EcoFlow DELTA Pro Refrigerator Runtime Estimate
A full-day refrigerator planning estimate for the EcoFlow DELTA Pro with compressor surge and reserve visible. The estimate uses the same runtime engine as the main calculator and keeps source confidence visible.
does not meet this planning target without changing load, reserve, or capacity
24-hour planning target.
AC inverter
Output path with 3600 W tracked output limit.
This estimate assumes 500 W running draw, 33% duty cycle, 85% efficiency, and 10% reserve.

Assumptions
These are calculation inputs, not lab-tested runtime claims.
- 3600 Wh nominal battery capacity
- AC inverter output path
- 85% conversion efficiency
- 10% reserve kept unused
- 165 W average load from 1 load
- 100% battery health
- 0% temperature loss
- Fixed station overhead unknown; not included
- This is an estimate. Real runtime changes with load, temperature, battery age, AC/DC output, and device behavior.

FAQ
Short answers for this model and device pair.
How long will EcoFlow DELTA Pro run full-size refrigerator?
Using the current assumptions, the estimate is 16h 41m. Real runtime depends on device settings, output path, temperature, battery age, and measured wattage.
Is this a guaranteed runtime?
No. It is a planning estimate from source-linked station specs and scenario wattage assumptions. Use a watt meter and manufacturer guidance for critical backup planning.
