I purchased a Yamaha 2400 iSHC with propane conversion kit for my business. I have a telecommunications business and this inverter generator is perfect for sensitive electronic equipment like computers while having the ability to run a large freezer and large refrigerator. With this set up, I have the ability to use gas, propane and natural gas. The unit is quiet and easy to maintain. I loved it so much that I just purchased a Yamaha 3000iSBE two weeks ago.
Just in case anyone is interested, I purchased it here locally from World-Wide Industrial. The guy is certified by Yamaha to install the propane conversion kit. It does not affect the warranty. They deliver to your door, walks you through starting the generator with the propane kit (he brings a tank of propane with him), and shows you how to maintain the unit.
The owners name is David, really nice guy and Carol works in the office. Its a mom and pops local business. Great customer service.
http://aaaworldwideind.comIn a SHTF situation, gas may not be available but if you have a gas grill, you can always hook your propane tank to your generator. I keep three propane tanks full at all times. Its a lot more stable to than keeping gas in a can. If you do you gas, you want to use Ethanol FREE gas in your generator. Ethanol gas ruins your seals and gunks up the lines. Propane is easier on the generator than gas. It will run cleaner.
Just wanted to add my 2 cents in hopes it would help someone. I did months of research before I chose a try-fuel generator. Good luck with whatever you choose.
