Curious as to what you consider a fortune for a generator?... My pops has one that he spent like 5-6k on that will power and entire floor of a house... weve only had to use it once for the house but would you consider that dirty power? I'm assuming your talkin about a smaller generator that doesnt have as much kick, this ones pretty big.

Has anyone thought about a battery back up? I got one that is made for backing up a computer server and my thermostat runs through that... Its made to last like 3-4 hrs running a server at Max so I've been told it should last 3-4 days with the small output I have using just flexwatt. I've been lucky and havent had to use it but its there if I do.
