| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 3,840 Wh |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | LFP (lithium iron phosphate) |
| Cycle lifeHow many full charge and discharge cycles the cells are rated for before they hold less than the stated share of their original capacity. | 3,000+ cycles. Anker's page also describes a 10-year lifespan. |
| ExpansionExtra battery units that add storage to the same system. | Up to 6 BP3800 expansion batteries (3,840 Wh each) per unit. Anker's headline is up to 53.8 kWh at 12 kW; the page does not spell out how many F3800 Plus units that takes. |
| Output | |
| AC output (continuous)The power it can deliver all the time. Add up the watts of what you want to run at once and stay below this. | 6,000 W maximum in total |
| AC outputThe power it can deliver through its sockets or inverter, in watts. | Six 120 V NEMA 5-20R outlets (Anker's spec line gives 20 A and 2,400 W max, without saying whether that is per outlet; the three on the left are the UPS outlets), one 120 V TT-30R (3,000 W max) and one 120/240 V L14-30R (6,000 W max). The 240 V output cannot be used while the unit charges from a 120 V outlet. |
| USB-APorts for phones, tablets and small devices. | 5 V 2.4 A (12 W max) per port; the page does not give the number of ports |
| USB-CPorts for laptops, phones and tablets. Power delivery up to 100 W can charge most laptops. | Up to 100 W per port; the page does not give the number of ports |
| Car outletA 12 V socket like the one in a car, for car accessories. | 12 V 10 A |
| Backup outputA separate socket that keeps selected devices running when the grid is down. | Home Power Panel port: 6,000 W max (input and output), 120/240 V |
| Charging | |
| AC chargingHow fast it charges from a wall socket. Higher means a shorter wait. | 1,800 W maximum from a 120 V 15 A outlet. In bypass mode from a 120 V outlet the AC input is up to 1,440 W. The Home Power Panel and generator port takes up to 6,000 W at 240 V. |
| Solar inputHow much solar panel power it accepts. A higher figure fills the battery faster on a sunny day. | 3,200 W in total through two inputs, each 11 to 165 V at up to 17 A (1,600 W each). Voltage above 165 V can damage the inputs. |
| Solar charging timeHow long a full charge takes from solar panels, in the conditions the maker names. | 100% in 1.5 hours; the page also says a full recharge takes under 2 hours in optimal sunlight |
| Pass-through chargingWhether it can power devices while it is itself being charged. | Yes: generator bypass of up to 6,000 W at 240 V (with the Anker SOLIX generator adapter, single unit only) and up to 3,000 W at 120 V; 1,440 W from a 120 V wall outlet |
| Backup switchover (EPS)What happens when the grid fails. EPS means it takes over automatically. | 20 ms on the UPS outlets when a 120 V wall outlet is connected; 30 ms to a generator and 50 ms back |
| Solar and off-grid | |
| Works with solar panelsWhether you can charge it from solar panels. Yes means a built-in solar input or a compatible solar setup; read the detail for the voltage and power limits. | Yes: up to 3,200 W through two 11 to 165 V solar inputs. |
| Off-grid useWhether the maker describes it running with no grid connection at all, for example in a cabin, van or off-grid home. Backup only means it covers power cuts but needs the grid the rest of the time. | Yes: Anker markets it for off-grid use and RVs, and it can run from solar and a 120/240 V generator without the grid. |
| Housing and warranty | |
| Dimensions (L × W × H)Check the space before you buy, including room around it for airflow and cables. | 27.6 × 15.3 × 15.6 in including wheels, as Anker labels them (about 70.1 × 38.9 × 39.6 cm, converted by us). The unit stands upright, so we do not map the numbers to axes. |
| WeightMatters for lifting, wall mounting and moving it. | 136.7 lb (about 62 kg, converted by us); a BP3800 expansion battery weighs 72.8 lb |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | Not published by Anker |
| Protection ratingIP ratings show protection from dust and water. IP55 and IP65 are rated for outdoor-style exposure; check the installation guidance. | Not published by Anker |
| Noise levelFan noise while working. | Not published by Anker |
| ConnectivityHow you monitor and control it, usually through an app. | Anker app to track and manage charging, usage and battery status in real time |
| WarrantyThe period the maker covers. Read the terms: conditions and capacity guarantees differ. | 5 years |
How long will it run your devices?

The estimate assumes 85% of the rated capacity is usable after conversion losses. Anker SOLIX does not state this figure, so we use a cautious assumption. Real running times vary with temperature, battery age and how each device draws power.
Compatible with
What Anker SOLIX says this product works with. Anything not listed here is not confirmed.
- Extra batteries
- Up to six BP3800 expansion batteries (3,840 Wh each) per unit. Anker's page lists the BP3800 as the battery for the F3800 and F3800 Plus.
- Anker SOLIX Home Power Panel, transfer switch and inlet box
- Anker says it works with the Home Power Panel, a transfer switch and an inlet box, and with the Double Power Hub. The Home Power Panel delivers 6,000 W when used with an expansion battery.

- Not compatible: Not compatible: Anker says to connect solar panels (11 to 165 V) directly to the F3800 Plus instead.
Rules where you live
A portable power station is not wired into your home, so it is simple to use almost anywhere. The F3800 Plus is built for North American 120 V/240 V, 60 Hz power, and connecting any power station to your home circuits is a different matter with different rules by country. See our country guides for the rules, incentives and prices where you live.

Common questions about Anker SOLIX F3800 Plus
What is the difference between the F3800 and the F3800 Plus?
Anker's comparison table says the Plus adds a 240 V generator bypass, takes up to 3,200 W of solar (against 2,400 W) and accepts up to 6,000 W of AC input (against 1,800 W). Both are 3,840 Wh and 6,000 W.
Can the F3800 Plus run a generator and the house at the same time?
Anker says a 240 V pure sine generator can feed the Home Power Panel port for up to 6,000 W of bypass to the L14-30R outlet, and a 120 V generator up to 3,000 W to the TT-30R outlet. Follow Anker's guide for which outlets work in each case.
Can the F3800 Plus charge an electric car?
Anker says double-pressing the AC outlet button turns on EV mode, and the charging rate must be set below 25 A so the unit can charge a car such as a Tesla.
