Cabin generator
5 out of 5 stars review

Bought the generator last fall but did not put it into service until about two months ago. Everything is working as expected and looking forward to no problems with this unit.

Terrible Purchase

Purchased a month ago and it is still not operational. Both installer and generac have no idea why it is not working. I am Currently going through the loan company to see what rights I have

Hurricane Preparation

I purchased/ installed the 24KW Generator to power the whole house in the event of Storm outages during hurricane season. I have yet had to use it for house power, but confident it will work as advertised.

Easy Set up

I had a 5000 watt generator( 13 horse Briggs and Stratton ) I bought for Y2K and this is a huge upgrade for me and I only have to hook it up once this time. 😊. It’s always ready for me now. Thx. 😊

Great features

We bought our generator a month ago and are very pleased. We had a problem free Generac generator in our previous home that we were very happy with, which lead us to buying another in our new home.

It works

After 19 years we replaced our old Generac generator with this slightly larger, newer version. I like that the air conditioner doesn't bog down the generator. It has no problem running our modest home.

Piece of mind

Had it installed a few months ago and have not worried about a power outage since. Great piece of mind especially with all of the storms happening this year.

One year - no issues

Has been installed one year. No issues. Performs a test every two weeks. Operated properly during two brief outages, less than 15 minutes. App works well. Having a generator provides a peace of mind. Glad we had it installed.

Excellent home improvement project

I bought this a year ago and we had an outage a week later. Worked great and during 2 other outages. Installation was quick and fairly easy for the vendor. Saved us from cold days and loss of money from spoiled food.

Seems very capable if needed

Bought it 2 years ago and has only run for a 6 hour planned outage. Feel it’s a very capable generator. Electric grid is pretty reliable so hopefully it won’t get much opportunity to run.
