Rated 3 out of 5 by from Trouble starting First attempt at starting it immediately dies. Second attempt it starts. Any other propane motor I have ever heard of starts immediately with no problem.

Rated 5 out of 5 by from A+ product and excellent installation by Generator Exchange Ordered the 24KW unit in July of 2021 and finally got it installed in April of 2022 .. long backlog here in Houston post the big freeze in February 2021. Generator Exchange did a fine job with the installation which was a one-day job, post-pouring the mounting concrete slab. Ony hiccup was that the load shedding (SMM)) modules didn't seem to work at first with my 3 AC units. Generator Exchnage swapped them out and then we actually had a briefd power outage the next day, the genertaor kicked in for 10 miniutes, and the units worked flawlessly. Now waiting on the WiFi kit to finish the job.

Rated 5 out of 5 by from Excited with the Wi-Fi feature. So wi fi is a great feature because I’m a widower and know nothing about motors. This way my phone will alert me to issues or maintenance needed so I can get a serviceman out to handle it for me. Generac has always been our brand to go to for generators etc. They are very reliable and dependable. Love it. The support group got me registered and a code for wi fi in no time at all. They were very friendly and polite. Services received means a lot to a person so Thank you for your kindness.

Rated 4 out of 5 by from Costly but neccasary! Most of my buying and install was a very good experience. Everyone was friendly and eager to answer my questions. My one big complaint is there was no low stage propane valve installed when the gas lines were installed.The propane company now has to install a low pressure valve on the generator at an additional cost to me. Not very happy about that as it should have been installed when the line was installed. When your sales guy comes to your house ask questions! Get everything you expect on the quote!

Rated 5 out of 5 by from Excellent choice Amazing the ease of Installation. The Smart Management Modules were easily installed and what a great idea. Very versatile design that covered several requirements in our installation. Open the lid on the Generator and quality is noticed immediately. Even making maintenance easy and simple was designed into the product.

Rated 5 out of 5 by from We like how this generator works My wife and I wanted a home generator that would work automatically and switch on when the city grid failed us. We get this and more with this model capable of running most of our house, testing itself weekly, and monitoring its status. Furthermore, it communicates with my service advisor to quickly notify him of issues and facilitate a rapid resolution before a little problem becomes a big one.
