after adding all the costs and hassles associated with having a portable standby generator, it is hard to beat the generac home standby power system.
It comes with the transfer switch incorporated in the supplied breaker panel and all the wiring and hardware necessary for installation. If you do it yourself, you would need to buy an automotive battery and a double 40amp breaker for your main panel. Having someone install your LP or NG supply will be the only cost. You could do it yourself if you were not going underground and were able to feed the generator with a 1" supply line. Some of the flex and underground piping in that size is proprietary and would have to be purchased from the utility by a licensed and would have to be approved in underground connections.
I have installed 8 of these generators for relatives and friends and I am pleased with the quality of these units. Duplicating a standby panel for someone who has a gasoline powered standby generator is expensive and the pits IMHO
