Buying guide: how to choose the right home backup power station

Portable station or home battery?

These units are 26–82 kg. Most have wheels, but think of them as a battery you park near your panel, not something you carry to a campsite.

Connecting to your house

To power hardwired circuits you need a transfer switch or the maker's smart home panel, installed by a licensed electrician. Never backfeed a house through a dryer outlet.

240 V matters for wells and dryers

Well pumps, electric dryers and some HVAC need 240 V. The DELTA Pro 3, DELTA Pro Ultra, Explorer 5000 Plus and F3800 Plus list 120/240 V on the unit.

Solar sizing

A 3–6 kWh battery needs 1,500 W or more of panels to refill in a day. Check the station's high-voltage PV range before buying rigid roof panels.

How this ranking is calculated

Score = weighted average of normalised specs, out of 10. Full method

Battery capacityUsable runtime scales with watt-hours. A 1,000 Wh station runs a 100 W load for roughly 8–9 hours once inverter losses are counted. Scale: 3000 → 6200 Wh.
25%
Continuous AC outputThe rated (continuous) inverter output decides which appliances you can plug in. We use the rated figure, not surge or 'boost' modes. Scale: 3000 → 7200 W.
20%
Max solar inputHigher solar input means faster recharging off-grid, if you have enough panels to use it. Scale: 1000 → 5600 W.
15%
WeightLighter is easier to carry to a campsite or between rooms. Scale: 90 → 25 kg.
10%
Max AC charging powerMore AC input watts means a faster wall recharge before a trip or storm. Scale: 1500 → 3000 W.
5%
240 V output (listed)240 V output runs well pumps, dryers and other 240 V circuits through a transfer switch or home panel. We mark Yes only when the maker lists 240 V output on the unit itself.
10%
Rated cycle lifeHow many full cycles the maker rates the battery for. Thresholds differ (70% vs 80% remaining capacity), so read the note under each product. Scale: 2500 → 6000 cycles.
10%
Surge / peak outputShort bursts for motor start-up (fridges, pumps). Skipped when the maker doesn't publish a surge figure. Scale: 6000 → 14400 W.
5%

Frequently asked questions

How long will 5 kWh run my house?

It depends on what you back up. Essentials such as a fridge, internet, lights and a furnace fan might use 3–6 kWh a day; central AC and electric heat use far more.

Do these qualify for the federal battery tax credit?

EcoFlow notes that battery storage of 3 kWh or more must be installed and connected to a home to qualify under Section 25D. Ask a tax professional; we don't give tax advice.

Can I add a gas generator?

Several models list generator charging or pass-through, including the Anker SOLIX F3000 and F3800 Plus and the EcoFlow DELTA Pro 3.
