You need to speak to a electrician or electrical engineer. There is much more than just buying the generator if you plan on running the entire house on it. You'll need a transfer switch which "transfers" from the perminate power source to your gen unit. You'll also need another electrical panel and conduit. The panel and switch can cost you more than the gen unit. All this takes up room so plan on giving up part of your garage walls and floor space.

Not saying it can't be done but you need talk to a pro.
