Quoted: I have one. runs on propane and I have a 500 gal tank of it. Mine is Kohler. It's awesome. it runs all the important appliances and circuits in the house. Power flickers, generator automatically comes on. Highly recommended. |
Ditto on the Kohler, and unfortunately I've not heard good things about the durability or reliability of the Generacs. Kohler, Onan, and Caterpillar are really the big commercial generator manufactuters... most of the rest are second-tier.
And I don't know how much Diesel fuel some of you are planning on storing... but that's a major PITA. At around a gallon an hour, you're going through five jerry cans per day. Diesel does store better than gasoline, but it still must be rotated out... and unless you're steadily using it up and replacing it (running it through your power-stroke Diesel dually or something), you're going to run into storage problems.
In contrast, getting a propane tank buried in your yard is quite doable. Get a large enough tank and you've got enough fuel to run a good-sized generator 24/7 for several weeks... plenty of time to get somebody in there to refill your tank. You can also use that propane to power your furnace, heat your water, and run your cooktop in the kitchen. Yes, you'll use a little more Propane to power your generator compared to other fuels, but the storage is much easier (Propane and NG have a lower energy content than liquid fuels like Gasoline or Diesel, and require proportionally more fuel to power the genset).
Just be aware of some of the issues with buried tanks, including water table, and corrosion.
