Anker SOLIX F3800 Plus: 120/240 V, 3,840 Wh
Anker SOLIX F3800 Plus: 3,840 Wh LiFePO4, 6,000 W across 120/240 V, no published surge rating. What that means for motor loads.

The F3800 Plus is the largest Anker unit in our database: a 3,840 Wh LiFePO4 battery on wheels, 120 V and 240 V output, and room for up to six BP3800 expansion batteries. The original F3800 address now redirects to this page; the older model shares the capacity but lacks the Plus's generator bypass and its solar layout. Check the "Plus" on any listing.
Continuous output — and no peak figure
Anker rates 6,000 W total across 120 V and 240 V, with the NEMA 5-20R household outlets limited to 2,400 W. The page text publishes no surge or peak figure. That matters for motor loads: the 1/2 HP well pump (1,000 W running), the 1/2 HP sump pump (720 W) and the top-freezer refrigerator (360 W) all fit within the continuous rating, but we cannot confirm their starting draw — 7,056 W, 2,150 W and 1,200 W respectively — against a number Anker does not publish.
Using the 0.85 factor explained on the methodology page, 3,840 Wh × 0.85 ÷ 47 W gives about 69.4 hours for the top-freezer refrigerator at its yearly-average draw, or 44.1 hours for the French-door refrigerator at 74 W.
Anker's landing page rates the battery for 3,000+ cycles to 80 %. Thresholds differ between makers, so compare like with like (how makers define cycle life).
Caveats on the maker's pages
The 20 ms UPS switch-over applies only to the three left-hand NEMA 5-20R outlets. Weight is 136.7 lb on the product and landing pages, but a spec card in the page data says 132.3 lb. From a standard 120 V outlet the unit charges at up to 1,800 W; the higher figures need a 240 V generator or Anker's adapter port. Anker listed it as sold out when the record was taken.

Frequently asked questions
Can the F3800 Plus start a well pump?
We cannot confirm it. The 1/2 HP well pump runs at 1,000 W, well inside the 6,000 W rating, but needs 7,056 W to start, and Anker publishes no surge figure for the F3800 Plus. Ask Anker for the surge rating before relying on it for a pump.
Does every outlet work as a UPS?
No. Anker's landing page gives the 20 ms switch-over for the three left-hand NEMA 5-20R outlets only.
How much does it weigh?
136.7 lb per the product and landing pages, including wheels; a spec card elsewhere in the page data says 132.3 lb.
How long would it keep a refrigerator running?
About 69.4 hours for the top-freezer refrigerator at its 47 W yearly average, using the 0.85 factor from our methodology. The running draw fits; the starting draw cannot be checked because Anker publishes no surge figure.
How fast does it charge from a household outlet?
Up to 1,800 W from 120 V AC. Anker does not publish a 120 V charge time; its faster figures need a 240 V generator or the adapter port.
