Has Never Worked - multiple faults and service

Installed two months - 1 power outage - unit failed. dealer has been out 8-10x. new motor, new wiring harness. every sensor has displayed multiple faults. total piece of junk. I have had a green mobile link status 2 days out of 2 months. At this point Generac should be refunding me my money and removing this unit! it has never worked. think there are serious electrical / computer issues with this brand. all my neighbors that have generac told me it took several months to get them sorted.

Works great when not triggering error messages

This is my second home with a generac and I am very disappointed in the new unit on my current home. It keeps encountering errors after it starts running which defeats the purpose of having a generator. It's terribly disappointing to spend so much money to prevent energy outage at our home/business, but with no better outcome than others that have not installed a generac. I truly hope that this software issue with our new generator will be resolved soon by generac.

We love our Generac!

We had our Generac installed during the winter. The process was handled with care and patience. We have family and friends with Generac home generators and we heard nothing but good things about them. The generator is turned on remotely once a week to make sure everything works properly. It's so good to hear it running and to know it's ready at a moments notice.

Seamless operation during power outage

Weekly test runs are going fine: starts on time and idles low after a short run at full speed (so it is much quieter). First power outage and the transfer switch, generator and power supply started, ran and shut off seamlessly. Impressive. The only improvement would be if it were not that loud: can be heard clearly in the house and even might affect level of speaking or certainly could affect getting to sleep.

Love our Generac❤️

We have been thinking about buying a Generac for years. So glad we finally did! Our neighbors had their installation done in 2018. Every time a storm caused an outage, they were completely comfortable, up and running! It has made us feel much more secure with the hurricane season coming.

New and improved version

Just installed and completed and we have no issues. Had to leave our first Generac at the old house and now have the new and improved version. The simplicity of managing is great, have recommended to our neighbors and they are being installed and ordered as I type.

Seamlessly continues power supply.

I bought this unit for a rental tiny home on my property. I had already installed a 17kv Generac which services the main house. We have electrical outages several times per year in our rural location and our Generacs work flawlessly to seamlessly continue to provide power when this occurs.

2026 Generator SUCKS!!!!

We purchased a brand new 2026 Generator. It is now April and the thing still does not work. Every time the power goes out ... the generator runs for 5 seconds and then shuts down and we get a "failed" message. Our installers (Blue Sky Plumbing) has said they have installed 23 of the these same generators and ALL OF THEM are having the same issue. I would not purchase a new generator again from these people and if we don't get our money back ($50K), we will be suing Generac.

Runs quieter and has great App features.

We bought this 24KW four months ago and was only able to get it installed a month ago. So far we're very pleased with it. We bought a 22KW Generac 20 years ago and got a lot of usage out of it in south Louisiana. Back then it was referred to as a "whole house generator" but we soon learned that didn't mean you could run "everything" in the house on it. It running under a load because of a power outage and my wife was running the clothes washer, dryer, microwave, the electric oven and all the lights at the same time and it handling the load just fine until our 3.5 ton AC kicked on and it started to bog down badly. Lesson learned!! We have only used this one in the exercise schedule and not under a load yet. It is quieter than our old one though. Be sure to get the App for it if you want a more detailed status of it and setup an exercise schedule.
