FAQ
How long will the Anker SOLIX F3800 run a refrigerator?
Around 22 hours for a full-size refrigerator averaging 150W, assuming ~85% inverter efficiency. Actual runtime depends on the fridge's compressor duty cycle and ambient temperature.
Does the Anker SOLIX F3800 use a LiFePO4 battery?
Yes. It uses LiFePO4 (LFP) cells rated for about 3,000 cycles to 80% capacity — roughly 8+ years of daily cycling.
What solar panels work with the Anker SOLIX F3800?
Any panel (or array) within its 11-160V MPPT voltage window and up to 2400W, connected via XT60/MC4-adapter. Staying inside the voltage window matters more than matching wattage.
How fast does the Anker SOLIX F3800 recharge from a wall outlet?
About 80 minutes from 0 to 80% on AC power.
