Anker SOLIX F3800 Plus
The short answer
This is a 3,840Wh battery with 6,000W of output, which means it stores about 3,264 watt-hours you can actually use and can run anything drawing up to 6,000 watts at once.
It runs indoors and makes no fumes. Of the 15 household loads we track, it can handle 16. It would keep a refrigerator going for 4.7–32.6 hours.

Power and battery figures published by the maker. We have not yet researched the rest of this model.
Judged in: The home-backup class: DELTA Pro 3, SOLIX F3800, Explorer 5000 Plus and the rest (compared); Anker SOLIX F3800 vs F3800 Plus: the real differences.
Specifications only
We have the maker's power and battery figures, so the planner can size it. We have not yet checked the manual, the solar and wall-charging limits, extra batteries, the warranty, the official add-ons, or safety recalls.
Treat this as a model to research, not one we vouch for. The fully researched models have all of that.

Living with it
What the maker’s own pages and manual say about owning this unit, and what owners report in public. Each line links to where it was read. Nothing here is our own test.
- Switchover when the grid drops
- 20 ms UPS switchover on normal 120V wall AC power (spec table + FAQ Q5 condition for '120V Wall Outlet, No Generator'); separately, FAQ Q5 gives different switching times for generator scenarios: F3800 Plus-to-Generator 30 ms, Generator-to-F3800 Plus 50 mssignaturesolar.com
- Pass-through charging
- Yes, bypass/pass-through charging is supported. On 120V wall AC alone, bypass is capped at 1,440W and only the 3 UPS-designated NEMA 5-20R outlets remain usable while recharging (FAQ Q9). Via a 240V generator (through the Home Power Panel + Generator Input Adapter), bypass limits rise to 3,000W on the TT-30R port or 6,000W on the L14-30R port, and the 120V outlets remain usable (FAQ Q10).signaturesolar.com
- AC input
- 1,800W max AC input for charging via 120V wall outlet; rated AC input current is 15A max for under 3 hours or 12A max continuous at 120V/60Hzsignaturesolar.com
- USB-C
- 3x USB-C ports, 100W max each (5V/3A, 9V/3A, 15V/3A, 20V/3A, or 20V/5A profiles); output only, cannot be used to charge the unit (FAQ Q3)signaturesolar.com
- Outlets and ports
- 6x NEMA 5-20R 120V outlets in two groups of 3 (2,400W max per group; the 3 leftmost have UPS); 1x NEMA TT-30R 120V outlet (3,000W max); 1x NEMA L14-30R 120V/240V outlet (6,000W max, also used for EV charging); 2x USB-A (12W max each); 3x USB-C (100W max each, PD, output only); 1x 12V/10A car socket; 1x Home Power Panel port (6,000W max AC in and out); 2x solar input ports (1,600W max each, 3,200W combined, 11-165V/17A max each); 1x expansion battery port; 1x Anker SOLIX Smart Generator portsignaturesolar.com
- Charges between
- 0°C to 40°C (32°F to 104°F) while charging, per the manual's headline spec row; a separate charging-power-vs-cell-temperature table in the same manual (0-10°C: 760W max; 10-15°C: 1800W/2000W max; 15-50°C: 1800W/3300W max) implies the unit will still accept a charge somewhat above 40°C at rated power, so the 0-40°C figure should be read as the primary/labeled spec rather than an absolute cutoffsignaturesolar.com
- Runs between
- -20°C to 40°C (-4°F to 104°F) while discharging/in usesignaturesolar.com
- Cycle life
- 3,000+ cycles (LiFePO4/LFP cell, maker claim); marketing copy elsewhere on the same page separately claims '10 Years of Everyday Power'ankersolix.com
- Low-load shutoff
- Powers itself off automatically after about 12 hours with outputs off and no load detected; standby duration is adjustable in the Anker app. Separately, the AC outlet button itself auto-off after 15 minutes by default if no AC plug insertion is detected, and USB ports stop charging after 2 hours below 60mAsignaturesolar.com
- App
- Yes, via the Anker app (iOS App Store / Google Play) over Wi-Fi and Bluetooth, toggled with the unit's IoT button; supports real-time monitoring of charging/usage/battery status and remote control (including setting AC charging power, auto-off timers, and standby duration)ankersolix.com
- Expansion
- Supports up to 6x Anker SOLIX BP3800 expansion batteries (3.84kWh each), increasing total capacity up to 26,880Wh (26.88kWh)ankersolix.com
- Size
- 27.6 x 15.3 x 15.6 in, including wheels (70.2 x 38.8 x 39.5 cm per the manual)ankersolix.com
- Weight
- 136.7 lb per the maker product page; note the official user manual PDF states 61.5 kg / 135.6 lb for the same unit -- a roughly 1 lb discrepancy between two maker-owned sources, both cited hereankersolix.com
- Warranty

What owners report, from public threads and long-term reviews; not our own testing.
- Two independent hands-on reviewers (The Solar Lab and AppleInsider) both flag the roughly 136-137 lb weight as a real practical limitation for a unit still marketed as 'portable' -- AppleInsider's reviewer needed help getting it down stairs, and The Solar Lab notes solo carrying over any distance isn't practical despite the locking caster wheels, telescoping handle, and hidden carry handles.appleinsider.com
- AppleInsider's tester measured noise at roughly 60 dB under heavy load while describing overall operation as 'whisper-quiet' during normal use.appleinsider.com
- The Solar Lab reports the Plus's upgraded 3,200W-rated solar input is a real, measurable improvement over the base F3800, which they say struggled to hit even 1,600W in real-world testing despite its 2,400W theoretical rating -- the Plus reportedly charges reliably at its rated speed with standard MC4 panels.thesolarlab.com
- AppleInsider's reviewer found battery standby/charge retention improved versus the original F3800, saying they 'rarely' needed to top off the unit between uses, and described the Anker app as straightforward for checking battery status and power allocation, though remote monitoring requires the unit to already be powered on.appleinsider.com
- The Solar Lab reports the TT-30R port is commonly marketed/read as a '30A' outlet but is technically rated 25A, which could cause stuttering or underperformance with appliances or RV connections expecting true 30A service.thesolarlab.com
- The Solar Lab says Anker dropped the base model's XT-60 solar connectors on the Plus in favor of MC4, so owners with existing Anker solar panels/cables need adapters despite the page's MC4-compatibility claims.thesolarlab.com
- The Solar Lab reports the unit alone tops out around 3,500W of AC+solar input; hitting the full 6,000W combined charging rate requires two expansion batteries attached (one battery raises it to roughly 4,500W), and the expansion-battery connection cables are described as long, floppy, and awkward rather than a clean stacking connection.thesolarlab.com
- AppleInsider's review states the Plus dropped the L14-50R EV charging port used on an earlier/other configuration in favor of the L14-30R/TT-30R combination -- flagged here as a review claim only, since it appears to conflict with the manufacturer's own manual, which documents EV charging via the L14-30R port (not an L14-50R) on this unit; treat this specific point as unresolved between sources.appleinsider.com
