Review · Anker SOLIX F3800
Buy it when 240 V is the point and you will treat 3,840 Wh as a tank you can grow. Skip it when a fridge-and-router 120 V station would have been enough.
Summary
The Anker SOLIX F3800 review in three figures: 3,840 Wh of LFP capacity, 6,000 W continuous with a 9,000 W surge, and 120/240 V split-phase output, at $2,199.98 on the manufacturer page August 26, 2026. That voltage line is the reason this 132.3 lb cabinet exists. The sections below cover what those figures run, what they weigh, and what we are not claiming.
Two figures put this machine in the home-battery silo: 120/240 V output and 6,000 W continuous. Everything else on the plate follows from them. This is a named-SKU review, not a category trophy; The Home Backup lists the Anker SOLIX F3800 because it is the split-phase machine in the ledger, with an official manufacturer photograph. Tesla Powerwall is out of scope. Rooftop solar is out of scope. We do not invent outlet counts, solar-input watts, or extra-battery SKU names that are not on our dated spec sheet.

Nameplate capacity is 3,840 Wh; plan runtime as if you will not empty the pack to the floor. A fridge that averages 150–250 W while cycling takes on the order of 1–2 kWh per day. Lights and a network stack are small. A 1,500 W space heater is a short evening. That ratio is the category in one line: more inverter than a portable station carries, and still a tank.
Continuous output is 6,000 W; surge is 9,000 W. Those are Anker’s listed numbers as of August 26, 2026. Locked-rotor current on a well or a compressor can still exceed what a given house will start, so test the load; 9,000 W is a rating, not a promise that every 240 V motor in the county will spin. Voltage is 120/240 V, and that one line is why this review sits in the home-battery silo instead of the ~2 kWh 120 V aisle.
Street price on the manufacturer page that day: $2,199.98, with no list price struck against it. Sales move; confirm live. Affiliate hop: See F3800 price. Same price to you. Disclosure.
132.3 lb is the figure that decides placement. Casters work on a flat slab; they do not work on a stair. Two people and a plan beat one person and an estimate. Keep the cabinet dry, out of the standing water a weeping water heater leaves, and clear enough on all sides that the fans are not fighting a closet.
In form this is still a portable-class product: a tall gray wheeled cabinet, not a pad plant and not a wall-mounted ESS. It rolls; it does not travel. For reference, the Explorer 2000 Plus weighs 61.5 lb and the AC200L 62.4 lb; the F3800 is the one that stays where you put it.
The job, in one line: split-phase home hook. Heavy. Not a pad generator. That is the review, compressed. The comparison page that sits this SKU next to the 120 V cores is best expandable home batteries.
Expandable: yes. We do not invent the companion battery’s retail name. Extra kilowatt-hours stretch a 240 V must-list; they do not raise 6,000 W continuous to whole-home HVAC. If the house must behave like the grid for days, read battery vs standby and then the generator cost page.
Wall charging is how you recover between flickers; portable solar is how you recover when the utility stays down in daylight. Anker’s folding panel in this ledger is the SOLIX PS400 (400 W nameplate, 35.3 lb, IP67; Voc is a dash because Anker's pages never settle on one figure). Confirm the F3800’s solar input window on the live Anker page before you series-wire anything. Do not guess Voc.
We have not personally cycled an F3800 through a winter in a lab we own. This review is job-based plus the dated manufacturer ratings we can stand behind. We do not claim cycle counts we did not measure. We do not claim the cabinet is quiet in every fan curve. We do not claim it replaces a 20 kW liquid-cooled standby.
EcoFlow sells large expandable stations; they are not featured here because a 7-day cookie is a poor fit for this research cycle. We will not round out the page with a fake generator affiliate. If Anker’s live page disagrees with a number above on the day you buy, the live page wins.
The flip condition: every must-list load turns out to be 120 V. Then the decision reverses to a ~2 kWh core and the split-phase inverter goes unused. Otherwise, the plate stands.
Finite kWh. Heavy. Electrician for the house hook. Not Powerwall. Not a roof. Method: how we review. Lighter 120 V Anker in the portable aisle: C2000 Gen 2. Shop: Anker SOLIX.
Silo hub: home batteries. Circuit math: buying guide. Corrections: contact.
