Excellent product

I had this generator installed and the first night we lost electrict power and the Generac kicked on in just a few seconds. I am very happy with the Generac. The company that installed the electrical services were very knowledgeable about the generator and very professional in their insulation.

Buyer's remorse

When it works it is great, but it does not work consistently when needed. Red light keeps coming on and I question the decision to purchase this. No sooner did I get it paid off all my problems started and I have been dealing with gremlins ever since. Really do your research to make sure this brand is what you want.

24Kw

I gave it a 4 star because I haven't had to use the services yet. The installation process was done very professionally and in a timely manner. Had an issue with initial startup of the generator but got everything going smoothly. I did find the wifi connections a little difficult but finally got it connected later the next day. I would recommend Generac to anyone.

Why does a 180 amp generator have 100 amp breaker

We installed this product, waiting for final startup. The generator has a 100 amp breaker yet is sold as a 22kw whole house backup. Granted that we probably don't peak over 100 amps very often but I was not clear that the product was limiting itself.

Great Protection all year round

We love our whole house generator so now we don't have to worry about being without power. We upgraded the WIFI feature to cellular service for WIFI so that we don't even have to rely on our home WIFI. The warranty on the generator is great and gives us lots of peace of mind. If something goes wrong , the company can look at the generator remotely at any time and diagnosis the problem quickly. Great Product and highly recommended.

Smooth process to get it up and running

Samuel and James from Holly Electric did a great job throughout the install process. Explained the operation once it was up and running. Heather did a great job of keeping me updated through the entire process from quote to install. This unit replace an smaller generator that was only able to run a few appliances and lights. Nice to have whole house comfort now. Have a 250 gallon propane tank to ensure we can weather through a hurricane or sever storm.

Automatic features are great

This automatic generator gives us peace of mind in the many storms we have to deal with in South Louisiana! It has a weekly check to make sure all is in order. The installation by the very qualified dealer was done quickly and without any problems. I will definitely recommend this product!

Excellent choice

Amazing the ease of Installation. The Smart Management Modules were easily installed and what a great idea. Very versatile design that covered several requirements in our installation. Open the lid on the Generator and quality is noticed immediately. Even making maintenance easy and simple was designed into the product.

This is a fantastic product!

After considering purchasing a stand-by generator for several years, my research led me to Generac. It is a quality product that requires minimal routine maintenance and provides great peace of mind. I will definitely recommend Generac to my friends and relatives.

Good generator but could be better

Since installing the generator it has come in handy a couple of times. Paired with the automatic transfer switch we are covered when the power goes out. I do wish that there was a little more customization available to the running parameters. It would be nice to be able to set the transfer switch to run for a minimum time on the generator, say 5 to 10 minutes, if power is lost. There have been several times that we lost power in high winds and/or severe thunder storm where the power went out, generator kicked on and transfer switch swapped over and within seconds to a minute the power was restored briefly (just long enough for transfer switch to swap back to utility) and then repeat… Having a minimum set run time could minimize the possibility of the multiple swap overs and damaging electronics.
