An Infant and a sump pump

My power was going out on a monthly then turned into a weekly basis. I spent so much time on the phone with DTE to get daily or hourly credits for my service being down. This made life difficult with an infant and a sump pump. I invested in an 18KW whole home generator, this was the best home decision I have made. No more am I using the stove to heat in winter and window units plugged into a portable generator in the summer. With a sump pump you only have so much time to get the power to it before it fills and spills over into the basement. Oh and let me tell you, how difficult it is to set up a portable one when you have an infant that doesn't sit still. Generac, You are a life saver and I tell everyone!

Peace of mind

I bought this unit about a month ago, and so happy that I did. Within an hour of the install, we had an outage, and the generator kicked in within seconds. Being an elderly couple I wanted peace of mind that all systems, would function, appliances, well, heat and air everything is electric.

Features are okay. I just need it to run.

The unit threw a rod in January of 2025 and threw 2 more rods in 2026 with a sum total of 115.5 hours of run time. I can see a unit going down once and being repaired, but twice for the same thing, even Generac should recognize there was and is a problem. Generac finally fixed it but after months of waiting. I would not recommend a Generac to my worst enemy because of Generac's reluctance to make it right.

The number one feature is the Mobile Link App

I bought this a couple months ago and the installation was finalized this past week. It has not been in service yet but I know it will be there next time we have a large storm and loose electricity. The generator is very well built and the installation was top notch.

It has scared the utility into behaving!

Bought this last year (2025) and it is comforting to know that it is there if I need it. For some reason the utility service has been good and we only had one power failure to test it. Worked very well. It is thunderstorm season now so I am hoping it will run for a few hours.

Generac - Great investment

The Generac has already run three times, and each time it worked exactly as expected. It gives our family peace of mind knowing we have reliable backup power whenever we need it. We are very satisfied with our purchase and the confidence it provides during power outages.

A great Investment!

I purchased this 1 year ago and could not be more pleased. My wife and I both work from home. So, power outages which are becoming more frequent are disruptive. It's large enough to power our entire home. And the cutover is pretty seamless. We also have cellular backup for internet connectivity which is a super-solid combination.

Outstanding reliability and performance

A little over a year and several long power outages, this thing has performed flawlessly. There are 2 homes in our area that stay lit up during an outage, my mom's and mine. It was comforting to see her Christmas lights on when the neighborhood was dark.

I bought this a few weeks ago, already storms have gone through on two different occasions and knocked out our power. The generator has preformed flawlessly on both occasions, running for approximately 23 hours total for both occasions. My neighbors are jealous

We've had it for a month, and I would have bought it way sooner had I realized how much comfort there is in just knowing it's there. We don't lose power here, but I DID stress every time they predict freezing rain, and we did fill buckets of water in the bathtub for toilet flushing every time they predicted bad weather. Now I can forget that stuff and just enjoy life. That's priceless.
