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.

Full-size refrigerator: 500 W · Duty cycle (%): 33% · Efficiency (%): 85% · Reserve kept unused (%): 10%. Runtime is conditional on successful startup, compatible voltage/connectors and sufficient output. Verify the actual device setup before relying on these hours.

Runtime range

These are calculated sensitivity cases, not a statistical confidence interval. Conservative uses lower efficiency and battery health, more reserve/temperature loss and higher load; optimistic changes these assumptions in the opposite direction.

Assumptions

Use this as a planning estimate, not a guaranteed runtime claim.

  • Battery capacity (Wh): 768 Wh
  • Device wattage (W): 500 W
  • Duty cycle (%): 33%
  • Output path: AC inverter
  • Efficiency (%): 85%
  • Reserve kept unused (%): 10%
  • Battery health (%): 100%
  • Cold weather loss (%): 0%
  • Device startup surge (W): 2,900 W
  • Fixed station overhead unknown; not included
  • This is an estimate. Real runtime changes with load, temperature, battery age, AC/DC output, and device behavior. Runtime is conditional on successful startup, compatible voltage/connectors and sufficient output. Verify the actual device setup before relying on these hours.
