Catalog sump pump is 500W. A sump runs in bursts when the pit fills. Hours below are at 500W continuous.
Hours use usable watt-hours: nameplate Wh x 0.80 depth of discharge x 0.90 inverter efficiency. The 1.25 sizing buffer is for buying a new battery. It is not used for hours of a station you already own.
Catalog default is 4 hours. Storm duty can be more. Size the battery for the wet hours, not a dry basement.
Only power stations Field Authority has signed appear here. Catalog SKUs without a lock-file row stay off this table.
Compressor start can exceed nameplate. This table uses continuous watts only. No unsigned surge number.

Usable watt-hours are 3072 x 0.80 x 0.90. At 500W that is 4.4 hours of pump-on time.
If continuous inverter watts are at least 500W, it clears the gate. A 300W inverter cannot. Hours on a small battery are short in a long rain.
If the pit fills when the grid is down, yes. This table is hours at 500W, not a promise the pit stays dry.
