All backup generators run a weekly test to ensure the system is running properly. Thanks to Quiet-Test, your Protector Series home generator runs its self-test at a lower, quieter RPM, which can be programmed to run weekly, bi-weekly, or monthly.

Mobile Link™ Remote Monitoring
Mobile Link is the cellular remote monitoring system from Generac that allows you to check your generator’s status from anywhere in the world using your computer, tablet or smartphone.

Additional Features
Improved stub ups and electrical connection access decrease installation costs. All connections are dual conductor rated, and the implementation of quick connects for the control wires, completely eliminates the need for crimping or lugging.
Improved customer connection access, which decreases installation costs.

Rated 5 out of 5 by from We’re ready for power outages now! Installation of the generator was completed this week. We have yet to use it, but no more worries about power outages affecting our lifestyle. We feel very secure with the Generac generator providing backup.

Rated 5 out of 5 by from It’s everything I expected! This is a great looking generator and at 48KW it will power everything in the house! After hurricane Michael, I used my Generac portable 15KW to keep the essential household items running for days until the power was restored! The quality of a Generac system is unbeatable!

Rated 5 out of 5 by from Keeping It Going I am thrilled to have my Generac generator installed and ready to “go” in an emergency.The brand is excellent (previously owned the same at a former residence) and installation by Premier Power Systems in Jacksonville went seamlessly. Bob Holman and his team are the best in the business.

Rated 5 out of 5 by from HIGHLY recommend for best technology at the best pricing! This is the second time I have worked w.Rusty and his crew @ Generac in supplying a generator for my homes. They were professional, timely, cost effective and knew exactly how to provide me the product I needed at the right price. The most recent installation involved multiple buildings on my property and Generac designed a system to handle the load I might need using great technology. I would HIGHLY recommend Generac for your needs.
