Anker SOLIX F3800 Plus review: price, 240V output, expansion and home backup kits (2026)

The Anker SOLIX F3800 Plus is a home battery on wheels: 3,840Wh of storage, 120V and 240V output up to 6,000W, and room for expansion batteries. This Anker SOLIX F3800 Plus review covers what it costs, what it can run, how it connects to your home and where it falls short. In short: it is a strong choice if you need 240V or want to back up several circuits, but it is heavy and expensive, and the full system costs well above the base price.

We built this review from Anker’s US product page, its F3800 Plus collection page and its expansion battery bundle page, all read on 17 October 2026. We have not used the unit ourselves, so the page is labeled as researched. See how we research and rate products.

What the Anker SOLIX F3800 Plus is and who it’s for

The F3800 Plus is a large LFP battery with a split-phase inverter, so it can supply both 120V and 240V. You can use it on its own with its eight outlets, or connect it to your home’s electrical panel through a transfer switch or Anker’s Smart Home Power Kit.

It suits homeowners who want to keep a well pump, furnace, fridge and lights running for a day or more, people with an RV that uses a TT-30 plug, and anyone planning to add solar panels. It is overkill for an apartment that only needs Wi-Fi and a fridge.

Anker SOLIX F3800 Plus specs

Anker’s page lists the expansion limit two ways. One line says “expandable to 53.8kWh (12kW)”. That matches two F3800 Plus units with six batteries each (Anker sells a Double Power Hub to link two units). One unit with six batteries is 26.9 kWh, which is also the figure on Anker’s expansion battery page. Anker did not list a surge rating.

Anker SOLIX F3800 Plus features for home backup

240V output. The L14-30R outlet supplies 120/240V at up to 6,000W. That is what most 1 to 2 kWh power stations lack, and what you need for many well pumps, a dryer or a home connection.

Big solar input. Two ports take up to 1,600W each at up to 165V, for 3,200W in total. Anker says a full solar recharge takes under 2 hours in one place and 1.5 hours in another, so expect about 2 hours in full sun with the maximum array.

Generator pass-through. It can be charged from a 240V gas generator. Anker’s footnote says 3,300W for a single unit and 6,000W when it works with one or more expansion batteries.

Remote control. The Anker app connects over Wi-Fi or Bluetooth. Anker’s Storm Guard and Local Energy Saver features need its separate Home Power Panel.

Anker SOLIX F3800 Plus price and bundles (2026)

On 17 October 2026 Anker’s US collection page listed:

The page showed one price per bundle, with no crossed-out regular price. The 3-battery bundle was marked sold out on its own page. At $2,999.99 the base unit costs about $0.78 per watt-hour, close to the EcoFlow DELTA 3 Plus, and the expansion battery bundle brings that to about $0.65.

How the F3800 Plus connects to your home

You have three routes, all from Anker’s bundles:

1. Plug in directly. Run appliances from its eight outlets with extension cords. No installation needed.
2. 10-circuit manual transfer switch. An electrician wires the switch next to your panel, and you choose up to 10 circuits to run from the battery.
3. Smart Home Power Kit. Anker describes it as connecting the battery with the utility grid and rooftop solar. Anker also sells it with an installation service.

Anker’s page calls the system “plug-and-play, no electrician needed” in general terms. Any connection to your home’s wiring should still be installed by a licensed electrician, and your local code may require a permit.

What can the Anker SOLIX F3800 Plus run during an outage?

We plan with a 15% margin for inverter losses, so about 3,260Wh of the 3,840Wh is usable:

• A fridge averaging 70W (an example, measure yours): about 46 hours
• That fridge plus a 20W router and 40W of LED lights: about 25 hours
• A furnace blower drawing 400W (an example, check yours): about 8 hours of blower run time
• With one expansion battery (7,680Wh): roughly double each figure

For smaller loads, a 1 to 2 kWh unit is cheaper. See our list of the best portable power stations for home backup and our guide to the best portable power station for a refrigerator.

Who should skip the Anker SOLIX F3800 Plus

Skip it if you rent or cannot connect it to your home’s wiring: you would pay for 240V you cannot use. Skip it if you need to move it often, because at 136.7 lb it rolls on wheels but will not go up stairs easily. And skip it if your outages last a few hours and you only need a fridge and Wi-Fi: the EcoFlow DELTA 3 Plus or a Jackery Explorer 2000 v2 costs a fraction of the price.

Is the Anker SOLIX F3800 Plus worth it?

For homeowners who need 240V, want to back up chosen circuits, or plan big solar input, yes. It offers 3,840Wh, 6,000W at 120/240V, 3,200W of solar and expansion to 26.9 kWh, with a 5-year warranty. Budget for the transfer switch and an electrician on top of the base price, and check today’s bundles on Anker’s F3800 Plus page.
