16h 41m

Estimated runtime for full-size refrigerator.

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.

Runtime Range

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
  • This is an estimate. Real runtime changes with load, temperature, battery age, AC/DC output, and device behavior.

Sources

Station facts and scenario wattage notes stay separated so the estimate is easier to audit.

Confidence

  • Station: verified
  • Scenario: estimated
  • Last station verification: 2026-06-24

Next Steps

Refine this estimate if your actual device wattage or power path is different.

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.
