F3800
- you already own one: same 3,840Wh and 6,000W as the Plus
- your EV charger or 50A RV cord needs a NEMA 14-50
- you want more capacity: a BP3800 battery fits it
F3800 Plus
- you’ll run more than 2,400W of solar, or long high-voltage strings
- you want to recharge from a 240V generator, up to 6,000W
- your RV takes a TT-30 30A plug

Same battery, same inverter. The Plus changed how it charges.
The Anker SOLIX F3800 Plus replaced the Anker SOLIX F3800 at Anker US: the same 3,840Wh and 6,000W at 120/240V, in the same box size. What changed is the charging side: 3,200W of high-voltage solar instead of 2,400W, charging from a 240V generator, and a TT-30 outlet where the NEMA 14-50 used to be. If you already own an F3800, you don’t need to replace it; add a battery instead.
Below: every change with numbers, a 20-second calculator for your own gear, six modeled situations, what it costs to add capacity to an F3800, and what three published tests found.
Same 3,840Wh, same 6,000W at 120/240V, same size. The F3800 Plus changes three things: 3,200W of solar at up to 165V, 240V generator charging, and a TT-30 outlet in place of the NEMA 14-50. The F3800 is no longer sold new by Anker US.
- you need more runtime: add a BP3800 instead
- you use its NEMA 14-50 for an EV or RV
- 2,400W of panels is enough
- you’ll run up to 3,200W of solar
- you’ll recharge from a 240V generator
- your RV uses a TT-30 plug
The five changes that matter
What Anker changed between the F3800 and the F3800 Plus, with the better spec for most buyers flagged. The 3,840Wh battery, the 6,000W inverter at 120/240V, the six 20A outlets, the L14-30 outlet, the 20ms UPS on three outlets, the expansion to 26.9kWh and the size are identical.
Will it run your setup? Check in 20 seconds
Estimates use 85% usable capacity and 70% of rated solar output. Real results vary with temperature, inverter load, shade and appliance cycling. Fridge and freezer watts are daily averages and do not include compressor startup surges.
Runtime by appliance, one at a time
Simple energy estimates, not measured runtimes. Same 3,840Wh in both, about 3,264Wh usable, so one column serves the F3800 and the F3800 Plus.
Same battery, same runtime.
The F3800 and the F3800 Plus both hold about 3,264Wh usable, so every appliance runs just as long on either one.Get our Black Friday alerts for Anker SOLIX

Upgrade, or add a battery?
The lifetime figure divides the Plus price by 3,000 cycles times 3.84kWh; Anker rates the F3800 series at 3,000+ cycles, to 80% on the F3800 Plus spec sheet. Read it as a ranking, not a bill. For an owner, the BP3800 adds runtime without a second station. A second station only makes sense if you want a second 6,000W inverter: Anker says an F3800 and an F3800 Plus work together on the Double Power Hub for 12,000W. Anker US prices move often; the figures here are refreshed daily by our price engine.
The third option: the F3000 at $1,699.99
Anker SOLIX F3000: $1,699.99 today
3,072Wh on wheels, 3,600W through its TT-30R (2,400W on the household outlets), 2,400W of solar, a 20ms UPS and up to three BP3000 batteries for 12,288Wh, at 91.5 lb. Pick it for an RV or a smaller home setup that can grow. Our F3000 review goes deeper. See the F3000 at Anker.
Eight modeled situations, worked out
Same formula as the calculator above. Both carry 3,840Wh, so runtimes are identical; the differences show up when you recharge or plug in something special.
24-hour outage, essentials only
Identical. Either one covers a day and a half; one BP3800 doubles it on both.
Refill from solar, 3,200W of panels
With 2,400W of panels or less they refill at the same pace. The bigger gain on the Plus is the 165V input: longer series strings, thinner cables and less wiring.
A long outage with a 240V generator
The F3800 can only take 1,800W through its 120V AC input, so a big generator idles at a fraction of its output. The Plus takes 3,300W at 240V on its own, 6,000W with an expansion battery, and keeps its L14-30 and TT-30 outlets live while it charges.
Two nights in an RV
Same runtime. A 30A RV cord plugs straight into the Plus’s TT-30. On the F3800, it needs a 14-50 to TT-30 adapter; a 50A RV cord plugs straight into the F3800 and needs an adapter on the Plus.
Charging an EV at 240V
Both deliver up to 6,000W, so a full battery adds roughly half an hour of Level 2 charging. Most mobile EV chargers ship with a 14-50 plug, which fits the F3800 directly; the Plus needs an L14-30 adapter.
Home office through an outage
Identical, including the UPS: 20ms on the three left 120V outlets, with pass-through capped at 1,440W. StorageReview measured 13ms on the F3800.
A full-size fridge, nothing else
Same battery, same runtime. With solar during the day, either can carry a fridge through a multi-day outage.
A 1,500W space heater on high
Heaters drain any portable station fast. Use the low setting and treat the station as a bridge, not a heating plan.

Shorter bar, faster refill. Each row is scaled to its slower unit.
Both: AC charging capped at 1,800W from a 120V wall outletBoth: charging power adjustable in the Anker app
Our times divide capacity by input power, with solar at 70% of panel rating; real charging slows near full.
Every port, side by side
F3800
F3800 Plus
Practical consequence: the F3800’s 14-50 takes most EV mobile chargers and 50A RV cords directly. The Plus’s TT-30 takes 30A RV cords directly. How-To Geek’s existing 50A cable no longer fit the Plus and needed an L14-30P adapter cable.
09 · NoiseNoise: F3800 vs F3800 Plus
No clean comparison. Notebookcheck measured the Anker SOLIX F3800 at about 42dB at 1 m during a long 3,000W draw; AppleInsider found the Anker SOLIX F3800 Plus whisper-quiet until heavily loaded, then up to 60dB, distance not stated.
Anker publishes no rating for either. Both share the same battery, inverter and enclosure size.Every figure we found, with its source
What reviewers heard: Silent at low load; drawing 3,000W for a long time, noise was only about 42dB at 1 m (Notebookcheck, EU unit).
What reviewers heard: Whisper-quiet until heavily loaded; then the fans may reach 60 decibels (AppleInsider).
Measured by a tester Brand figure
- Lower the AC charging power in the Anker app when the unit sits in a living space overnight.
Cold and heat: F3800 vs F3800 Plus
The Anker SOLIX F3800 and the Anker SOLIX F3800 Plus share the same limits: charging from 32°F to 104°F, running from −4°F to 104°F. Anker publishes no storage range and no water rating for either.
Figures from the F3800 (A1790) and F3800 Plus (A1790P) user guides.- In a garage in winter, charge either one indoors or wait for the battery to warm up: neither charges below 32°F.
App, UPS and smart features
Nearly the same. The Anker SOLIX F3800 Plus adds Storm Guard with the Home Power Panel; Anker lists time-of-day and peak shaving modes on the Anker SOLIX F3800. Both switch in 20ms.
Anker says the two can work together on the Double Power Hub, the Home Power Panel and the Transfer Switch.Green zone: a switch under about 16ms, which most desktop PCs ride through without restarting.
Does it prepare for storms? With the Home Power Panel, the Anker SOLIX F3800 Plus starts charging when it is notified of extreme weather; Anker lists no storm mode for the Anker SOLIX F3800.
Can it charge off-peak? Anker lists time-of-day and peak shaving modes for the Anker SOLIX F3800; its F3800 Plus page lists no such mode.
Does it work as a UPS? On both, the three left 120V outlets switch in 20ms, with pass-through capped at 1,440W. StorageReview measured 13ms on the Anker SOLIX F3800.
Does it connect to a home panel? Both work with Anker’s Double Power Hub, Home Power Panel and Transfer Switch, and Anker supports pairing an Anker SOLIX F3800 with an Anker SOLIX F3800 Plus.
Can it charge an EV? Both charge an EV from the 240V outlets; Anker asks you to set the EV charging rate below 25A.
How does the app connect? Both use the Anker app over Wi-Fi or Bluetooth, with adjustable charging power and auto-off timers.
Warranty and support
Same term: Anker lists 5 years for the Anker SOLIX F3800 (archived US page) and for the Anker SOLIX F3800 Plus. Anker’s registration page says registering activates the Plus’s 5 years.
The F3800 is discontinued, so check the warranty date on a leftover or used unit.Subject to each brand’s warranty terms and eligibility.
Anker rates the F3800 series at 3,000+ cycles, about 8 years at one full cycle a day; the F3800 Plus spec sheet puts the end point at 80% capacity. Calendar aging and heat also reduce capacity, so read the rating as a ceiling.
- If you buy a leftover or used F3800, check the warranty date first: Anker US no longer sells it.
- Keep proof of purchase and register the F3800 Plus with Anker when it arrives.
What reviewers report
We have not lab-tested these two units. Here is what 8 published reviews found, with the source, author and date for each point. Reviews of UK and EU units are flagged: those models charge from 230V outlets and have different sockets, so their charge times and outlet findings don’t carry over to US units.

Practical limits before you buy
- The F3800 is discontinued. Anker US redirects its page to the F3800 Plus. Leftover or used units exist; check the warranty date before buying one.
- The Plus has no NEMA 14-50. A 50A RV cord or an EV mobile charger with a 14-50 plug needs an adapter to the L14-30.
- 240V generator charging needs Anker’s Generator Input Adapter. It is sold separately, works with a single Plus only, and turns off the six 5-20R outlets while connected.
- 6,000W generator charging needs an expansion battery. A Plus on its own takes 3,300W from a 240V generator.
- No surge figure for the Plus. The 9,000W often quoted belongs to the original F3800; Anker publishes none for the Plus. Check the starting watts of big motors.
- Keep the F3800 under 60V of solar. Its XT-60 inputs stop at 60V; higher-voltage strings damage it. The Plus takes up to 165V.
- UPS covers three outlets and 1,440W on both. The L14-30 isn’t available while either charges from a 120V outlet.
- Both weigh over 130 lb. Wheels and a handle help on flat floors; plan on two people for stairs or a truck bed.
- F3800, per its US documentation: While recharging on AC, only the 120V UPS outlets can power other devices.
- F3800, per its US documentation: Each solar input max open-circuit voltage is 60V, including panels in series.
- F3800 Plus, per its US documentation: The 240V output cannot be used while the unit charges from 120V AC.
- F3800 Plus, per its US documentation: On a 120V wall outlet only the TT-30R (no UPS) and the 3 leftmost NEMA 5-20R (UPS) work, with a 1,440W bypass limit.
Frequently asked questions
Is the Anker SOLIX F3800 discontinued?
Yes, at Anker US: its product page redirects to the F3800 Plus, which keeps the same battery and inverter and changes the charging side.
Should I upgrade my F3800 to the F3800 Plus?
Only if you need more than 2,400W of solar, high-voltage solar strings, 240V generator charging or a TT-30 outlet. For more runtime, add a BP3800 battery instead; it fits both.
Do BP3800 expansion batteries work with both?
Yes. Both take up to six BP3800 batteries of 3,840Wh each, for 26.9kWh per unit.
Can I use an F3800 and an F3800 Plus together?
Yes, per Anker’s FAQ: they can share a Double Power Hub, a Home Power Panel and a Transfer Switch.
Does the F3800 Plus have a NEMA 14-50 outlet?
No. It has a TT-30 (120V, 3,000W) and an L14-30 (240V, 6,000W). The original F3800 had a 14-50 and an L14-30.
How long will either run a refrigerator?
Using a 60W average draw and 85% usable capacity, about 54 hours on either, since both carry 3,840Wh. Each BP3800 adds about the same again.
Can the F3800 Plus charge from a 240V generator?
Yes, with Anker’s Generator Input Adapter: up to 3,300W on its own and up to 6,000W with an expansion battery. The F3800 can only charge from a generator through its 120V AC input, at 1,800W.
Are they the same size?
Yes: 27.6 × 15.3 × 15.6 inches, wheels included. The Plus weighs 135.6 lb in its user guide, against 132.2 lb for the F3800.
Do reviews confirm the rated capacity?
F3800: Took 4,930Wh to charge from 0 to 100% and delivered 2,980Wh before the inverter cut off (StorageReview). F3800 Plus: With an expansion battery it ran a full-size fridge about 63 hours, delivering roughly 4,248Wh of AC (PCMag). Inverter losses usually take 10 to 20% on AC, which is why our calculator uses 85% of the rating.
How loud are the F3800 and the F3800 Plus?
F3800: no official rating; Notebookcheck measured about 42dB at 1 m (EU unit). F3800 Plus: no official rating; one reviewer measured up to 60dB, distance not stated. Fans run hardest during fast charging and near full output.
What does the warranty require?
F3800: 5 years. F3800 Plus: 5 years once registered with Anker. Keep proof of purchase and register the unit with Anker when it arrives.
