The catch
Anker SOLIX F3800
At 132.3 lb, stairs and loading into a vehicle need serious thought.
Side by side
Anker SOLIX F3800 vs F3800 Plus: Charging options improve with Plus, but standalone reserve and output don’t
Quick verdict
A higher-voltage solar array or the supported 240V generator charging setup calls for the F3800 Plus. The original F3800 is right if its lower-voltage solar inputs and existing connections fit your plan. Each starts with 3840Wh and 6000W of native 120V/240V output, so the Plus adds neither standalone battery reserve nor a larger inverter.
Before you buy
Why, and what it costs you
Solar input capacity goes up one third with Plus
Against the original 2400W ceiling, its 3200W combined solar ceiling is 33.3% higher.
Where this comes from
(3200 − 2400) ÷ 2400 × 100 = 33.3%. It measures charging headroom and not a guaranteed rise in daily solar harvest.
The catch
Anker SOLIX F3800 Plus
Weighing 136.7 pounds, it requires wheels and a location chosen in advance for installation. Getting it into a vehicle takes two people.
Anker SOLIX F3800
- Why pick it
- The solar wiring you plan stays safely inside the 60V input limit.
- You prefer the original NEMA 14-50 outlet layout and can do without the Plus charging features.
- The catch
- At 132.3 lb, stairs and loading into a vehicle need serious thought.
Anker SOLIX F3800 Plus
- Why pick it
- The higher 165V input ceiling is something your solar setup needs.
- The documented generator adapter route for 240V charging and bypass is what you’re after.

What this page compares
Anker F3800 and F3800 Plus compared on solar voltage, 240V backup connections and equal battery capacity, including an explanation of charging-mode limits.
The Plus upgrade that counts is in how power gets into the system and not in how much energy the base battery holds.
Which one fits
Pick the situations that sound like you
The panel string I’m planning has 80V open-circuit voltage before cold correction
That is over the original 60V ceiling. For Plus, cold voltage, current and wiring still need checking.

In practice
Differences you will notice
Solar input capacity goes up one third with Plus
Against the original 2400W ceiling, its 3200W combined solar ceiling is 33.3% higher.
How we worked this out
(3200 − 2400) ÷ 2400 × 100 = 33.3%. It measures charging headroom and not a guaranteed rise in daily solar harvest.
Wired in series, two 40V panels go past the original voltage ceiling
Take an illustrative pair rated 40V open-circuit each. Together they total 80V before cold correction, which is over F3800’s 60V limit.
How we worked this out
In series, open-circuit voltages add up: 40 + 40 = 80V. Plus has a 165V ceiling, yet real cold-weather voltage, current and wiring still have to be checked.
At 1kW, each has about three hours of estimated reserve
At a steady 1000W, either base unit yields about 3.07 hours with an 80% usable-energy allowance.
How we worked this out
3840 × 0.8 ÷ 1000 = 3.072 hours. It’s an energy-planning estimate and not a claim about full-home runtime.
Option A
Anker, A1790
SOLIX F3800
A self-contained choice for when a real 240V load means smaller 120V stations won’t do. It’s made to roll into a planned backup setup, and it brings a large inverter and room for more batteries.
- Best for
- Buyers who have confirmed they need 240V and have a safe, planned home or RV connection.
Facts we checked
- 6000W rated combined output from a 3840Wh base battery.
- One station gives native 120V and 240V output.
- 2400W total from two 1200W solar inputs.
- Each solar input has a 60V open circuit maximum.
- Wheels included, at about 132.3 lb.
- One unit can be expanded with batteries up to 26880Wh.
Option B
Anker SOLIX, F3800 Plus
F3800 Plus
This 3,840Wh native-120/240V system comes with dual high-voltage solar inputs, RV outlets and a sizable ecosystem for home expansion.
- Best for
- Whole-home or RV expansion with heavy solar
Facts we checked
- Native 120/240V output, with 3,840Wh LFP capacity
- Up to 3,200W of solar is accepted by two 165V MPPT inputs

| Large outlet layout | NEMA 14-50 and L14-30 | TT-30 and L14-30 | Look at the actual plug instead of assuming the large outlets didn’t change. |
| 240V generator charging route | Original charging arrangement | Up to 6000W through supported adapter and port | A specific generator integration option comes with Plus, subject to equipment and mode restrictions. |
Trade-offs
What each pick costs you
With Anker SOLIX F3800
- Keep every solar input under 60V open circuit, allowing for the voltage rise in cold weather.
With Anker SOLIX F3800 Plus
- Output varies by receptacle, bank and bypass mode, and 240V availability can change when charging from 120V AC. Check the wiring you intend against the current manual, or with an electrician.
Decision guide
How to decide
Your whole charging and outlet plan decides the model, including how it behaves while plugged in.
Solar voltage limits may settle which to buy
Even when a panel’s wattage looks harmless, its open-circuit voltage matters. The original F3800 tops out at a 60V solar ceiling, whereas the Plus allows up to 165V per input, which opens up different series wiring options. Before connecting an array to either model, calculate the cold-weather open-circuit voltage and check current and connector requirements.
A bigger solar number doesn’t come with a bigger battery
The base units each hold 3840Wh. When panels and weather can supply it, the Plus takes a higher solar input, which can help rebuild reserve after an outage. A fully charged unit does not automatically run longer because of it. If your compatible array is small, you may never use the extra charging headroom.
Use the outlet chart that matches how you’ll charge
The Plus has a different outlet layout from the original, and which outputs are available depends on the AC input conditions. According to Anker’s chart, plugging the Plus into a 120V wall outlet leaves its 240V outlet unavailable. The supported generator adapter changes things again. For fixed home wiring, a qualified electrician should check the inlet, the transfer equipment and the intended operating mode.
What this page can’t tell you
- Having native 240V doesn’t mean every outlet stays active in every charging mode.
- Treat the solar voltage example as a screening calculation rather than a complete wiring design.
