24KW in Ohio

Everything works as planned. My install was April 2025 and I just had an event in March 2026 where the unit ran for 24 hours consecutively. No issues. And very little oil usage. My recommended installer is 5*.

Happy with my 24Kw.

I have had Generac 24W for 1 month and it's weekly start and programed runtime has been good. Power has one out for about 5 minutes and Generac started and powered of when power back on.

Successful Generac Generator Purchase

Rob LaMaster, the Generac dealer from whom we purchased our Generac Generator, was simply terrific in all aspects of of his pursuit to provide us with this product, and guided us with care and knowledge. Rich Sternberg

Peace of mind

We bought it last month and hope we never have to use it for emergencies. My wife is on oxygen and needs it almost 100% of the time. We bought it so her oxygen machine would still work if we had a power outage.

No more worries

Within 6 months of installation we had a 2 day power out event, so the peace of mind was worth it, since it was at our 2nd home and we were not there.

Reliable stanby generator

I bought this uint from Sam's club and had it installed by my electrician. I was not aware that the unit did not come with a battery. Overall, I would buy this unit again.

Generac - Good long term investment

I bought my second Generac for a new house one year ago. As the one at my previous residence, it works as advertised. No problems. Weekly testing performed. I would highly recommend this product.

Solid Unit

I have had my unit installed for 731 days. Through 2 power outages it performed well. The first one lasted for several days; shutting it down to rest and change the oil was easy. Being able to monitor the unit with the mobile App is a great feature.

Right on time!

My 18KW Generac standby generator is one of the best investments that I have ever made for my home. The unit supplies all of the emergency power needs to my home during a power outage, which occurs frequently in my neighborhood.
