Every setup and its answer

Runtimes are hours of each setup's daily routine, with use spread through the day, at 85% efficiency. The closest fit is the smallest capacity that is enough; a tie goes to the lower price, then the lighter unit. The methodology states every formula.

Your own setup

Every setup page has a link that opens its list in the calculator, where you can change any appliance, its watts, its hours and the goal. To start from your own list, open the runtime calculator.
