Full catalog
Cummins home standby generators
All 35 models we carry, with published pricing from $4,286.47 on 26 of them. Prices shown are for the equipment only. Open-set diesel and units above 100kW are quoted per project rather than listed, because they are specified against your service and switchgear. Installation is quoted separately after a free on-site survey — here is what that typically adds in DFW.
Air-cooled — 13kW to 20kW
Natural gas or LP, aluminum enclosure, residential footprint. This is what goes in almost every DFW backyard. Air-cooled tops out around 20kW because beyond that an air-cooled engine cannot shed heat over a multi-day run.
