The Anker SOLIX F3800 Plus is built for households that want real backup power — not a weekend camping battery rebadged as home backup. 3,840Wh of LiFePO4 capacity pairs with 6,000W continuous dual-voltage output (120V and 240V), meaning clothes dryers, heat pumps, window AC units, and even EV chargers run without converters or workarounds.
When the grid drops, the ~50ms generator bypass switchover keeps sensitive electronics online. When the grid stays up, AC coupling (requires Home Power Panel, sold separately) integrates the unit with existing grid-tied solar — store excess daytime solar, discharge at night, and cut your utility bill during peak-rate windows.
Solar recharge runs up to 3,200W across dual 11–165V MPPT ports, filling the unit in about 1.5 hours of optimal sun. Capacity expands from 3.84kWh to 26.9kWh with six BP3800 batteries, or to 53.8kWh with a paired F3800 Plus and twelve batteries — enough to power most homes for two weeks of outage.
Cells are EV-class LFP. Anker backs the unit with a 5-year manufacturer warranty and their InfiniPower 10-year product lifespan claim. Wheeled chassis with retractable handle — one person moves it.
