What size generator runs a freezer?

Use the about 2,200 W inverter class as the starting estimate for Chest freezer.

Running 500 W + largest start delta 1,000 W = 1,500 W peak. Add 25% headroom: 1,875 W.

Sizing estimate only - confirm with a licensed electrician; never backfeed a panel.

Why the estimate can change

Use nameplate watts when available. Pumps, compressors, altitude, fuel type, and extension-cord voltage drop can all change the practical generator size.
