What the numbers mean
- At 26,000 running watts on its best fuel, this unit is sized for whole-house coverage on a typical 200 A home, subject to a load calculation by a licensed electrician.
- Runs on natural gas, propane — expect lower output on propane (roughly 10%) and natural gas (roughly 20%) than on gasoline; the spec table shows the published per-fuel ratings.
- Estimated fuel cost for 24 h at ~50% load: about $65 on natural gas at national average prices (assumptions).
- Permanently installed unit: sizing, gas-line capacity, placement clearances, and the transfer switch are a job for licensed installers under local permits.
