We design standby generators specifically for extended run times, so having it run for a week or longer is definitely possible. Your only limitation is the fuel type, meaning the size of your propane tank or the supply of natural gas. For natural gas at ½ load, the 20kW uses 206 cubic feet per hour. For liquid propane at ½ load, the 20kW uses 1.89 gallons per hour. Refer to the 20kW spec sheet for additional fuel consumption data. http://www.generac.com/SpecSheets/0...
We also recommend stopping the unit and checking the oil after 24 hours of straight operation and performing scheduled maintenance after 200 hours of operation.
