Clark, is that you???
Just installed a 22kw generac that will run everything in the whole house. Expensive, but worth it to me.
The question is more along the lines of, what is the purpose of the generator? Temporary power or long-term whole house power? For a day or so, a portable one is more affordable. My neighbor has a Gentech whole-house unit, had to just have it completely redone, new tank installed. Has to run monthly just to keep functioning, very costly.
