Junk wish I would’ve went with a different company

L I bought this generator less than a month ago and it broke down within the first month installer keeps canceling my appointments to figure out what’s wrong.

Peace of Mine

This is what we needed for complete peace of mind. Starts automatically (we don’t have to be home), notifies us of status, and let’s deal know if there are any issues so they can plan to service the unit (we don’t need to figure it out and call them). Keeps our life simple and worry free.

Something is Wrong with it

I bought this a month ago and it’s still not working properly. It runs for 15 seconds and then shuts off. After five cycles of this it stops altogether. They are still trying to figure out the issue. I am happy to review again once it works properly.

Good generator for the entire house.

Have had this generator for a year. Had to have a faulty emergency switch replaced (under warranty). I've put about 11 hours on it. It's able to power everything in my 2500 sq/ft house (A/C, Heat, oven, dryer) all appliances with no issues.

Reliable Power

Just completed year two annual maintenance. Generator has activated reliably 5 times over the past two years and powered my home without any issues. Propane usage seems very efficient.

Fast and efficient.

I finished installing my generator a mouth ago. I have my first outage during a storm. The generator performed perfectly. I am very happy I installed this generator system.

Great Whole Home Generator for my house.

I purchased this one month ago and could not be happier. The installation went great. Generator runs like a clock every week for it’s week test.

Poor Product

Generator was installed and does not work. Installer is doing their part to troubleshoot. Extremely disappointed with the product, not the installer.

Disappointed Multi-Generator Customer

Generator delivered with poor communication device, poor dealer service/response, poor Generac support for Mobile link, and poor support for code clearing

Generator is great! Mobile Link app….not so much.

The unit was installed on a Friday and we lost commercial power for 23 minutes the following Monday. The unit operated flawlessly! The only drawback I’ve found is the inability to see realtime unit loading and voltage in the Mobile Link app.
