Anker SOLIX F3800
3840 Wh · 6000 W output · LiFePO4 · $3999
✅ Specs verified against the manufacturer's official listing — source · Last checked
Our verdict
This is where portable power stops being portable and starts replacing a standby generator. The 240V split-phase output is the headline feature.
Best for: Whole-home backup where you need 240V loads and can't run a gas generator.
What we like
- 6000W output and 9000W surge handle well pumps, HVAC and dryers
- 120V/240V dual voltage — can hard-wire into a transfer switch
- Expandable to nearly 27kWh
Where it falls short
- 132 lb — this is a wheeled appliance, not something you carry
- $3,999 puts it against real standby generators
