Great service - very professional. Jonny and Jared, service technicians, did a great job of installation. 1 Stop came very highly recommended and they met or exceeded the reviews. I would refer them to anyone looking for a back up generator. Baumie

This unit was purchased to replace a 20 kw destroyed by a flood. There was no hesitation on selection based on 9 years of wonderful performance by the 20 kw unit that was lost. It performed on numerous occasions and was responsible for a number of neighbors to follow our example on going this route. We feel secure and confident living in a rural area with outages that are too frequent.

Installed January 2021 (almost 4-years ago) and already have 231+ run hours since. We have this paired with the 200-amp automatic transfer switch. We also have PWRView installed which has helped us monitor and track down our power hungry forgotten gremlins. Where we live, we have frequent power outages, sometimes for weeks. Generac 24kw model 7210 is peace of mind. We actually are in the middle of a giant widespread power outage in the Greater Seattle Area right now (power outage started November 19, 2024). Thanks to Generac, we have 100% of all our electric conveniences without interruption. Paired with Starlink Internet, we have an Uninterruptible Life plus Full Connectivity. We have the Guardian 24kw exercise weekly for 15-minutes (12-hrs runtime annually as proactive exercise). Weekly exercise ensures the oil keeps the engine lubricated. I changed oil at 50-hrs and again at 200-hrs. I keep extra filters + oil in-stock so I can maintain during a prolonged outage. More than enough power to operate our entire extra large home AND charge my electric car with ease. With 4,000 sq ft and 2 kitchens - we can run everything without worry about rationing: 6+ refrigerator/freezers, 2-pumps for septic, electric heat, multiple large 80"+ plus sound system throughout, jacuzzi tub, plus 3 large portable a/c units in the summer. The Guardian doesn't ever hiccup. Our day time idle power draw is 2kw and overnight it's about 650-watts, which means the generator idles most of the time at <10% power draw. Thanks to the Guardian with advanced fuel management, we burn less than 1/2-gallon/hour of propane or less. Economies of Scale, by sizing up our generator large enough to operate everything on-demand we also benefit from the improved fuel-efficiency-per-watt of larger generators. We buried a 1k gallon propane tank so we never run out of propane during a power outage. This provides us about 90-days of generator fuel supply. We have a second 1k gallon propane tank to ensure we have plenty of furnace heat + hot water. Our typical annual fuel consumption is about 1k gallons. During one particularly bad snow storm, we had 18+ inches of snow and ran out of propane plus no electricity in 15 *F weather. Before the next winter I had this Guardian installed. I swore never again and over-engineered to ensure that. In our area, we have gone as long as 3-weeks without utility power and about 4+ weeks between propane fuel resupply due to deep blizzard snow. I also took the time to re-balance/re-wire the breaker panels when installing this generator. Typical USA homes have two 120v power legs. In our house, 90% of our power consumption was on one leg which meant our generators had to run twice as hard with half the power on the second leg completely wasted. By re-wiring our breakers specifically to re-balance all our electric throughout our large house we were able to improve our efficiency immensely. Our electric load is now evenly balanced which allows our generator to operate even more efficiently. Thanks to the convenience of automatic standby, I have been able to travel for work during inclement weather and the generator powered the whole house without worry. The generator has performed flawlessly while I have been away from home. Zero training required for the family once installed professionally. The Guardian is very quiet, even so I had it installed out by the barn. This means that we often lose power without realizing it because we can't hear the generator inside our house. The Guardian takes about 30-seconds to startup before supplying stable clean power. For those critical circuits (wifi, security system, routers, starlink, computers) I have installed several battery backups to bridge the 30-seconds. Due to our jobs (technology + healthcare), we require 24x7x365 connectivity and utilities. Our Guardian has empowered us to remain connected and impactful while working remote during the worst storms.

I have been contenplating either solar or generator for a while now. I got an estimate for both and decided for the generac because of the words of other people I know, the looks of the unit, other reviews, and the installing company information. I also have used the installation company for other work in my home and the employees have been professional, polite, courteous, leave a clean work site when completed, and were on time.

Documentation received with unit doesn't match what you see on the screen on the control panel. Documentation doesn't match the online app downloading and setup process. Setup for the app is pure mystery. Something about choosing built-in WiFi, WiFi access point, or LTE. No explanation of what to choose. In the end, once I got connected there were no useful features that would require online connectivity unless I paid $50-$60 per year and even then, nothing essential to operating this thing.

Moved to Florida last year and have been wanting to get a Generac installed, today my wish came true! She's in and ready to go. Found a great certified Geneac contractor on the web site. From estimate to install he was top notch. On time, fair pricing, a pleasure to work with. Now we feel safe should any storm come our way.

Having a generac generator gives me piece of mind if my power goes out. My section of the neighborhood is the last to have power Reconnected after an outage-last time it took 4 days. Now I don't have to worry anymore. The generator excercise(Test runs itself) and sends me and the installer an email that everything is working fine. That is a great feature to have

I dealt with power outages frequently so adding a whole house generator was a must when I built my new home. I moved in on a Friday and storms came through and I was without power from Saturday to Tuesday. BEST INVESTMENT EVER. And I am not mechanical but wanted to give the generator a break while at work on Monday. It was so simple to shut it down and reset it when I returned. Just the push of a button and life was powered back up. It does an awesome job of powering the house without any effort on my part

This 10 kw, 7171, is a great replacement for my 10 year old portable unit. No more pulling cables from the shed 65 feet to the house, and gas cans. Actually looking forward to a power failure. Once everything was assembled installation was about 5 hours. Love it

We had the Guardian 22 kw generator installed a few weeks ago. It is completely automatic - utility power goes out, generator power comes on - utility power comes on, generator power goes off. It is attractive, quiet, and easy to program. I can't wait to see it operate under actual no power conditions.
