Runtime uses each load's duty-weighted average draw against 90% of the rated capacity — conservative on purpose. Cyclic loads (fridges, pumps) run far longer than running-watts × capacity would suggest.

On its own, the Explorer 100 Plus is better suited to single appliances and lighter loads than the full multi-appliance scenarios we track — see what it runs above, or step up to a larger unit on the all-units page.
