Power Station Runtime Matrix
Enter one appliance profile and compare estimated runtime across the entire source-linked model set.
Estimated runtime by model
| Model | Capacity | AC output | Estimated runtime |
|---|
Choose the duty cycle carefully
A 150W refrigerator does not normally consume 150W for 24 straight hours. If its compressor runs one third of the time, a 33% duty cycle creates an average effective load near 50W. Pumps, freezers and furnaces also cycle, but their duty changes with weather and workload. Use a plug-in meter or actual run-time observation whenever possible instead of treating the presets as measurements.
How efficiency and reserve change the answer
AC conversion consumes some battery energy, and planning to reach 0% at the exact end of an outage leaves no margin for colder weather, battery aging or an extra appliance cycle. The default 85% efficiency and 10% reserve are transparent planning assumptions applied equally to every model; they are not claims about any specific unit’s tested performance.
Why a matrix is more useful than one runtime number
The matrix keeps the appliance assumption fixed and changes only the power station. That makes the capacity difference visible without changing the formula. Use it to narrow a capacity class, then use the comparison tool for a more complete two-model decision.
Power limits still matter
Continuous inverter output must exceed the appliance load, and motors or compressors can require additional startup surge. This runtime calculation answers the energy-duration question only; it does not certify that a particular inverter will start or safely power the appliance.
