how many watts generator
A smaller 3,250-watt portable model might set you back about $300 to $400, while a 10,000-watt model might go for about $1,200. If you want the whole shebang -- the whole house generator -- a 20,000-watt model will cost you about $5,000 at Home Depot. Still other generators go for as much as $10,000. Installation, of course, can also be costly. For a look at how to install your own whole house generator, check out this video.
