No problems with this 22KW generator

This is the second Generac generator. I move away from the first that was a 20KW on natural gas. I had no problems with it during the 7 years it was in service. I installed a 22KW on propane as soon I got settled here. No problems with this unit in the three months since installed. In Oklahoma we are subject to power outages any time.

Awesome generator

We have had this generator for 5 months and it was installed when we built the house. We had some storms come through this weekend in Mississippi and were able to use it for the first time. We were out of power for around 1 hour while we used it. It cycles once a month per my settings and when power goes out you will have power from generator within 10 seconds. When power from utilities comes back on there is no loss of power at that time. Only when you loose power, the reason is generator must warm um before it takes a load. Awesome product and for the price and performance of this unit it's a winner for all.

My Second generator

I bought one of the first automatic standby Generacs years ago. I hope the new one is as good as the old. The old one was plug and play on the wiring. New one is more difficult on wiring. Have to call or go on Internet to activate. They don't want the average homeowner to install, that's a missed opportunity. Good unit so far.

So great to have!

Have been wanting a generator as I have well water and live in a cold climate. Unbelievably, we had a power outage for 2-3 hours just a few hours after installation was completed on the day before a holiday! Switches over without a blink. Great service from my installing electrician, and extended warranty to boot. Couldn't be happier, and so relieved to no longer have to worry about weather!

Customer Service Canter Power Sys

After a flood I call the dealer that installed the system and they came out very quickly and restarted the system. Even though the water level went up the side of my unit approx. 6 to 8 inches. It restarted without any problem. My next call for service was when the green light turned to red. I called to get advise on what I needed to do. I never received a call back. It's been several weeks still no answer. I went ahead and restarted and so far the system is running and the light is staying green.

This generator provides comfort and peace of mind.

After Katrina in south Mississippi we were without power and water for 23 days. It was 105 degrees for several days. Miserable. Since then every time a storm would move into the Gulf my tension levels would go off the charts. We decided to fix the problem. In the fall of 2016 we installed a Generac 22kw propane fueled generator. Within 4 months we have lost power 5 times due to tornadoes and storms. The last outage the generator ran 10 hours straight with no problems. We were the only house in our area with lights. It was awesome! We don't worry about power failures anymore. We love this generator and it's one of the best investments we've made. I can't stress enough the peace of mind we have now. Thank you Generac for standing by!!!

22KW Whole House the way to go

I have had the 22KW Generac Generator almost a year now and has worked great when the power went off on several occasions. Living in a new neighborhood we have had outages do to construction in the area. The latest one was for about 5 hours, the generator did the job of keeping my house powered. The only way I knew it was running was it sounded like someone was cutting my back yard with a lawnmower. I highly recommend this generator for your whole house needs. I gave a 4 star on value for price not for the generator, but the installation cost.

22KW Installation

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.

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.
