This is a photo of a 20kw Generator which we installed. We installed a 200amp automatic transfer switch which converts line power to standby power when power loss is detected. That makes this hands free for the home owner. The unit runs on propane or natural gas which makes this even more attractive to those who dread filling gas cans. We also install smaller units for those who want to specify only what is most important. These units can be from portable gas units to small standby units that run on natural gas or propane.
Pricing these units varies depending on size and location of the unit.
