Anker SOLIX C800 Refrigerator Runtime Estimate
A refrigerator outage estimate for the C800 where capacity, reserve, and compressor cycling are 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
4-hour planning target.
AC inverter
Output path with 1200 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.
- 768 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 largest startup surge (2900 W) is above the selected station surge rating (1600 W).

FAQ
Short answers for this model and device pair.
How long will Anker SOLIX C800 run full-size refrigerator?
Using the current assumptions, the estimate is 3h 34m. 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.
