Have commissioned this unit for about a week. Running on both Propane and no-Ethanol gasoline. Works just as expected. Ran my deep-submersible well pump fine. Only criticism: the included manual has items which are not correct with my unit. Seems you have to download a better manual....this should be stated therein.
This generator is large enough to power my entire house. It has the advantage of being dual fuel. I use it almost exclusively on propane but in a pinch, I can run it on gasoline. It runs relatively quiet, and I barely hear it humming away outside.
Waited over a year to evaluate the 9500 DF. I use it for home back-up power. I have installed the Westinghouse ST Switch for a complete back-up power system. System performs perfectly.
