Battery runtime calculator

Watt-hours in, hours out. It is arithmetic, not a measurement. Real runtimes depend on temperature, battery age, and how the load changes.

The formula

hours ≈ (watt-hours × usable share × efficiency) ÷ (watts − solar watts)

The loss figures are typical planning assumptions, not measurements of any product. Check your power station’s manual for its real efficiency, and measure your gear’s draw with a watt meter if you can.

Solar panels rarely deliver their rated watts. Enter what you really see on the power station’s display.
