Home backup power

When a small power station is not enough. Here are the bigger systems that can run 240 V loads and stretch to tens of kilowatt-hours, compared on what their makers publish.

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.

Two kinds of larger backup

Expandable whole-home power stations sit on wheels, plug into a home panel or transfer switch, and add battery packs as you need them. You buy them from the brand and can move them.
Professionally installed home batteries mount on a wall or pad, connect through a gateway or controller, and are sold through installers. The brands below do not publish a consumer price, so you need a quote.

Either way, connecting backup power to your home wiring is a job for a licensed electrician and your local permit office.

Smaller needs?

If you need less than about 3 kWh and no 240 V, a regular power station is usually enough. Try the power station selector or the runtime calculator. For installed systems, see can a power station back up your house? and the home backup calculator.

Frequently asked questions

What counts as whole-home backup?

A system that connects to your home's panel through a transfer switch, smart panel or gateway, with enough output to run the circuits you choose. The power stations here list 120/240 V output, which is needed for loads like well pumps and central air.

Is an expandable power station cheaper than an installed battery?

The power stations here list prices starting at $2,799 (EcoFlow DELTA Pro 3, Nov 3, 2026) before any panel, switch or installation. Tesla, Enphase and FranklinWH do not publish consumer prices, so compare real installer quotes.

Why is BLUETTI missing?

BLUETTI's site rate-limited our requests when we checked, so we could not read its specs. We will add the AC500, EP900 and Apex 300 once we can verify them on BLUETTI's own pages.

Did you test these systems?

No. We have not tested these products. Everything here comes from manufacturer pages and datasheets.
