Owner pros and cons
Enphase IQ Battery 10C
- +Built-in microinverters let one unit run backup without a separate inverter
- +Modular: stack up to 80 kWh and add units as budget allows
- +15-year warranty is the longest of the major brands
- +Fan-free, LFP chemistry with no cobalt
- +AC coupling makes it a straightforward retrofit to existing solar
- −7.08 kW continuous trails the Powerwall 3's 11.5 kW, so big loads need several units
- −317 lb installed weight needs a floor pedestal or a strong wall
- −Installed cost with a controller and labor runs roughly $13,000, more than double the hardware price
Enphase IQ Battery 5P
- +15-year / 6,000-cycle warranty - longest in the industry
- +Distributed microinverters mean no single point of failure
- +Modular sizing: start at 5kWh, add modules anytime
- +96% DC round-trip efficiency
- +Seamless integration and monitoring with existing Enphase solar
- +7.68kW peak per module aids motor starting despite modest continuous rating
- −$1,000-1,600 per installed kWh - among the priciest mainstream options
- −Whole-home backup requires 3+ modules plus costly IQ System Controller
- −3.84kW continuous per module is weak alone - central AC needs multiple
- −Enphase-ecosystem lock-in for full functionality
