Consumption figures are manufacturer-reported values, exactly as published by the source below; propane figures for some brands are published in cubic feet per hour with the gallon-per-hour equivalent in parentheses. A figure shown as “Not in our database yet” means the source does not publish a comparable value. We leave it blank rather than estimate it.
How its price stacks up
At $20,149 for 30 kW on propane, this model works out to about $672 per kW. The median standby in our database is about $358 per kW (propane rating), so this one prices about 88% above the class median.
That is the generator alone, before installation. Standby installs add a transfer switch, pad, gas and electrical work, and permits; the cost guide breaks those down. Prices move; treat the figure as a compiled street price from October 2026, not a quote.
Will it run your house?
On propane, this model is rated at 30 kW continuous. Whether that is enough depends on what has to start at the same time: a well pump or central air conditioner can draw several times its running watts for a few seconds. Run your own appliance list through the sizing calculator, then see this model highlighted against your number in the model database: highlighted rows clear your requirement with the calculator’s 20% headroom included.
