The F3800 is a split-phase house hook in a 132.3 lb cabinet. It is not a silent Powerwall and it is not a pad generator.

Updated August 26, 2026 · The Home Backup

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 our catalog 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.

Capacity, output, and surge

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 might take 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 is the whole personality of a home battery: lots of inverter relative to a portable station, 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 on a well or a compressor can still exceed what a house will actually start. Test the load. Do not treat 9,000 W as a promise that every 240 V motor in the county will spin. Voltage is 120/240 V — that is why this review lives in the home-battery silo instead of the ~2 kWh 120 V aisle.

Street price on the manufacturer page that day: $2,199.98. No compare-at listed in our catalog. Sales move. Confirm live. Affiliate hop: See F3800 price. Same price to you. Disclosure.

1. Confirm 240 V is required. If not, you are paying for an inverter class you will not use.
2. Write the must-list watt-hours for the outage length you actually get.
3. Budget the electrician if wall circuits are the point — see the buying guide.
4. Plan recharge (wall AC, then panels) before you assume extra modules will save a sunless week.
5. Weigh 132.3 lb against the route from the truck to the basement.

Weight and where it lives

132.3 lb is the number. Casters help on a flat slab. They do not help on a stair. Two people and a plan beat a hero carry. Keep it dry. Keep it out of standing water next to a water heater that weeps. Keep airflow around the cabinet so fans are not fighting a closet.

This is still a portable-class product in form: a tall gray wheeled cabinet, not a pad plant and not a wall-mounted ESS. You can, in principle, roll it. You will not toss it in a hatchback for a weekend if you also value your suspension. Compared with the 61.5 lb Explorer 2000 Plus and the 62.4 lb AC200L, the F3800 is the one that stays where you put it.

Expanding and recharging

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 you need the house to 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 our catalog is the SOLIX PS400 — 400 W nameplate, 35.3 lb, IP67, Voc left blank because manufacturer pages conflicted or were unclear. Confirm the F3800’s solar input window on the live Anker page before you series-wire anything. Do not guess Voc.

• 3,840 Wh nameplate, LFP, street $2,199.98 on August 26, 2026.
• 6,000 W continuous, 9,000 W surge, 120/240 V.
• 132.3 lb. Casters, not a camping carry.
• Expandable yes — extra kWh, same inverter class.
• Legal inlet or transfer switch if it touches house wiring.

What we are not claiming

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.
