We had our unit installed several weeks ago and had a local failure of someone hitting a trnasmission pole. The unit went on immediately and ran continuously until service was restored. I was very impressed in that not even our automatic light timers were affected.

In 2006 I bought my first backup generator. It was a 22kW liquid cooled and worked flawlessly. My new one is a 22kW air cooled and is awesome as well. At my old house, I plumbed it to my gas line, this one is on propane which it sips. The notifications to my phone give peace of mind. Great, great product. Beautiful. All other generators are losers.

I purchased the first unit for our home and a second unit for our cottage, about a month later. The units are performing great, they are currently set to cycle on for 5 minutes once per week. Had one very short power loss at our house and the generator did its job. It started within seconds of the power loss and shut down promptly after the power was restored. I am very satisfied with the design of the unit and the installer did a great job!

I know the generator runs weekly, but I have never heard it! It just sits quietly, waiting for the power to go out. Earlier this month we had a large storm, and lost power. Within a minute, the generator had started, and all I had to do was re-set the clock on the microwave. Now all the neighbors are being very friendly! This is probably the best addition I could have made to our house.

The general speaks for itself I'm enjoying it very much when the power goes off I can continually enjoy my day at home whether it cooking cleaning or whatever I do t have to sit around and wait for power to come back on and great features to keep everything running in your house. Thanks Generac

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.

Good product. Very good documentation. Installing a generator and transfer switch was a lot of fun for me. There is plenty of reference material on the web to help size gas pipe and wire and conduit. I used all 600 volt rated wire in pvc conduit. I was not impressed by the multi conductor cable that dealers were quoting. I'll be able to do all maintenance on the unit. Hopefully I won't need any warranty work.

We have not had to use our Generac system yet, but just having the peace of mind knowing it is there is worth it. We have 4 month old twins and live outside of town. If we lose power due to an ice storm it could be days or even weeks before we regain power. Knowing we will have it available as soon as our power goes it is priceless!

I'm no expert on generators. But my electrician is. I bought this generator on his recommendation. It could not have been an easier purchase & delivered right to my door. It was hooked up easily (by him) and looks ready to go in the yard. It is smaller that we thought for a 22w and we are very pleased with the purchase. I can't speak to the use as yet, but we are ready when the time comes.

Apart from the weekly tests we have had one opportunity to see the generator in action when a nearby transformer failed. We had full power restored within a minute, and seamless transfer back to utility power once the repairs were complete. My only complaint is that as an engineer, I'd like to get more data from the weekly tests. All I get is "It started, it ran, it stopped". I would like to see logs of fuel consumption, oil pressure, temperature, and generators output. I've asked about this information but my requests went unanswered.
