  1. Definately Worth the Extra Money

    Posted by Carl P. on 12th Nov 2014

    I've installed other brand units for people I know and was never very impressed with the quality of them, especially the Generac's. My wife and I are building a new house out in the middle of farm country and did a lot of research before ordering one. When it arrived on the truck, the first thing I was impressed with was how well it was crated up. Even the delivery guy couldn't believe all the 1x4's and how stout the crate was. Once it was unpacked and I started to look the unit over, I was very impressed with how well it was made. I am an engineer by trade and everything was well thought out from the cabinetry, the intake/exhaust through the top of the hood, the serviceability, the quality of the materials, the transfer switch, etc. The installation instructions are a little to be desired for the do it yourselfer, but it was probably one of the cleanest installs I've done. The unit is so quiet, I can't even hear it running unless I open a window and stick my head outside. Switchover is seamless and the power generation is superb without any flickering as loads are applied.


  2. 20kw Cummins Onan Is Worth The Money

    Posted by John M. on 10th Aug 2014

    I purchased after lots of research. I was tired of dragging out the portable one from the garage. I chose this one for the ability to turn it on and off from inside the house and that I was able to find a Cummins rep to repair it if needed. I am very happy with it, it was not hard to do some of the install myself, I dug the line and set the electrical pipes in place. I even pulled the wire through. I had an electrician do the final hook up and a gas company do the final connection to LP. They were both surprised how quite this generator is compared to others, it sounds as quite as an air conditioner. In 9 months it has come on a couple of times with no issues, I didn't even know it turned on. I would recommend you check over the generator very carefully for damage even if it is in clear packaging. Mine had a crack in the top from the delivery team i did not see, the good news is UPS made good on this and gave me the money for a new top. You get what you pay for with this generator, easy to use and easy to access the inside for routine maintenance, the communication cables that it came with were very convenient. I am very happy.


  3. Absolutely the Best

    Posted by Tony on 21st Oct 2012

    When I researched the purchase of a home standby generator, I was concerned about three things. Efficiency, sound level and warranty. The Cummins Onan unit excelled in all three catagories, The price is a bit more than the competition, but the advantages are huge. The installers could not believe how quite it is and how quickly it starts and provides electricity. The Onan se switch is made with high level components - not usual with the competition. The indoor monitoring control is simple and easy to use. The low sound level is astonishing - my neighbors Generac across the street drowns out my unit when when they are both exercising. I would gladly do a free commercial for Cummins Onan for this unit.
