Not cheap but worth having. Reliable and aesthetically functional in just about any setting. Home builders should just start including them these days in my opinion they are that terrific.

Great addition to the homes value. The power just went out and all we saw was a couple of flickers and the it fired up and all is back to normal. All with in a couple of seconds. Cool !

This product is very quiet and very simple to operate. We purchased two of them. Very satisfied with product and customer service. Great support team of people.

I am impressed by Generac, but think that the sale, installation, and follow up secured the good rating. We were really pleased dealing with Optimize Electric here in Baton Rouge LA.

The 22 KW model we have is unassuming and just works as promised. Which is exactly what we wanted and expected, a quiet standby insurance policy against power failure.

Great product. This provides security of having electricity when you need it, and in rural Michigan, you need it. No more spoiled food, no flooded cellar, no more re-fueling problems.

The product is a great reassurance in my rural setting. It is quiet and efficient and in the two instances it was needed the switch over to back up power was not even recognized.

So far the generaton has worked as expected. Weekly start up has occured as scheduled. We have no complaints. Hope We really don't need it BUT If we do we have it.

This product is a good choice for residential use. It runs quiet and exercises itself as programmed. The value will not be realize till it goes active when the power is lost

I had this unit installed one year ago. The unit switched on twice for 2 minutes each time. I am very satisfied to have the unit available, especially during hurricane season.
