Customer review of Cummins QuietConnect 25kW home standby generator.

Here’s what some of our customers had to say…

  • ★★★★★
    A storm with high winds, recorded as the third worst in Memphis history, left over 180,000 customers without power for days, some over two weeks. My Cummins started up as soon as the power outage began and ran for 36 hours straight. I'd never been happier with my purchase. No worries, no fuss, no problems. Thanks, Cummins.

    As the former owner of an industrial company, I’ve used Cummins engines and generators professionally, so when I went to buy a generator for my home, I knew I wanted a Cummins.

    Excellent generator, excellent installation. I would highly recommend this unit to anyone looking for a top-notch generator. Cummins is the only way to go!!!

    Our generator got it's first real workout three days ago when a storm rolled through our area. We lost power for the first time since we built the house. The generator kicked on within about three seconds with no hesitation. Our entire family felt great comfort that we had power back up and running instantly. We love the generator and the peace of mind it provides for our safety and the protection of our largest investment....our home.

    The reason I selected Cummins (over Kohler or Generac) was the aluminum enclosure, quiet design, free online monitoring, remote panel (that shows load), and of course had to be Made in USA.

    Very pleased with the equipment and the service provided by the local representatives.

  • ★★★★★
    I am a fan of Cummins quality and insisted on a Cummins for my standby generator.  Have not lost power yet (that's a good thing) to see it in action, but I expect nothing less than complete satisfaction.

  • ★★★★★
    We have only needed it a few times. It was worth the investment when we did have a need. I have asthma so it really is a lifesaver.

  • ★★★★★
    I cannot express my deep appreciation to you folks at Cummins for the design/engineering/manufacturing of this excellent product. Here in the northern NM mountains, our home is subject to periodic electrical outages, and the generator has repeatedly and reliably kept our home fully electrified.

  • ★★★★½
    The quality is way above the competition. The big box store generators are marketed really well and overrated. They put a lot of advertising dollars behind their products and put less into the quality control of their generators. If you want quality and longevity, buy a Cummins. You get what you pay for, and if you want reliability, there is no other choice. Very satisfied.

    I looked at other home standby generators, but already knew which one I wanted – a Cummins. I like the feature that allows me to start the generator to test the transfer switch. I would highly recommend a Cummins generator.
