that richard gray piece is sick, and very expensive i might add. i just priced a 15kw generac, installed and i believe it was $6,000 maybe $8,000. i cant remember and we moved from that house so we did not pull the trigger on it. in reference to $30,000 for 11kw, wow.

as far as why you would want entire house on generator, why not, if you got $$ why wouldnt you want absolutely no interuption in your life due to things you cant control?
