This is a very good product, the only complaint I have is It never came with a sticker for my elec meter that says there is a secondary source of electricity, just in case a firefighter pulls the meter in an emergency, please send me a MUST have sticker.

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,

Our electricity was off for the first time since installing the Generac on Christmas morning, lasting for about six hours. For me personally, the Generac paid for itself that morning!!!! So many things to get done and family arriving. I was able to get everything done with ease due to the Generac. I felt so blessed!!

I've had my backup generator for about seven months now. This is my second one actually, since my first was stolen a day prior to it being installed. The generator was installed by our electrician. I set up the programming of it, which was very straightforward. The power has only gone out once since then and it was amazing how it started right up, switched over and ran into power was reestablished. It automatically rubs through its test runs weekly without a hitch. It's a great comfort.

We already were in need of the use of our generator when our electric was off for a few hours. It immediately came on and kept our house warm and lighted. It is a relief to know how dependable it is when needed. It ran so smoothly I wasn't even sure the electric was still off.

I kept waiting for a power outage to see if the unit would cycle as it should and it performed perfectly when the outage happened. The unit is the required distance from the house and is barely noticeable when running. BTW: The installation was done by people that knew what they were doing in a very professional manner.

After building our new home on the South Texas coast and installing our new Generac with automatic start, we moved in in May 2017. Three weeks later, a huge storm hit and our entire town lost power. Needless to say, we were the only house on our street with power and, thank goodness, air conditioning. Our Generac was worth every penny -- we're so glad we installed it from the beginning!

We have had our Generac for about ten months. During that time we have had three or four power outages, with the longest lasting several hours. The Generac, in each case, started immediately and carried the full load of the house for the entire duration of the outage. We temporarily have a one-year-old and his parents living with us, so it was especially appreciated when we were able to keep him entertained and warm, as if nothing had happened. We have enjoyed our Generac immensely!

Purchased the model #6551 22kw system for my new house. Power interruptions in our area are typical and storms can bring outages that last for days. Haven't had a serious outage since installation but the unit cycles once a week for self-check. During installation the unit checked out against a full house load. My four star rating on features is due to the engine noise. Better muffling could help. During self-check the unit runs at a lower rpm and the noise drops by half.

I purchased my generator when I built my new home. When we were moving in the beginning of August we had a power outage the 2nd night for over nine hours. The generator kept everything working just fine. The sales team and installers at Winchester Electric are great to work with. I highly recommend this product.
