Anker SOLIX F3800 Plus Review
6,000 W of 120/240V power and 3,200 W of solar input for under $3,000. The most output per dollar among the 240V stations we track.
The F3800 Plus is the best-priced way to get serious 240V output. Its 6,000 W runs a well pump alongside a fridge, freezer and lights, and its 3,200 W of solar input beats every station we track except the Jackery 5000 Plus and DELTA Pro Ultra. Its 3.8 kWh battery is smaller than its rivals, so for long outages plan on an expansion battery or solar panels.
Who it's for
Buy the F3800 Plus if you have a 240V well pump or want to back up several circuits through a transfer switch, and you would rather spend on output than on raw capacity. It suits homes with solar panels or where outages last a day or less.
Skip it if you mainly need to keep a fridge and internet running. A 2 kWh station such as the Bluetti Elite 200 V2 does that for a third of the price.

What it can run
You get about 3,260 usable watt-hours after inverter losses.
hours ≈ 3,840 × 0.85 ÷ watts used
- Refrigerator, router and LED lights (about 220 W average): roughly 15 hours.
- Well pump cycling on and off (about 400 W average): roughly 8.2 hours on its own. See running a well pump.
- Fridge, freezer, lights and a furnace fan (about 780 W average): roughly 4.2 hours.
The 6,000 W output means you rarely hit the power limit; the battery runs out first. That is why the Black Friday bundle with an expansion battery (7.7 kWh for $4,299, seen late October 2026) is worth a look.
Pros and cons
What we like
- 6,000 W of 240V output at a mid-range price
- 9,000 W surge for pump and compressor starts
- 3,200 W solar input
- Expands to 26.9 kWh
- Anker's 5-year warranty
What to know
- Smallest battery of the 240V group
- Less expansion room than EcoFlow or Jackery
- No fast-charge headline like the DELTA Pro 3
- Weight is not clearly published
How it compares
| Model | Capacity | Output | 240V | List price | Per kWh |
|---|---|---|---|---|---|
| Anker SOLIX F3800 Plus | 3,840 Wh | 6,000 W | Yes | $2,799 | $729 |
| EcoFlow DELTA Pro 3 | 4,096 Wh | 4,000 W | Yes | $3,699 | $903 |
| Jackery Explorer 5000 Plus | 5,040 Wh | 7,200 W | Yes | $3,149 | $625 |
| Bluetti Apex 300 | 2,765 Wh | 3,840 W | Yes | $2,399 | $868 |
The F3800 Plus delivers 2,000 W more than the DELTA Pro 3 for $900 less at list. The Jackery 5000 Plus adds 1.2 kWh and 1,200 W for about $350 more. See our head-to-head with the DELTA Pro 3.
Bottom line
If output matters more than capacity, the F3800 Plus is the 240V station to get. Pair it with solar or an expansion battery for outages longer than a day.
