Anker SOLIX F3800 vs F3800 Plus: Models, Batteries, and Home Backup Kits

For a new Anker SOLIX F3800 system, choose the F3800 Plus if you need its higher solar input or generator bypass; both US generations still start at 3,840Wh and 6,000W of 120V/240V output. Keep an original F3800 if its charging limits and outlets already suit you; choose a BP3800 expansion battery when storage is the shortfall, since it works with either generation. Choose the house connection separately: Smart Home Power Kit and Home Backup Kit describe different equipment, not a larger battery.

F3800 vs F3800 Plus: the US models compared

These are manufacturer ratings for a single station unless a row explicitly says otherwise.

• 2,400WOriginal F3800 maximum solar input
• 3,200WF3800 Plus maximum solar input

Default choice for a new system: Anker SOLIX F3800 Plus

The Plus earns our default recommendation for the extra recharge options, rather than extra running watts. Its base package lists the station, AC charging cable, two solar charging cables and manual; it does not list solar panels, an expansion battery or a Home Power Panel. Anker's standalone Plus page shows Sold Out; verify the exact bundle's availability before scheduling installation.

Check price on Amazon.

The Plus's TT-30R is rated 120V, 25A and 3,000W, while its L14-30R is 120V/240V, 25A and 6,000W, within the 6,000W shared total. Use the stated current limit, rather than the connector name, to choose an RV or EV load. The key limitation: plugging the Plus into a 120V wall outlet disables its 240V L14-30R and the right-hand bank of ordinary outlets.

Anker lists the three left-hand UPS outlets and TT-30R as available in that condition, with a 1,440W bypass limit; only the UPS outlets get the stated 20 ms switchover.

Original F3800: keep it when its connections fit

The original retains the same base storage and continuous output, and its high-power sockets include NEMA 14-50 where the Plus has TT-30R. If your equipment already fits that station, adding compatible storage may solve more than replacing it. Anker's former US F3800 product URL now displays Plus content; identify the original using its name and ports in the model-labelled comparison.

Anker's Home Power Panel page also says the original's 240V ports do not function in UPS mode.

Add runtime: Anker SOLIX BP3800 expansion battery

The BP3800 is a 3,840Wh LFP battery compatible with F3800 and F3800 Plus, and its box includes the battery-to-host cable. It cannot charge or discharge independently, and it does not add another AC inverter. The BP3800's published weight is 72.8 lb, so plan where the expanded system will live before ordering.

Anker permits mixed F3800 and Plus stations through either Home Power Panel or Double Power Hub; that is different from directly connecting stations as expansion batteries.

Connect the house: Home Power Panel and the US kit

The US Smart Home Power Kit is titled Smart Home Panel + Subpanel + Circuit Breaker + Ground Bar; the owner manual identifies the Home Power Panel as A17B1. It supports 120/240V split-phase, excludes 120/208V, and can connect to either station generation. The manual supports one or two stations, and says its 12-circuit backup load center is required for Backup mode.

Contents conflict to resolve: the current kit title includes a subpanel, while the owner manual labels its 12-circuit backup load center optional. Have the order specify the included subpanel, station cables and installation scope; do not treat a bare panel, a transfer-switch kit and an installed system as interchangeable. Any connection to house wiring needs a licensed electrician and a permit where required.

Independent alternative: EcoFlow DELTA Pro 3

If your loads fit 4,000W continuous, consider DELTA Pro 3: EcoFlow states 4,096Wh, 8,000W surge, 120V/240V output and 2,600W solar input. It has more starting storage than either Anker, but less continuous output; its surge rating is not a substitute for continuous watts.

Buying guide: order the components that solve your problem

Solar and AC recharge limits

For the original, Anker's generation table specifies 11–15V at 10A, or 15–60V at up to 27A, with firmware 2.1.1 or later, still capped at 1,200W per input. The Home Power Panel page retains older 11–32V/10A and 32–60V/25A guidance; the comparison explicitly associates that with firmware 1.7.8 or earlier. Check the installed firmware and exact input specification with Anker before reusing an array.

The Plus instead lists 11–165V, 17A and 1,600W per input. A bundle's panel wattage does not establish compatibility; screen its voltage, current and connectors using our solar panel guide. Generator input is not ordinary AC charging. Anker states 3,300W maximum recharge from a 240V generator for a bare Plus, and advertises 6,000W with expansion batteries.

That is distinct from its 1,800W standard wall input and from the 6,000W bypass ceiling. With that generator connection, the ordinary NEMA 5-20R outlets are disabled; the L14-30R and TT-30R remain available within their published limits. Unresolved accessory wording: the current product title advertises 240V wall-outlet bypass, yet the same adapter page's safety FAQ says not to connect the adapter directly to the grid.

Ask Anker to identify the exact approved accessory and configuration for wall charging before ordering; we do not supply a connection procedure. The Plus page also limits its advertised generator bypass to a single Plus; the adapter FAQ describes an alternative through a Home Power Panel station port. Have the electrician verify which stations can remain connected in your proposed generator arrangement.

Keep a fuel generator outdoors, away from doors, windows and vents, as the CPSC advises.

Stored watt-hours, continuous watts and system maxima

Anker's configuration table gives 3,840Wh / 6,000W for one original station, 7,680Wh / 6,000W with an expansion battery, and 7,680Wh / 12,000W for two stations with the combining equipment. The Plus starts at the same storage and output, and Anker also lists a two-Plus home kit at 7,680Wh / 12,000W. Surge is separate: Anker does not publish a distinct surge rating in these cited tables, so we do not turn its system maximum into an appliance-starting guarantee.
