Generac is pretty low-end. IMO, what you get depends more on the outage you foresee. Do you want something that will run your whole house for a week or two whilst Texas gets its act together? A couple of days while the local utility finds the problem and fixes it? Do you foresee some event that lasts for a year? If the former two, Generac is fine. For some long-term deal, you're gonna need a CAT diesel or the like. Two problems with Generac or similar brands...one is longevity. I don't think ANY gasoline, propane or natural gas system is going to be long-lived. Second problem is cost to run it...just fuel. Diesel is gonna cost a lot less over the long run. I expect there are a lot of people who could withstand the $10k to $20k expense of a full-featured, whole house genset, who couldn't afford to run it for a year.
JMO and I'm no expert.
