Rated 5 out of 5 by from Excellent Machine - WiFi Mobil Link (not so good) Unit works great on Auto mode. My biggest complaint is that after repeated attempts to get the Mobil Link set-up between my cell phone, the generator set, and the automatic transfer switch, it is still not able to communicate with my cell phone. To me, this is an absolutely worthless feature and is probably hundreds of dollars (that I paid) that was needlessly spent. A feature that doesn't work easily and intuitively isn't a feature. I have given up on trying to make this work. Generac needs to send someone to my residence and get this working for me.

Rated 5 out of 5 by from Great Generator and great install The installation started out complicated but the crew really did a great job installing. They also gave us a great education on how it works and what to look at. It is small enough that it doesn't look bad in our back yard. Not too noisy. Our power went out the day before the generator was installed. Within a month after installation the power went out on Mother's Day for about 4 hours. The generator was great and we enjoyed my day.

Rated 1 out of 5 by from Often Has Trouble Starting Our generator was placed into service on 10/7/2022. Since then, it has often failed to start for its weekly exercise period (on10/11/2022, 2/8/2023, 4/6/2023, 4/10/2023, 4/20/2023 and 5/12/2023 to be specific). It keeps the service technician very busy for a seven-month-old machine. We have very little confidence that our generator will start if we experience a power outage.

Rated 5 out of 5 by from Platinum Groupswere wonderful Platinum Group did a fantastic job with the installation of my generator. They walked me through the trouble shooting which was really really helpful. Great purchase for peace of mind - I would recommend a Generac and Platinum Group for a job well done

Rated 5 out of 5 by from Commending the generator installer electricians I would like to commend the two electricians who installed our generator, Nick Blakeman and Jake Blakeman, from Great Lakes Electrical Contracting. They arrived on time, worked with the plumber and afterwards with professional efficiency. When the job was done they went through some features and directions and suggestions with my wife and I, and set us up with our wifi and the app to use. They were a pleasure to deal with in every way.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Great features, reliable and looks good outside the house Mike, Aiden, Damon and Andrew from Adam's Electric did a super job of the installation and cleaned up everything. I'm susceptible to outages being out in the country with many trees around and I love the reliability of a Generac unit backing up my home.
