How long could it run?

Enter your total average load. Change the efficiency assumption to explore the effect of energy losses.

Use the estimate well

Use average power over the period you want to cover. Devices that cycle on and off require a measured or credible average. The usable energy assumption is illustrative and is not measured efficiency for these models.

This calculation does not test compatibility, startup surges or simultaneous output limits. Inverter idle consumption, battery condition, settings and temperature can change actual runtime.
