a firmware update. IQ System Controller 3/3G: 10 years. IQ Combiner, IQ Gateway and Load Controller: 5 years. The US warranty document reviewed is effective for activations on or after Dec 1, 2023.
Altitude
IQ Battery 5P: up to 2,500 m (8,202 ft). IQ Battery 10C: up to 3,000 m (9,842 ft). No derating curve is published. Higher-elevation Colorado mountain towns exceed the 5P rating.
Cold weather
IQ Battery 5P and 10C datasheets: discharging -20 C to 55 C (-4 F to 131 F); charging -20 C to 50 C (-4 F to 122 F); optimum 0 C to 30 C (32 F to 86 F). 10C charging power is reduced below 15 C (59 F). The enclosure is NEMA 3R, rated for rain, sleet, snow and ice. Note: the IQ Battery 5P owner's guide gives a narrower ambient range of -15 C to 55 C (5 F to 131 F).
Monitoring and the app
Enphase App (real-time production, consumption, settings and service messages), through the IQ Gateway over Wi-Fi or Ethernet, with a cellular modem. The owner's guide says live status and energy monitoring 'only work when the system has an active internet connection'. Local monitoring during an outage is not clearly documented. Storm Guard watches National Weather Service alerts and charges the batteries to full before a storm.
Recalls
We found no U.S. Consumer Product Safety Commission recalls of this brand’s home-backup products since 2021, as of October 2026.
What a Colorado homeowner should know
- The system is modular and AC-coupled, built on microinverters: capacity grows in 5 or 10 kWh steps, and it pairs natively with Enphase IQ8 solar. The IQ System Controller 3G adds a generator port for long outages.
- Altitude limits differ by model: the 5P is rated to 8,202 ft and the 10C to 9,842 ft, which matters for mountain installs.
- Domestic-content (DOM) SKUs are US-assembled and are positioned for federal domestic-content tax credit eligibility.
Enphase is sold and installed through certified installers. Tell us what you need and we’ll connect you with one who installs it in your area.
Reviewed October 29, 2026 from manufacturer documents and CPSC records. Specs and terms change; confirm with the manufacturer or your installer. Colorado Peak Power is independent of Enphase.
