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 business owners to check the status of their generator from anywhere in the world, using a 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 will decrease installation costs.

Rated 4 out of 5 by from Weekly Startup Error It has been great and I have used it five times already. One thing that gave me trouble was that it did not start on its weekly startup and through an error message. After that it did not start on the next power failure until we figured out how to clear the error message. The red light should have been on if it would not start on the next power failure. The light was green! We check the display every week after the weekly startup to make sure there are no error messages.

Rated 5 out of 5 by from This product is the best on the market... To say I was "skeptic" was an understatement but boy was I wrong. I had this generator installed in January of 2015 (after putting it off for over a year). This is the best investment I have made in concerning my home. The product works exactly as advertised, it is quite, and you don't miss a beat when you lose electric. Why I didn't have this installed sooner is beyond me. So glad I did as it has come in handy 5 times since we installed it and it worked perfectly.
