Planning default · ≤ 18h 59m

AC inverter

Continuous output rating (W): 4,000 W

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.

  • Battery capacity (Wh): 4,096 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
