Worked flawlessly during each power outage

I bought the 24kw unit with transfer switch from Select Generators in late April 2025. Install went well but had bad oil leak during 3rd hour of the 25 hour break-in period. Dealer and Generac replaced the engine. Since engine replacement the unit has worked great. Only had a few small power outages since install and the generator worked flawlessly to restore home power during each outage. Will see how it does with the 2026 hurricane season. The mobile link is also useful to see hour usage, battery status and history of exercises and outages.

Poor choice on my part.

We purchased it about 2 years ago and it pretty much has failed us when the need arises during storms or other weather in climate conditions. This was bought because I have a cpap machine and need it to sleep. Also to protect the contents of our freezer and fridge.

Quiet enough that I didn't know it was running.

I bought this last year when Michigan was out of power; yes, practically the entire state was out because of a massive ice storm. I was without power for 3 days, called the Genarac dealer and they installed the next day. There was a small problem, they installed the wrong size generator (18KW instead of the 22) but, because it was an emergency, they installed, but didn't bury the lines and set in the ground. They came back after the ice storm and replaced and reset. It runs for 5 minutes every Saturday. Good thing, a year later, another ice storm. Power went out and I didn't even know it. I woke up to everything running, including my robot vacuum. Wasn't till about 1/2 hour later that I realized the generator was running. My only complaint, after about 24 hours, I could smell gas (propane) in my house. I didn't know if it was just the fumes from the generator or if I had a gas leak from ice. But once the generator shut off, the smell went away. So, I guess it was just fumes.

So far, so good!

I have had my generator for about six weeks so far. The installation was quickly and efficiently accomplished. The installation team answered all my questions and explained the operation of the unit. So far, the only experience I have with the unit is when it tests itself every week. I have yet to experience an actual power outage and run on my home on generator power alone.

Well spent money.

Love my new Generac, I feel so much better knowing that I’ll have power during a power outtage. I live alone and it has given me a great security knowing I’ll taken care of. The guys that installed it was fantastic!!! Very VERY professional. I highly recommend GTI Generac power systems.

Best Home Purchase

I have had my generator for 1 year. Love it. Great investment. Peace of mind just knowing that it’s there. I have used it a few times, generator comes on seconds after a power outage. My home functions don’t skip a beat during a storm. Definitely recommend.

Great Features and Reliable

It has been very reliable and we are very happy with our investment and equally happy with Genesis Electric install and assistance! If you've ever been without power for a prolonged period, you know how important it is to have a backup system, and especially important as you age for safety reasons.

New Whole house generator

The generator does what it is suppose to do very well, it's been a savor for a couple storms and power outages. But I have been made aware that the generator should be shut down after prolonged outages intermittently. Which I'm trying to understand what one does when you're away for a prolonged period of time and there is a prolonged outage while you're away?

Reliable during a 4 day power outage

I bought my 22KW wifi enabled unit in April of 2024 along with a service contract from my authorized installer. For the 18 months the unit reliably performed its weekly check run along with providing power during half a dozen power outages that typically lasted from 15 minutes to 2 hours. Many times I didn’t even know the generator turned on and only found out in the monthly email report. Then we had a bad snow storm in March 2026 that knocked out power for nearly 4 days. The generator ran flawlessly. I am very happy we bought this unit.

Dialysis Patient

I am a home dialysis patient, so I need to have electricity to complete my treatments. Whenever the electricity goes out, or even flutters, the Generac automatically kicks on and I never lose power. My only concern was the installer didn't stick around to help me set up the mobile link app on my phone. He had somewhere else to be but said someone would contact me to set it up. It's been a year and still no help with mobile link set up.
