Reliable stanby generator

I bought this uint from Sam's club and had it installed by my electrician. I was not aware that the unit did not come with a battery. Overall, I would buy this unit again.

Happy With My New Generac Generator

I am very pleased with my Generac generator. The sales, installation and support processes have been stellar. I feel very confident that when the power goes out that we will be protected and safe with our Generac generator.

Peace of Mind

I had this installed the end of March and have already had one brief power outage but the generator started within 2 minutes! This is truly peace of mind.

Great dependable generator.

I've had Generac generators for over 30 years. Very dependable with little maintenance. They last for a very long time. I have so much peace of mind knowing my home will always have power.

We have the most updated Generac and it is working

Very happy that I bought this a month ago and that we have peace of mind now if the power goes out, I'm set as I do have medical devices that need to be run

Very solid generator

I bought the 26KW last month. And now I have peace of mind knowing if a hurricane hits here in Florida and I lose power. I will have little or no change in my lifestyle, because when the generator starts I will have power.

Bought this a month ago and so far I'm fairly satisfied. Have had a couple of problems with it and still haven't received in paper my paperwork for my 10 year warranty

Great except the battery

It's great to have a backup whole-house generator for emergency situations. The only negative is the battery only lasted one year. I have a five year warranty and the battery isn't covered.

Since the purchase of generator it has only run for about an hour when public service was working on their lines. So I don't have much of a reference.
