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.

50/50 feelings

I wish I had better things to say but I feel the company that installed the unit did a poor job the unit leaks oil and when I told them about it on the 1st maintenance visit, they wanted charge me extra this was part of the installation and has been leaking ever since . Other folks may have a better experience with this brand I think it was just the company that has installed mine .

Bought 2 months ago and not satisfied ,Contractor had to Come 4 weeks straight to deal with low fuel pressure fault/shutdown during weekly exercise. Not very confident that generator will work properly during loss of power due to these issues Contractor who installed where outstanding

26 kW backup generator

Again, my problem is with the electric company that installed it rather than the product itself. But unfortunately, I have not had the support that I would have requested. I.e. asking for a quote for the extended warranty never getting one if Generac can offer that to me now I would be receptive.

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.

Best Home Purchase

I have had my generator for 1 year. Love it. Great investment. Peace of mind just knowing that it's there. I have used it a few times, generator comes on seconds after a power outage. My home functions don't skip a beat during a storm. Definitely recommend.

It comes on when power goes out.

Had 15 different power outages in the last 12 months and some outages lasted days. We have had no power outages yet sense we bought and installed the Generac generator. Now when storms come I'm not worried about power loss but I am scared of tornadoes.

Generator performed perfectly.

We had a bad thunderstorm yesterday and lost power for a couple of hours. Our generator came on and worked perfectly. We would not have known the power was off and the generator had taken over if it had been for us hearing the generator running and the light blinking. I gave a 5 star rating because of the way the generator has performed even though I am still not happy about being put off about the damages,

Excellent Great installation, look great Very impressed with the Installers effort to evaluate our power requirements He contacted the local utility company and found out our average and peak power utilization from the past two years and installed a system that will totally support the whole house
