I am looking for back up power generator. Any suggestions?
Hello There are different kinds of power generatorswhat purpose are you looking to fulfill? How big is your home or wherever you're trying to heat? I would recommend a diesel generator as opposed to a gasoline generator. They're more efficient, which also translates to being much cheaper to run. They make silent diesel generators (not 100% silent but decently quiet). If you wanted to do some welding with the generator, you could do that too. This site has several kinds of generators listed gtpower.ca
For used medium size portable temporary units about $100 to $150 US per KW. Plus the required transfer switch and permits and inspections if you intend to power your house with it. This is for a manual start gasoline powered unit. As you add options the price goes up and may triple in hurricane season in the path of the storm. The quietest unit I've found are Honda, but they are more expensive. Any unit smaller than 15KW should be considered a short term unit good for maybe 2000 hours of run time. A 15 KW unit should be a permanent installation with a mounting pad and at least a 7 day supply of fuel on site. For this a licensed qualified professional electrical contractor should be consulted. As convenient as they may be, they can get to be expensive to install and operate.
