Head-to-head
Anker SOLIX F3800 vs F3800 Plus: Plus improves charging options, not standalone reserve or output
The short answer
Choose F3800 Plus for a higher-voltage solar array or the supported 240V generator charging setup. Choose the original F3800 if its lower-voltage solar inputs and existing connections fit your plan. Both start with 3840Wh and 6000W of native 120V/240V output, so Plus does not add standalone battery reserve or a larger inverter.
Before you choose
The reasoning and the trade-offs
Plus adds one third more solar input capacity
Its 3200W combined solar ceiling is 33.3% higher than the original 2400W ceiling.
What this is based on
(3200 − 2400) ÷ 2400 × 100 = 33.3%. This is charging headroom, not a guaranteed increase in daily solar harvest.
Main trade-off
Anker SOLIX F3800 Plus
At 136.7 pounds it needs wheels and a planned installation location. Lifting it into a vehicle is a two-person job.
Anker SOLIX F3800
- Choose it for
- Your planned solar wiring stays safely within the 60V input limit.
- You want the original NEMA 14-50 outlet layout and do not need the Plus charging features.
- Main trade-off
- 132.3 lb makes stairs and vehicle loading a serious consideration.
Anker SOLIX F3800 Plus
- Choose it for
- Your solar setup needs the higher 165V input ceiling.
- You want the documented generator adapter route for 240V charging and bypass.

About this comparison
Compare Anker F3800 and F3800 Plus by solar voltage, 240V backup connections and equal battery capacity, with charging-mode limits explained.
The important Plus upgrade is how power gets into the system, not how much energy the base battery holds.
Winner by situation
Start with what you need it to do
My planned panel string has 80V open-circuit voltage before cold correction
It exceeds the original 60V ceiling. Plus still requires checking cold voltage, current and wiring.

What matters in practice
The differences that matter
Plus adds one third more solar input capacity
Its 3200W combined solar ceiling is 33.3% higher than the original 2400W ceiling.
How we reached this conclusion
(3200 − 2400) ÷ 2400 × 100 = 33.3%. This is charging headroom, not a guaranteed increase in daily solar harvest.
Two 40V panels in series exceed the original voltage ceiling
An illustrative pair rated at 40V open-circuit each totals 80V before cold correction, above F3800’s 60V limit.
How we reached this conclusion
Series open-circuit voltages add. 40 + 40 = 80V. Plus has a 165V ceiling, but actual cold-weather voltage, current and wiring must still be checked.
Both have about three hours of estimated reserve at 1kW
An 80% usable-energy allowance gives about 3.07 hours from either base unit at a steady 1000W.
How we reached this conclusion
3840 × 0.8 ÷ 1000 = 3.072 hours. This is an energy-planning estimate, not a full-home runtime claim.
Choice A
Anker, A1790
SOLIX F3800
A self-contained option when a real 240V load rules out smaller 120V stations. It is designed to roll into a planned backup setup, with a large inverter and space to add batteries.
- Best matched use
- Buyers with verified 240V needs and a safe, planned home or RV connection.
Checked facts
- 3840Wh base battery and 6000W rated combined output.
- Native 120V and 240V output from one station.
- Two 1200W solar inputs for 2400W total.
- Maximum 60V open circuit per solar input.
- About 132.3 lb including wheels.
- Supports battery expansion to 26880Wh on one unit.
Choice B
Anker SOLIX, F3800 Plus
F3800 Plus
A 3,840Wh native-120/240V system with dual high-voltage solar inputs, RV outlets and a large home-expansion ecosystem.

Meaningful differences
What changes the fit
| What changes | Anker SOLIX F3800 | Anker SOLIX F3800 Plus | Why it matters |
|---|---|---|---|
| Base battery capacity | 3840Wh | 3840Wh | Plus gives no extra nominal reserve before expansion. |
| Rated AC output | 6000W, native 120V/240V | 6000W, native 120V/240V | Both can supply split-phase loads within their outlet and total limits. |
| Total solar input | 2400W | 3200W | Plus adds 800W of combined solar input capacity. |
| Solar input voltage ceiling | 60V per input | 165V per input | Some series-wired panel groups fit Plus but exceed the original voltage limit. |
| Solar input layout | Two inputs, up to 1200W each | Two inputs, up to 1600W each | Each input must be sized separately. |
| Large outlet layout | NEMA 14-50 and L14-30 | TT-30 and L14-30 | Check the actual plug rather than assuming the large outlets stayed unchanged. |
| 240V generator charging route | Original charging arrangement | Up to 6000W through supported adapter and port | Plus adds a specific generator integration option, with equipment and mode restrictions. |
What you give up
Every choice has a cost
If you choose Anker SOLIX F3800
- Each solar input must stay below 60V open circuit, including the rise in cold weather.
If you choose Anker SOLIX F3800 Plus
- Output depends on the receptacle, bank and bypass mode, and 240V availability can change while charging from 120V AC. Reconcile the intended wiring with the current manual or an electrician.
What matters in practice
How to make the call
Choose the model that fits the complete charging and outlet plan, including what happens while it is plugged in.
The solar voltage limit can decide the purchase
A panel’s open-circuit voltage matters even when its wattage looks harmless. The original F3800 has a 60V solar ceiling, while Plus allows up to 165V per input. That opens different series wiring options. Calculate cold-weather open-circuit voltage and check current and connector requirements before connecting an array to either model.
The bigger solar headline does not mean a bigger battery
Both base units hold 3840Wh. Plus accepts a higher solar input when the panels and weather can provide it, which can help restore reserve after an outage. It does not automatically extend the runtime of a fully charged unit. Buyers with a small compatible array may never use the extra charging headroom.
Read the outlet chart for the charging mode you will use
The Plus outlet layout differs from the original, and available outputs change with AC input conditions. Anker’s chart shows that plugging Plus into a 120V wall outlet does not leave its 240V outlet available. The supported generator adapter changes the arrangement again. For fixed home wiring, have a qualified electrician check the inlet, transfer equipment and intended operating mode.
What this comparison cannot tell you
- Native 240V capability does not mean every outlet remains active in every charging mode.
- The solar voltage example is a screening calculation, not a complete wiring design.
