Pros and cons
EcoFlow DELTA Pro 3 Portable Power Station
The pick for backing up a whole house: 4 kWh in one unit, real 240 V output and room to grow to 12 kWh. If you need more solar input or 6,000 W from a single unit, look at the Anker SOLIX F3800 Plus.
Pros
- 4,096 Wh and 4,000 W continuous at 120 V or 240 V from one unit, with a 240 V L14-30R outlet for a transfer switch
- Up to 2,600 W of solar input across two ports
- 4,000 cycles to 80% capacity and a 10 ms backup switchover, by EcoFlow's figures
- Grows to 12 kWh with two Smart Extra Batteries, more with EcoFlow's home panel
Cons
- 113.5 lb: it rolls on wheels, but it is heavy to lift into a vehicle
- EcoFlow's 0-80% in 50 minutes figure does not say which input it assumes; a standard 120 V, 15 A outlet can supply at most 1,800 W
- Wiring it into the house needs EcoFlow's Smart Home Panel 2 or a transfer switch, installed by an electrician
- The full 5-year warranty needs registration in the EcoFlow app; the standard warranty is 3 years
Anker SOLIX F3800 Plus Portable Power Station
The whole-home station for big solar arrays and generator owners: 3,200 W of solar and 6,000 W of output. If you want a lighter unit with a longer published cycle life, the EcoFlow DELTA Pro 3 is the better buy.
Pros
- 3,200 W of solar input: the most of any station we cover, by the makers' figures
- 6,000 W of total AC output at 120 V and 240 V from one unit
- Passes up to 6,000 W from a 240 V generator with Anker's Generator Adapter
- Takes up to six BP3800 expansion batteries
Cons
- 136.7 lb, the heaviest station we cover
- Anker rates the battery for 3,000+ cycles without saying to what capacity
- Wall charging from a standard 120 V outlet is capped at 1,800 W
- Anker's FAQ gives a 20 ms switchover, slower than the 10 ms of the EcoFlow DELTA Pro 3
Choose the EcoFlow DELTA Pro 3 if
- You want the most stored energy in one unit and the lighter of the two.
- You care about a published cycle rating: EcoFlow gives 4,000 cycles to 80%.
- Sensitive electronics are on the backup circuit and you want a 10 ms switchover.
Choose the Anker SOLIX F3800 Plus if
- You have, or plan, more than 2,600 W of solar panels.
- You run a 240 V generator and want to pass up to 6,000 W through with Anker's Generator Adapter.
- You want 6,000 W of AC output from a single unit.
Both need a transfer switch or the maker's home panel to feed house circuits. For a lighter backup you can carry, see our home backup list.
