On a full charge, with no other loads. A sump pump uses 0.2–1.5 kWh a day and draws 300–800 W while pumping (⅓–½ hp); about 85% of the battery reaches the outlet after the inverter's losses. Needs power most during storms, exactly when the grid tends to fail.
Tip: Check its startup surge against your power station's rating.
