5,000 Watt+ Power Stations & Home Backup

A 5,000 watt or larger system can run a home's essential circuits, but usually not every large appliance at the same time. A 7,200W system covers a refrigerator, freezer, lights, Wi-Fi, a well pump and a washer together. Adding an electric water heater (about 5,000W) or a dryer (about 3,400W) uses up much of that output. The EcoFlow DELTA Pro Ultra X (12,000W) and the Anker SOLIX E10 with its Turbo Output give more headroom.

Yes, a system with 240V output can run a typical 1 HP, 240V well pump, which draws about 1,500W running and up to about 4,500W for a moment when it starts. The Jackery Explorer 5000 Plus, Pecron F5000LFP, EcoFlow DELTA Pro Ultra, EcoFlow TITAN 5000, BLUETTI EP800 and Anker SOLIX E10 all supply 240V. A pump that runs about an hour a day uses about 1,500Wh, roughly a third of the usable energy in a 5kWh battery.

Yes, a 240V system rated well above 4,000W can run a typical electric dryer, which draws about 3,400W running and about 4,000W at start-up. It uses a lot of energy, though. One hour of drying takes about 3,400Wh, so a 5,040Wh system delivers enough for a little over an hour. Save the dryer for when you can recharge from solar or the grid, and use the battery for essentials first.

The BLUETTI AC500 is a 5,000W inverter with no built-in battery, so you build the system around B300K expansion batteries. Our listing offers it alone or with one to six B300K batteries, from about 2,765Wh to 16,588Wh. With two or more batteries it delivers its full 5,000W continuous output and 10,000W surge, and with one battery its output is limited to 3,000W. Each AC500 supplies 120V, and two units linked through a P030A Fusion Box provide 240V split-phase power. It appears in this output collection but not in a capacity collection.

Split-phase power is the 120V/240V service that U.S. homes typically use, with two 120V legs that combine to make 240V. Standard outlets use one leg at 120V, while large appliances such as well pumps, dryers, ranges and central air use both legs at 240V. A home backup system with split-phase output can feed both legs of your panel through a transfer switch or home panel, so 240V and 120V circuits both work during an outage.
