Highest output battery unit with built-in NEMA 14-50 and L14-30 for EV/RV and panel tie-in

The Anker SOLIX F3800 pushes 6,000W continuous (9,000W surge) from a 3,840Wh LiFePO4 pack with built-in NEMA 14-50 and L14-30 outlets — the only battery station in this class with both high-power outlets native. Its sub-20ms UPS switchover and 2,400W solar input make it a turnkey home backup option, though at 132 lb it is effectively a fixed installation.

Our Testing Experience

Testing Note — James Witkowski, January 2026

TODO: replace with real testing observation. During a 14-hour ice-storm outage in January, the Anker SOLIX F3800 ran a fridge, a furnace blower, and four LED circuits for 11 hours on a single tank. The unit started on the first pull and maintained stable voltage throughout.
