Detailed overview: Anker SOLIX F3800
The Anker SOLIX F3800 is a premium portable power station built for home backup and heavy energy demands. It runs on a 3840Wh LiFePO4 battery and delivers a continuous 6000W output (9000W peak), enough to run a home's most demanding appliances at once: an oven, a washer, a well pump or a portable air conditioner.
What sets the US version apart is genuine 120V/240V split-phase output. Alongside six standard 120V NEMA 5-20 outlets, it carries a NEMA 14-50 and a NEMA L14-30 receptacle, the same outlet styles used for EV chargers, large RVs and generator transfer switches, either one alone able to deliver the full 6000W. That makes it one of the few portable stations able to directly power 240V equipment like a well pump or a large workshop tool, without a separate step-up device.
Its real strength is expandability. Adding up to six Anker SOLIX BP3800 batteries (3840Wh each, hot-swappable without interruption) takes a single unit's capacity up to 26.9kWh. Linking two F3800 units together reaches 53.8kWh and 12,000W, close to a genuine home energy storage system. This modularity lets you size the setup to your actual needs, without buying a whole new unit at every step.
On charging, the F3800 accepts up to 1800W from a standard wall outlet and up to 2400W from solar, spread across two independent MPPT inputs, useful for topping up a large reserve quickly on a sunny day. Its UPS function switches over in 30ms, fast enough for most sensitive household electronics.
Mounted on wheels with a telescoping handle, it stays movable despite its 60kg (132 lb) weight. The LiFePO4 battery is rated for over 3000 cycles at 80% remaining capacity, backed by a 5-year manufacturer warranty. The Anker app, over Wi-Fi and Bluetooth, lets you monitor charging and consumption remotely.
One point worth knowing: for full electrical integration into a home's breaker panel with automatic whole-house switchover, a separate transfer switch is still required. Without it, it powers your devices through its own outlets like any large portable power station. For anyone after a massive, expandable energy reserve with real 240V capability, the F3800 remains a benchmark in its class.

What is this power station best for?

Home & Power cuts Ideal
With 3840Wh, a true 6000W continuous output and 9000W peak, the Anker SOLIX F3800 handles a home's most demanding appliances during an outage without flinching: oven, washer, well pump or a portable AC unit. It's one of the few portable stations delivering genuine 120V/240V split-phase power, through a NEMA 14-50 and a NEMA L14-30 outlet, either one alone capable of the full 6000W, alongside six standard 120V NEMA 5-20 outlets. Its UPS function switches over in 30ms, fast enough for most sensitive electronics. Up to six hot-swappable Anker SOLIX BP3800 batteries take a single unit to 26.9kWh, and linking two F3800 units reaches 53.8kWh at 12,000W, enough for a multi-day outage. For automatic whole-panel switchover, a separate transfer switch is still required.
-
Off-grid & Solar Suitable
With solar input up to 2400W across two independent MPPT trackers and expandability up to 26.9kWh per unit (53.8kWh linking two), the F3800 works as a real building block for a cabin, workshop, or off-grid property. Its 6000W output, with genuine 240V availability through its NEMA 14-50 and L14-30 outlets, covers well pumps and other 240V equipment that trips up most portable stations limited to 120V only. The LiFePO4 cells are rated past 3000 cycles at 80% remaining capacity, and the Anker app tracks generation and consumption remotely. Panel count and battery expansion should be sized to the site's real seasonal needs.
-
Job site & Tools Suitable
Its 6000W continuous (9000W peak) starts and runs demanding site tools without issue: table saws, air compressors, welders, with eight total outlets including two dedicated 240V ports (NEMA 14-50, NEMA L14-30) for equipment that needs it, not just 120V. Its 3840Wh, expandable to 26.9kWh with BP3800 batteries, covers a long, tool-heavy day, and solar input up to 2400W recharges on site with no fumes or noise. At 60kg (132 lb), the wheels help with positioning, though it's best kept at a fixed spot rather than moved constantly between sites.
-
Motorhome & Van life Suitable
Mounted on wheels with a telescoping handle, the F3800 rolls like an oversized suitcase despite its 60kg (132 lb) weight, a real plus for an RV with a dedicated bay. Its 6000W runs a rooftop AC, an induction cooktop or a water heater without restriction, and solar input up to 2400W across two MPPT trackers recharges fast at a sunny stop. Expansion with BP3800 batteries can stretch autonomy to several days for a large rig. Its weight and footprint make more sense for a Class A or fifth-wheel with a permanent spot than a small camper van.
-
Events & Market stalls Backup only
Its 6000W and eight outlets, including two 240V ports, can cover an outdoor event's sound, lighting and catering equipment without generator noise or fumes. But at 60kg (132 lb) and built primarily as a fixed home-backup reserve, it's less practical to shuttle between venues than a lighter, purpose-built event station, and its price is easiest to justify when it already does double duty as a home backup unit.
Our team's recommendations based on the model's capacity, output power and weight.
Comparison
Priced at roughly $2,000 (frequently discounted from a higher list price), the Anker SOLIX F3800 competes with the largest expandable power stations built for serious home backup. Here is how it stacks up against two direct alternatives: the EcoFlow Delta Pro 3 and the EcoFlow Delta Pro Ultra.
| Criterion | Anker SOLIX F3800 | EcoFlow Delta Pro 3 | EcoFlow Delta Pro Ultra |
|---|---|---|---|
| Capacity (base) | 3840Wh | 4096Wh | 6144Wh |
| Power output | 6000W | 4000W | 7200W |
| 240V outlets | NEMA 14-50 and L14-30 | NEMA TT-30/L14-30 (bundle-dependent) | NEMA 14-50 |
| Max expansion (1 unit) | 26.9kWh | 12.3kWh | 30.7kWh |
| Price observed | ≈ $2,000 | ≈ $2,799 | ≈ $4,199 |
The Anker SOLIX F3800 stands out with the best power-to-price ratio in this comparison: its 6000W output comfortably beats the Delta Pro 3 at a noticeably lower price, and while the Delta Pro Ultra pushes higher power and expansion, it costs more than double. Its fine expansion steps of 3.84kWh each also allow precise sizing of the investment to actual needs, and its dual 240V outlets are a genuine edge for anyone needing to run well pumps or large shop tools directly.

Our tester's review: Christophe Delpuech
We used the Anker SOLIX F3800 as a home backup source, and the first thing that stands out is the pair of 240V outlets: a NEMA 14-50 and a NEMA L14-30 mean this thing can genuinely run a well pump or a large window AC unit that would trip up most 120V-only portable stations. The full 6000W is real, not a marketing peak number stretched thin. Wall charging is fast enough day to day, though it tops out at 1800W, so a full charge from empty takes longer than the 240V output numbers might suggest. The wheels and telescoping handle earn their keep given the 60kg (132 lb) weight, though once it's in position you rarely move it again. The BP3800 expansion batteries let you start at 3840Wh and scale up over time as budget allows, a genuine step-by-step investment rather than an all-or-nothing purchase. Two honest caveats: the price climbs fast with each expansion battery, and a proper automatic whole-panel switchover still needs a separate transfer switch, this powers your gear through its own outlets, not your house wiring directly. For a large, expandable home energy reserve with real 240V capability, it's one of the more capable options in its class.

Yes. Unlike most portable power stations limited to 120V, the F3800 has a NEMA 14-50 and a NEMA L14-30 outlet, either one alone able to deliver the full 6000W at 240V, alongside six standard 120V outlets. That covers equipment like well pumps or large shop tools that need a 240V circuit.
On a standard wall outlet it accepts up to 1800W. It also accepts up to 2400W of solar input across two MPPT trackers for a faster top-up on sunny days.
Adding up to six Anker SOLIX BP3800 batteries (3840Wh each) takes a single unit to 26.9kWh. Linking two F3800 units together raises capacity to 53.8kWh at 12,000W.
With 6000W, true 240V output and expandability up to 26.9kWh, it covers most household needs, including some 240V appliances. A separate transfer switch is required for automatic switchover across a full breaker panel.
It weighs 60kg (132 lb), but sturdy wheels and a telescoping handle let one person move it like an oversized suitcase. Plan for two people when lifting it into a vehicle.
