The verdict

The F3800's party trick is 6000W of split-phase power from one portable box — the only station here that can directly feed 240V loads and meaningfully add miles to an EV. On sale under ~$2,200 it undercuts every rival on watts per dollar.

What we like

  • 6000W dual-voltage output — runs dryers, well pumps and 240V tools from one box
  • Direct EV charging via NEMA 14-50, plus RV-ready TT-30
  • Expands to 26.9kWh (53.8kWh with two units) for week-long outages
  • Deep sale discounts make it the value flagship when priced under $2,200

Watch out for

  • 132 lb — the heaviest single unit we track
  • List price is misleading; only buy on sale

The Anker SOLIX F3800 is the watts-per-dollar flagship: 3840Wh of LFP storage behind a 6000W split-phase inverter — the only portable box here that speaks 240V natively. Dryers, well pumps, EV mobile connectors and RV 50-amp service all plug straight in.

Who the F3800 is for (and who should skip it)

Buy it if you have 240V loads, want to trickle-charge an EV during outages, or want the deepest expansion path in the category (26.9kWh per unit). At sale prices under ~$2,200 it’s also simply the cheapest way to buy 6000W of inverter.

Skip it if you need portability — 132 lb is the heaviest single unit we track, wheels or not. Skip it at list price; the $3,999 MSRP is fiction and the street price is the real price. And skip it if your backup plan is a single-day outage with a fridge: this much inverter is wasted there — the Anker SOLIX F3000 or EcoFlow DELTA Pro 3 fits better.

Output: in a class of one

6000W continuous with 9000W surge, delivered as 120V/240V split-phase. No other portable station here does this from one box — the DELTA Pro 3 tops out at 4000W/120V (240V needs two units). Six 20A 120V outlets plus NEMA 14-50 and L14-30 cover every plug type a North American home or RV uses.

Real-world runtime examples

Usable capacity is ~85% of 3840Wh, about 3264Wh:

  • Full-size fridge (~150W avg): ~21 hours.
  • Window AC (~1000W): ~3.2 hours of cooling per charge.
  • Well pump (750W cycling): ~4 hours of actual pump runtime.
  • Space heater (~1500W): ~2.2 hours — high-draw heat eats any battery fast, which is why the 6000W inverter matters: it can at least run the heater, unlike smaller boxes that just trip.

Battery and expansion

The 3840Wh LFP pack is rated for 3000+ cycles (10+ year lifespan per Anker) and carries a 5-year warranty. Expansion is the deepest here: up to six BP3800 batteries (26.9kWh), or 53.8kWh with a second F3800. That’s week-long outage territory with solar help.

Solar and recharge

2400W of dual-MPPT solar input refills 0–80% in about 1.5 hours of strong sun with a big array. AC wall charging is slower (1800W max) — this is a solar-first machine. In practice, four 400W panels (~1400W real-world) refill the base unit in about 2.5 peak sun hours. Storm Guard mode in the Anker app watches weather alerts and tops the battery up automatically.

How it compares

Against the DELTA Pro 3: Anker wins on output watts and sale pricing; EcoFlow wins on solar input speed per dollar and app polish. Against the Jackery Explorer 2000 Plus: Anker wins on raw power and 240V; Jackery is quieter and starts cheaper at 2kWh. Our station vs generator guide puts the F3800 head-to-head with gas on 5-year cost, and our outage scenarios show where 6kW actually matters.

EV and RV use cases

The NEMA 14-50 outlet is the F3800’s party trick: plug a mobile EV connector into it and add roughly 15–25 miles of range per hour — enough to turn a dead-EV panic into a manageable afternoon. For RVs, the L14-30 outlet feeds 50-amp shore-power service directly, and 6000W runs the air conditioner plus everything else at once. These aren’t marketing extras; they’re the reason to pick this box over 120V-only rivals.

What to buy with it

Budget for panels before expansion batteries. Four 400W rigid panels (~$600 street) use barely half the 2400W solar input and refill the base unit in about 2.5 peak sun hours. The expansion batteries are where the real money goes — watch for bundle sales, which often discount packs 20–30% when bought with the main unit.

SOLIX F3800 FAQ

Can the Anker SOLIX F3800 power 240V appliances?
Yes — it's the only station we track with 6000W of split-phase 120V/240V output from a single unit, via NEMA 14-50 and L14-30 outlets. That covers electric dryers, well pumps and 240V power tools.
Can the F3800 charge an EV?
It can add meaningful range: the NEMA 14-50 port delivers up to 6000W to a mobile EV connector, roughly 15–25 miles of range per hour depending on the vehicle. It's an emergency/range-anxiety tool, not a daily charging solution.
How far does the F3800 expand?
Six BP3800 expansion batteries take one unit to 26.9kWh; two F3800s in parallel reach 12kW/53.8kWh — a genuine whole-home system.
What does the F3800 actually cost?
List is $3,999, but US street prices routinely fall to $1,800–$2,200 on sale. Never pay list — set a price alert and wait.
Can the F3800 run central air conditioning?
Window units and mini-splits, yes — the 6000W inverter handles most of them. Central AC (typically 3,500W+ running) is a maybe at best: the startup surge often trips even this unit. Size for it only with expansion batteries and realistic expectations.
Is the F3800 safe to use indoors?
Yes — LiFePO4 chemistry with no emissions, unlike gas generators. Just keep vents clear, don't block the fans, and follow the usual clearance rules for a 6000W inverter under heavy load.
