Best home backup power station for outages
Picks based on what each maker publishes: storage, output, 240 V, solar input and price. Not on testing.
We have not tested these products. Specs and prices come from each manufacturer’s own product page or datasheet, read on Nov 3, 2026. BLUETTI models (AC500, EP900, Apex 300) are left out for now because BLUETTI’s site rate-limited our requests, and we do not list specs we could not read.

How to choose
- Size your storage with how much battery do I need?
- Check you need 240 V. All five models here list 120/240 V output.
- Decide how it connects: a smart panel switches over automatically; a manual transfer switch means you flip it yourself.
- Count the extras: battery packs, the panel or switch, and an electrician add to the price.

Frequently asked questions
What is the best home backup power station?
It depends on your load. On listed specs, the EcoFlow DELTA Pro 3 is the cheapest 240 V entry here ($2,799, Nov 3, 2026), and the EcoFlow DELTA Pro Ultra and Anker SOLIX E10 list the largest systems (up to 90 kWh).
Can a power station run my whole house?
Several of these list 120/240 V output and whole-home panel options, but output limits what runs at once. Check continuous and surge ratings against your loads.
Did you test them?
No. We have not tested these products. The picks use manufacturer specs and prices.
