I upgraded my Generac Guardian generator from 15KW version to a 22KW version (due to load increases). I have to say I am pleasantly surprised on the quality of power being delivered. The old generator fluctuated several hz (+-2 Hz) and had a hard time holding a steady voltage. We are using this generator to power a small data center, power quality is important as UPS don't like dirty power. This new generator holds voltage steady, the frequency is within +-0.1 Hz. Even when the large roof top air conditioning unit kicked in, the generator powered up and recovered the correct voltage and frequency within a second. The power monitoring is also a nice touch. Now I know when we loose power and if the generator kicked in or not. Although the old unit mechanically was working fine, visually the case was metal and rusted heavily. This new case is aluminum so we are expecting no rust.

I used to worry every time it rained hard. No more! This is the best investment that I have ever made. It tests itself once a week, so it is always ready. I haven't had it long, but twice the power has gone off, and it came right on. I love it and do not why I didn't buy this years ago.

Our Generac was installed and ready to go before a hurricane hit our city. Thankfully, we had it just in time as we were without electricity for 5 days. Needless to say, our Generac did not miss a beat, went on flawlessly when we lost electricity and off when it went back on. We would recommend a Generac to anyone who has experienced being without electricity, for whatever reason, or for any length of time.

So far, so good. We have had a couple of short term outages and everything worked as expected. Hopefully we will never have to use it for an extended time but it is comforting to know it is there. We are a retired farm couple who decided to stay in our older home in the country rather than move to town. A little pricy, but definitely worth the piece of mind it provides.

I kept waiting for a power outage to see if the unit would cycle as it should and it performed perfectly when the outage happened. The unit is the required distance from the house and is barely noticeable when running. BTW: The installation was done by people that knew what they were doing in a very professional manner.

In the past I have only installed water cooled units at our homes but I decided to try the 22KW or this installation. The area required is much smaller but the unit seems to be as noisy as a 3600 RPM water cooled unit. I am not sure what i expected but I was surprised at the level of noise the first real power loss.

I just purchased a 22kw generator by generac happy with it so far haven't had a chance for for it to kick on but at installation time it ran very well looks good I like the price very happy with it I would recommend it to any one wanting a home standby generator

We've had the unit a couple of months and it has performed as advertised, we had a couple of power outages of 1 to 2 hrs each and the unit came on and switched to backup power without a hitch. A nice feature is the generator has a self test mode running once a week for 5 min so you know your generators ready to go in case of power outage. Would recommend to all.

This generator was purchased for a home in Belize and the sales and installation team were awesome. I have not had to use the generator but I have complete faith in the product and the installation. Was only disappointed the free Genarac pressure washer deal was not available in Belize. Thank you for a great product and a great team

Installed April 2017 right next to service entrance. Looks very nice and reassuring. My wife and I feel a weight lifted. No more 20 below January nights yanking on a pull-cord with stiff oil in the pan. First power outage came this June, in 45 seconds we had power and there was no hint when the power came back and the generator turned off. We have the 22kw standalone. One thing to remember. The generator comes set for a delay start up time of only 5 seconds. Every little power hit or sag will have the generator starting and stopping. Only your approved service installer can change that time. We had ours changed to 30 seconds. No only real power failures turn the generator on. Comes on every Saturday morning for 10 minutes. Connected to its own 500 gallon propane tank. Worth every cent at 73 years old. Save a lot of money the closer to your service entrance you can get. Buy the biggest generator you can afford, I suggest the biggest.
