Not the first, wont be the last!

Our most recent purchase was a replacement unit for fhe original used unit we had for 10 years. We did not even hesitate when it came for the replacement. Our first unit was about 5 years old when we got it and it lasted another 10 years and was an absolute blessing when we needed it. So happy we installed a whole home generator shortly after we moved in!

Does the job well!

I have had it for a year now, and of course there has not been a power outage since the installation. However I did decide to run a simulation of an outage and was very happy with the results. My only issue is the description provided on Generac's website, makes it sound like the noise level is just above the level of an air conditioner. If I had an air conditioner that loud, I would be worried!!

Nice product

I purchased this 22 W backup generator about a month and a half ago and hope it works when I really need it. The installation went well and on time however I was not given any instructions on how the generator works or what I should do other than calling them if there's a problem, I was given no information on how to set up the monitoring app on my cell phone at all so I have it on and I guess it's OK but that's about it.

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.

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.

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.

Excellent Great installation, look great Very impressed with the Installers effort to evaluate our power requirements He contacted the local utility company and found out our average and peak power utilization from the past two years and installed a system that will totally support the whole house

26 kW backup generator

Again, my problem is with the electric company that installed it rather than the product itself. But unfortunately, I have not had the support that I would have requested. I.e. asking for a quote for the extended warranty never getting one if Generac can offer that to me now I would be receptive.

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.

I sleep well through storms!!

Had the unit put in June of 24 and have had no issues at all. The sense of security it provides is great.
