Goal Zero Yeti 500 Refrigerator Runtime Estimate

A compact Goal Zero refrigerator estimate with output and surge limits kept visible. The estimate uses the same runtime engine as the main calculator and keeps source confidence visible.

Goal Zero Yeti 500 portable power station

2h 19m

Estimated runtime for full-size refrigerator.

meets this planning target

2-hour planning target.

AC inverter

Output path with 500 W tracked output limit.

This estimate assumes 500 W running draw, 33% duty cycle, 85% efficiency, and 10% reserve.

Runtime Range

Use the range to plan around temperature, battery condition, and measurement uncertainty.

Assumptions

These are calculation inputs, not lab-tested runtime claims.

  • 499 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.
  • The combined running load is above 80% of the station rating. Leave headroom for heat, altitude, and measurement error.
  • The largest startup surge (2900 W) is above the selected station surge rating (1000 W).

FAQ

Short answers for this model and device pair.

How long will Goal Zero Yeti 500 run full-size refrigerator?

Using the current assumptions, the estimate is 2h 19m. 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.
