Refrigerator backup means surge matters more than capacity — compressors hit 600 to 800 W on startup. We weight surge, then capacity, then cycle rating.

Avoid if: Don't have the budget for a large home-backup system
We filtered the database for surge handling >= 800 W and ranked by the home-backup sub-score and capacity. Refrigerators need duty-cycle-aware runtime calculations.
Surge rating, usable capacity, cycle rating for repeated compressor cycling, and warranty.
Best for: Whole-home essentials unit with strong 3600W output and EV-grade charging
Avoid if: Better warranty tier priced lower elsewhere (Bluetti AC300, Anker F3800)
Best for: Whole-home essentials inverter-splits with up to 2400W solar and stackable batteries

Best for: Featherweight 8.3 lb camping unit with solid USB-C PD
Avoid if: You need real appliance runtime
Best for: Bluetti's budget 268Wh LFP camping unit — small stash for weekend daypower
Avoid if: You need app support or >600W surge budget
Six to seven hours assuming a 40% compressor duty cycle and 150 W average draw. The Delta 3 Plus and Anker SOLIX C1000 both get you there.
Most fridges pull 600 to 800 W for the first second at compressor startup. If your power station's surge rating is below that, the unit simply won't start.
