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.

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!

Excellent from installation to education

This is our second Generac as we recently moved to Florida and had to leave our other Generac behind. The feeling of security it provides, and the almost instant continuation of electric service to our home, is worth every penny of its price. Our Generac dealer made the entire process simple for us, taking care of each detail involved with the installation. The instructions provided were simple and clear, and they made sure we knew how to reach them with any questions or concerns we might have. Overall, the level of comfort having our Generac installed has made us more comfortable in our new home.

Happy with our Generac

We purchased our Generac from Calibre Electric in Burlington, Ontario. The install was done quickly and the techs were courteous and showed me how to set up the Generac Mobile Link on my phone so I can monitor the machine. A few weeks after the install we had a half day power outage, the generator kicked in promptly and my wife had AC so all was well. It runs a little noisy but with the windows closed we didn't mind. I would recommend to gardeners that you not locate your machine close to plants, as the heat from the exhaust will not be kind to your garden.

Portables are nice but whole house clearly better

We purchased a portable generator back in 1999 and used it several times throughout the years. But we are older now and the effort to maintain it and get it operational has become more challenging and so a whole-house "automatic" start generator made more sense.

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.

Comfort Backup

Purchased in 2024 to connect with our EnPhase solar and battery backup system. Electrician did a great job and I plumbed the LP line. Checked the LP with manometer and all was/still is, good. Generator has performed as needed during the outages we get often, even when the solar array is working and below the settings for generator assistance. I perform my own maintenance and use OEM parts. The generator charges the batteries quickly to help save on LP costs. Nice to know we are covered!

Great performance

Generac 22kw generator was installed on June 17. Our power went out July 3rd until July 5th, 40 hours. The Generac kicked in immediately and allowed us to keep lights and AC on and stove, water pump, water heater and more running the whole time, with 9 people and four dogs in the house.

Looks good and quieter then my portable generator.

We purchased ours a few months ago and had it installed about a month. We were going to use the existing switch we have with our solar panels and the EG4 batteries but come to figure out we had to get the switch installed by the company that installed our unit because the place to connect to the EG4 inverter was being used by one set of solar panels that was running on AC. If that set of solar panels was DC like my other set of solar panels then we could have used the EG4 inverter and saved a lot of money. Installation was done without any complaints and looks very nice. We only had the unit come on for a check so don't know how it will be when the power goes down which just happened a few days before the unit was installed. But our EG4 batteries did just fine. Don't know how much more to say except we are running it from a new 500 Gallon LPG tank they installed just for the generator.

Happy with everything, the Dealer, the product and the installation. However I feel like there could have been a better job restoring the landscape after digging a trench for the installation. They left it a muddy mess. Should have been packed down, raked, seeded with hay.
