About this category

Backup power sizing should start with what you actually want running during an outage — not with your square footage. These guides work from loads back to capacity.

BLUETTI and EcoFlow are two separate shopping paths rather than a ranking. Battery backup systems are portable or expandable units, not permanently installed whole-house standby generators. What a system can actually run depends on the model you choose, its usable battery capacity, its continuous and surge output, the loads you connect to it, and how it is installed. Guidance on permanently installed standby generators stays in the standby generator guides.
