Good timing on this thread as I am looking at backup power for my home and just installed a security system for when the power goes out and there is a potential for unwanted intruders in the neighborhood. I originally looked at battery power but have come to the conclusion that it is not enough. I have also come to the conclusion that a whole house generator is what I need even though we currently rarely loose power. I think that power outages will become more common in the future and with power out vulnerability increases in this day and age. Currently looking at Generac and Kohler. My brother has 2 Kohlers and I am leaning that way even though they are a little more expensive and I see many horror stories on line about the Generacs.
