Capacity (Wh)
Higher capacity means longer runtime between charges. For whole-home backup, we recommend at least 3,000Wh.
Whole-Home Backup
Best Power Stations for Whole-Home Backup
Power your home essential circuits during extended outages
Whole-home backup means running your furnace, well pump, refrigerator, and lights at once, often through 240V split-phase circuits. You need 3,000Wh or more of expandable LiFePO4 capacity and high continuous output to bridge multi-day grid outages.

What to Look For
Before comparing specific products, here are the key specs and features that matter most for whole-home backup.
Output Power (W)
Determines what appliances you can run simultaneously. Check that the continuous wattage exceeds your largest load, and verify the surge rating handles motor startups.
Expandability
Can you add extra battery packs later? Expandable systems let you grow capacity without replacing the entire unit. Critical for growing off-grid setups or changing needs.
Max Expanded Capacity
Check the maximum total capacity when expansion batteries are added. Systems that expand to 10kWh+ can serve as semi-permanent cabin or home backup power.
