Anker SOLIX F3800 Plus + 400W panel review: a 240 V home battery with a first panel for multi-day outages

This is a research-based review, based on manufacturer specs and published data. We do not test products. Figures come from Anker's F3800 Plus with 400W Bifacial Solar Panel bundle page, its F3800 Plus product page and its PS400 bifacial panel page, checked November 1, 2026, and from the federal sources cited below.

The battery in this bundle is covered in full in our Anker SOLIX F3800 Plus review: 3,840 Wh, 6,000 W at 120/240 V, and up to 3,200 W of solar input. This review covers what the bundled panel adds. Anker's bundle page describes it only as a 400 W bifacial panel and does not print its specs, so we use Anker's PS400 bifacial panel page, its 400 W bifacial folding model, for panel figures. Confirm the panel model on the listing before you buy.

Anker's own store listed the bundle as sold out on November 1, 2026. Availability elsewhere may differ.

Who should buy it

• Households buying an F3800 Plus for 240 V backup that want one cable and one panel matched from the start.
• Homes in storm or wildfire shutoff areas where outages run several days and fuel can be scarce.
• Buyers who want a folding panel they can set out on a patio and put away, not a roof installation.

Who should skip it

• Anyone expecting one panel to refill 3.84 kWh. On our planning math it puts back about 1,200 Wh on a clear day.
• Households that need only a fridge and electronics covered. The Jackery Solar Generator 2000 v2 pairs 2 kWh with 400 W of panels at a fraction of the weight.
• Buyers already set on a large panel array. Buy the station alone and size the array to its two 1,600 W inputs.

Strengths

• Bifacial gain. Anker says the PS400's two-sided design can add up to 10% more power from light reflected onto the back.
• High-efficiency cells. Anker lists 25%+ conversion efficiency from N-type cells on the PS400.
• Lighter than many 400 W folding panels. 21.9 lb on Anker's spec table.
• Huge headroom. The station's two inputs each take 11 to 165 V and up to 1,600 W, so you can add panels without changing the battery.
• IP68 panel with a 5-year warranty per Anker's PS400 page.

Drawbacks

• One panel is about 13% of the input. 400 W against a 3,200 W ceiling.
• Panel specs are not on the bundle page. Anker's bundle listing names only a 400 W bifacial panel.
• Fixed tilt. Anker's PS400 page recommends a 35-degree stand angle with only slight adjustment.
• Rain caution. Despite the IP68 rating, Anker's FAQ advises against use in heavy rain or submersion.
• The station still needs an electrician to feed home circuits through a transfer switch, inlet box or Anker's Home Power Panel.

How it compares

Using it in a long outage

What one 400 W panel delivers

Assume about 4 peak sun hours on a clear day in much of the US, fewer in winter or cloud (our planning assumption; check your location). 400 W × 4 hours is 1,600 Wh at the panel. After losses from heat, angle and charging, call it about 1,200 Wh into the battery. Bifacial gain may add a little over light-colored ground. A refrigerator rated at 400 kWh a year uses about 1,100 Wh a day, so on a clear day the panel roughly covers the fridge.

The battery covers everything else. With about 3,260 Wh usable (85% of 3,840 Wh, our planning figure), a fridge plus 300 Wh of lights, router and phones draws about 1,400 Wh a day, mostly offset by the panel in good weather. A well pump, furnace blower or central air changes that quickly. Each extra 400 W panel adds about another 1,200 Wh on a clear day; at the station's 3,200 W limit, a good day could refill the whole battery.

Daily solar routine

1. 01Set the panel out by mid-morning at Anker's recommended 35 degrees, facing the sun.
2. 02Keep it clear of shade and re-aim it toward the sun every couple of hours.
3. 03Keep the station indoors and dry, and run the cable through a door or window gap.
4. 04Shift laundry, pump refills and other heavy loads to midday.
5. 05Fold the panel away at night and before heavy rain or wind.
