Time saving, great device!

My wife t thought I was crazy for buying a stand-by generator because we have a generator that I double hook up to run a few things in the house. Now since we have the generac she sees how handy it is and I don't have to go outside in the freezing cold or rain in order to "hook up" the other one!

Has never worked

Has not worked at all. How Generac can release a product that has software issues. I paid all the installation and equipment money for a product that has never worked.

Love owning a Whole House Generac Generator

We have only had the generator now for less than a month. Luckily we have not had any power outages and have not had to use it. I will say, that when I hear a storm is coming our way, I do not panic or worry about having an outage.

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.
