Head-to-Head · 2026 · Updated November 13, 2026
EcoFlow Delta Pro 3 vs Anker SOLIX F3800 Plus
Both are 120/240V LiFePO4 home-backup stations. The Delta Pro 3 suits homes whose loads stay under 4,000W: it is lighter, has more published surge and rates higher with us. The F3800 Plus is the bigger system, with 6,000W, 3,200W of solar and six expansion batteries per unit. On November 11, 2026, Amazon had it in stock only as a bundle with Anker’s Home Power Panel.

- ✓ You own original Delta Pro extra batteries
Most output and expansion · 90/100
Anker SOLIX F3800 Plus
3,840 Wh, 6,000W at 120/240V and 3,200W of solar in a 136.7 lb unit. Amazon status, November 11, 2026: standalone unit “Currently unavailable”; the bundle with Anker’s Home Power Panel in stock.
- ✓ Your loads go past 4,000W at the same time
- ✓ You plan to grow past 12kWh on one unit
- ✓ You want the station and home panel in one order
Bottom line
This is a choice about size, not quality. Both are LiFePO4, both list 5-year warranties, and both feed a transfer switch through an L14-30R outlet. If your essentials fit under 4,000W and about 12kWh, the Delta Pro 3 does the job in a lighter box and can be bought on its own today. If you need 6,000W at once or a battery bank in the 20kWh range on one inverter, the F3800 Plus is built for that, and this month the in-stock way to buy it is with the Home Power Panel.

Ceilings are the makers’ own figures. The Smart Home Panel 2 price is the panel alone; the Anker price is the station and panel kit together.
Amazon Availability on November 11, 2026
Stock on these systems changes week to week. This is what Amazon’s product data showed when we checked on November 11, 2026.
- EcoFlow Delta Pro 3: in stock, new, sold by Amazon.com.
- Anker SOLIX F3800 Plus (standalone): “Currently unavailable.” We found no Anker statement that the model is discontinued, so we do not describe it that way.
- F3800 Plus + Home Power Panel bundle: in stock, new, sold by AnkerDirect. The listing says the two items ship separately and the kit includes the panel, a subpanel and a ground bar. One bullet on the listing says “F3800” without “Plus,” while the title and box contents say F3800 Plus, so confirm the model on the listing before you order.
- Anker Home Power Panel (alone): “Currently unavailable.”
So the fair comparison this month is the Delta Pro 3 on its own against the F3800 Plus with a panel. If you want automatic switchover anyway, the bundle is a complete Anker setup in one order. If you plan to use a manual transfer switch or interlock, you would be paying for a panel you may not need. In that case the Delta Pro 3, or waiting for the standalone F3800 Plus to come back, is the simpler path.
What the F3800 Plus Does Better
- 2,000W more continuous output. 6,000W vs 4,000W through the L14-30R outlet, per Anker’s spec table. That is the margin that lets a well pump, a furnace blower and a dryer circuit run together.
- More solar, on two matching inputs. Two 1,600W inputs (11–165V, 17A each) for 3,200W, against the Delta Pro 3’s 2,600W split across one high-voltage and one low-voltage input. Matching inputs make it easier to wire two identical strings.
- A much bigger battery bank per unit. Up to six 3,840 Wh expansion batteries, for 26.9kWh on one inverter. A Delta Pro 3 tops out at 12.3kWh with two extra batteries, so to go further you add another unit.
- A panel bundle you can buy today. On November 11, 2026, the station and the Home Power Panel were available together on Amazon. Anker’s panel serves one or two F3800-series stations on a 12-circuit backup load center at 120/240V.
The trade-offs. It weighs 136.7 lb, and each expansion battery adds 72.8 lb, per Anker. Anker publishes no surge figure above 6,000W. Two charging details are easy to miss on Anker’s page. Its 240V output “cannot be used while the device is charging via 120V AC.” And a footnote rates gas-generator and Home Power Panel charging at “3,300W for single unit, 6,000W when working with 1 or more expansion batteries.” For runtime by appliance and its full spec list, see our Anker SOLIX F3800 Plus review.
Where the Delta Pro 3 Wins
- More published surge. 8,000W of surge on top of 4,000W continuous. For one hard-starting motor, such as a well pump or an AC compressor, that published headroom is the figure to check.
- Lighter, and slightly more capacity. 113.5 lb vs 136.7 lb, and 256 Wh more in the base unit (4,096 Wh vs 3,840 Wh).
- Reuses old batteries. EcoFlow’s US manual says the Delta Pro 3 is “backwards compatible with the DELTA Pro Smart Extra Battery.” If you already own original Delta Pro packs, that is a real cost advantage.
- Buy the station alone. It was in stock on Amazon on November 11, 2026, so you can start with a manual transfer switch and add Smart Home Panel 2 later. Up to three Delta Pro 3 units can share one panel, per the manual.
- Our top-rated station. 95/100 in our scoring, the highest in our database.
One manual detail to plan around
On the US Delta Pro 3, the 240V (HV) and 120V (LV) outlet groups have separate buttons that, per the manual, “cannot be used at the same time.” While the L14-30R outlet feeds your transfer switch, the front 120V outlets are off. Put everything on transfer-switch circuits instead of running extension cords from the front. One limit on the Delta Pro 3 side this month: EcoFlow’s Delta Pro 3 extra battery listings showed “Currently unavailable” on Amazon on November 11, 2026.
To connect a Delta Pro 3 to your house (transfer switch, Smart Home Panel 2 or two units on the 50 Amp Hub), see our Delta Pro 3 home backup setup guide. For panel wiring and charge times on its two solar inputs, see the best solar panels for the Delta Pro 3.
Runtime: How Long Each Setup Lasts
Hours at a steady average load, using rated Wh × 0.85 (inverter and conversion losses) ÷ load in watts. Real runtime varies with temperature and how often motors cycle. A dash means the load is above that unit’s continuous output.
| Setup | Capacity | 500W | 1,000W | 2,500W | 5,000W |
|---|---|---|---|---|---|
| Delta Pro 3 | 4,096 Wh | 7.0 h | 3.5 h | 1.4 h | — |
| Delta Pro 3 + 2 extra batteries (per-unit max) | 12,288 Wh | 20.9 h | 10.4 h | 4.2 h | — |
| F3800 Plus | 3,840 Wh | 6.5 h | 3.3 h | 1.3 h | 0.7 h |
| F3800 Plus + 1 expansion battery | 7,680 Wh | 13.1 h | 6.5 h | 2.6 h | 1.3 h |
| F3800 Plus + 6 expansion batteries (per-unit max) | 26,880 Wh | 45.7 h | 22.8 h | 9.1 h | 4.6 h |
Base unit for base unit, the two are close: 3.5 hours vs 3.3 hours at 1,000W. The gaps show up at the edges. Only the F3800 Plus can carry the 5,000W column, and fully expanded it holds more than twice the energy of a fully expanded Delta Pro 3. We use 500W to 1,000W only as a rough planning range for essentials like a fridge, furnace blower, lights and internet. Your own average can be higher or lower, so total your list in the solar size calculator.
Verdict by Use Case
Essentials backup through a manual transfer switch
Delta Pro 3
The pick. 4,000W at 120/240V covers the usual essentials list, the L14-30R matches common 30A transfer switch kits, and the station is sold on its own.
F3800 Plus
Works the same way through its L14-30R, but this month the in-stock listing includes a Home Power Panel you would not use.
Automatic switchover with the brand’s panel
Delta Pro 3
Delta Pro 3 plus Smart Home Panel 2, bought separately: 12 circuits, about 20 ms switchover, up to three units on one panel.
F3800 Plus
The pick if you want it in one order. The bundle pairs the station with the Home Power Panel (12-circuit load center, about 20 ms, indoor install).
Large loads running together (well pump, furnace and dryer)
Delta Pro 3
Tight. If they add up past 4,000W, you need a second unit or a shorter circuit list.
F3800 Plus
The pick. 6,000W continuous, or 12,000W with two units, per Anker.
One hard-starting motor
Delta Pro 3
The larger published margin: 8,000W of surge.
F3800 Plus
No surge figure published above 6,000W. Fine for most pumps, but check the motor’s startup watts.
Big solar array
Delta Pro 3
2,600W across one high-voltage and one low-voltage input.
F3800 Plus
The pick. 3,200W across two matching 11–165V inputs.
Growing the battery bank
Delta Pro 3
Up to 12.3kWh per unit, including original Delta Pro packs. Extra batteries were unavailable on Amazon on November 11, 2026.
F3800 Plus
The pick. Up to 26.9kWh per unit, or 53.8kWh with two units.
Moving it around the house or garage
Delta Pro 3
The pick. 113.5 lb on wheels.
F3800 Plus
136.7 lb on wheels. Plan for it to stay where it is installed.
Both home panels are covered side by side, with EcoFlow’s and Jackery’s other options, in our smart home panel guide.
Not the Right Matchup?
The F3800 Plus is not Anker’s only home-backup station. The smaller SOLIX F3000 is a different model: 3,072 Wh and 120V on its own, with 240V when two units are paired, per its Amazon listing. If your budget points that way, our Anker SOLIX F3000 vs EcoFlow Delta Pro 3 comparison covers that decision. If you are looking up from the Delta Pro 3 within EcoFlow’s range, see Delta Pro 3 vs Delta Pro Ultra. For the two brands’ full lineups, see Anker SOLIX vs EcoFlow.
How We Score These
We do not physically test products. Our ratings come from our 6-dimension scoring matrix (capacity and power, value, solar charging, portability, expandability and battery chemistry), applied to published specs, Amazon listing data and Amazon customer reviews. The Delta Pro 3 (95/100) is the highest-rated station in our database. The F3800 Plus (90/100) leads this pair on output, solar input and expansion, and is the heavier of the two. The Home Power Panel bundle is not rated on its own; the station inside it carries the F3800 Plus score.

Delta Pro 3 vs F3800 Plus: FAQ
Which is better, the EcoFlow Delta Pro 3 or the Anker SOLIX F3800 Plus?
It depends on the job. The Delta Pro 3 scores 95/100 in our scoring against 90/100 for the F3800 Plus. It is lighter (113.5 lb vs 136.7 lb), and on November 11, 2026 it was the one in stock on Amazon as a standalone unit. The F3800 Plus is the bigger system: 6,000W of continuous output vs 4,000W, 3,200W of solar vs 2,600W, and room for six expansion batteries per unit vs two. Pick it if your loads run past 4,000W at the same time or you want a battery bank well past 12kWh.
Is the Anker SOLIX F3800 Plus out of stock?
On November 11, 2026, Amazon showed the standalone F3800 Plus as “Currently unavailable.” The bundle of the F3800 Plus with Anker’s Home Power Panel was in stock that day, sold by AnkerDirect. We found no Anker statement that the model is discontinued, so we do not call it that. Stock changes often, so check the listing.
Does the F3800 Plus have a higher surge rating than the Delta Pro 3?
Anker publishes no separate surge figure for the F3800 Plus. Its spec page lists 6,000W total AC output, and our database uses that same number as its ceiling. EcoFlow lists 8,000W of surge on top of the Delta Pro 3’s 4,000W continuous. In practice the F3800 Plus carries more steady load, while the Delta Pro 3 has the larger published margin for motor starts. Check the startup watts of your well pump or AC compressor against both.
Can both run 120V and 240V at the same time?
There is a limit on each one. EcoFlow’s US Delta Pro 3 manual says the 240V (HV) and 120V (LV) outlet groups “cannot be used at the same time.” Anker’s F3800 Plus page says its 240V output “cannot be used while the device is charging via 120V AC.” Anker does not say whether the F3800 Plus’s 120V and 240V outlets can run together otherwise. On both, the L14-30R outlet carries 120/240V to a transfer switch, so whole-home setups wire every circuit through it.
How far can each one expand?
The Delta Pro 3 takes up to two extra batteries, for 12,288 Wh per unit. EcoFlow quotes 48kWh with three units. The F3800 Plus takes up to six expansion batteries, for 26,880 Wh per unit, and Anker quotes 53.8kWh with two units and 12 batteries. EcoFlow’s manual also says the Delta Pro 3 accepts the original DELTA Pro’s Smart Extra Battery.
Do I need an electrician for either one?
Yes, for anything that feeds your house wiring. Both connect through a transfer switch, an interlock kit or the brand’s home panel. Anker’s Amazon bundle listing says the Home Power Panel needs professional installation by a licensed electrician and a 100A breaker sold separately. The CPSC warns that backfeeding a house through an outlet is dangerous. Plugging appliances straight into either station needs no installation.
