Although I am impressed with the overall quality of my 22kw Generac generator & transfer switch, unfortunately I did not do enough reserarch & was surprised to find: 1. It runs at roughly 1/2 speed (2.5gph LPG) with no load. Regardless of what their engineers claim, there is no excuse for this with today's technology especially since it already drops from high rpm to idle when exercising at no load. It should match rpm to load like most portable units do. 2. I am unable to turn it off & on remotely with my smart phone app. I would think the existing software could do this safely. It appears at least one other manufacturer offers this. 3. The transfer switch does not indicate when load is from utility vs. gen unless you open the cover & note the relay position with a flashlight (or remove the inner cover). Note it does include a switch you can wire your own indicator light to. 4. There is no user display of output, i.e. watts, amps, volts, frequency. Generac confirmed a dealer can access volts & frequency on the generator display but not load. Although I have all the meters to measure these for testing, there needs to be a full time digital display on the transfer switch & on the smart phone app. My experience is as an industrial engineer & building contractor.

My 22k standby was run for the first time today. My install contractor ran all the tests and walked me through everything I needed to know. I travel quite frequently and always had a concern about my family being alone in a power outage...which happens quite frequently in our area. I am completely satisfied with the purchase and with my contractor. Peace of mind is a great thing!

Finally made the leap and had the 22K installed for our home. Product appears to be well made and will provide all the necessary power to keep our large home up and running. We have required durable medical equipment and power is a must!! Installer was knowledgeable and meticulous. Two transfer switches, generator and one power modulator as well as buried power and gas lines and you can't tell he was ever here. Generator ran its weekly test right on schedule. We are ready for "old man winter"

No more messing around with a portable generator, trying to pull the cord to start it, filling it, being sure we have enough cans of gas for an emergency! Hoping we are home when the power goes out so that we can start the generator going, or if it runs out of fuel. With our Generac 22KW Guardian whole-house generator, we don’t have to worry. Nice-looking unit. So quiet compared to portable generators. Best features:Transfer switch kicks on automatically whenever there is a power outage. Powers up and checks itself periodically, green light/yellow light/red light alerts us if something is wrong. Overall, a great investment that adds value to our Florida home if/when we want to sell. Love it!

I have two complaints one is on install there were 3 holes drilled through a brick wall one for the holes there was some chalk put in but was not put all the way around the hole and a lot of it run out and had to be cleaned off the brick the other two holes was left completely unsealed. I had to seal all three holes myself. The other issue is the insulation pads in the top. the pads fell down several times the glue from the factory was vary insufficient. I bought some 3M 90 spray adhesive to hopefully fix the issue. Other than these two issues the unit seems to work great, time will tell.

Everything about this generator is excellent. The only two issues were we had to wait 18 months to get it installed because the dealer couldn’t get it from the factory in a timely fashion. Also I was denied the free extra warranty because I “bought it before the program date”. Even though I didn’t get it delivered to me. Not cool. The dealer did a great job on the installation.

Stuller's process of providing the initial sight analysis, listening to the details of what I wanted updated and changed was very pleasant. They followed up promptly with a comprehensive proposal & estimate with a clear explanation of each system component. This gave me the reassurance they had the experience and expertise I was looking for. In addition, they provided fair pricing and even took the time to correct errors identified in our original generator installation. Their attention to detail and pride they take in their work was impressive! Thank you for a job well done!

Our electrician - a true perfectionist, and among the most honorable men we've ever met - has installed hundreds of whole-house generators, and won't recommend anything other than a Generac. He swears by their reliability, quality electrical components, sturdy and rust-free enclosures, durable engines, and the clean current they provide. During installation, he opened the generator and pointed out all the elements of Generac's thoughtful, maintenance-friendly design. All in all, it's obvious why Generac is the dominant player in whole-house generators.

We tried to face quite a few Hurricane Seasons with A Gasoline Generator and Solar back up. Both were not adequate. Also living in a contry setting, all electric includin Well for water and freeze up happening in the winter we decided it was time to be really ready. The demonstration after hook up enforced our faith that we should not have to worry any more.

Generator Supercenter in Lufkin, TX was our provider. Once we were informed of our install date, everything was flawless. Install team were very professional and knowledgeable. I would highly recommend Generac. They certainly have a winning operation from start to finish.
