Powerwall 3 vs Enphase: which battery fits your home?
Powerwall 3 is one integrated unit — 13.5 kWh, 11.5 kW continuous, built-in solar inverter. Enphase is modular — smaller IQ battery units you stack, paired with Enphase microinverters. Pick by your backup loads and your solar setup, not the logo.
