What Makes the Protector Series Such a Great Choice?
Generac's Protector Series offers benefits that competitors can’t match: installation flexibility and cost reduction. Sophisticated, yet intuitive controls. Quiet operation. Supported by a 24/7/365 customer support team at our corporate headquarters, and a nationwide dealer network of more than 6,000 strong.

A cutting-edge, intuitive control. The Evolution controller features a multilingual, two-line LCD text display with color-coded, backlit buttons. It has received upgrades, including USB flash capability, smart battery charging, voltage adjustment, and backlit membrane pad-style buttons.

5-year limited warranty, with extended warranty options available.
We are proud of our innovative product design, high quality and first-class reliability so we stand behind them with a strong 5, 7 or 10-year limited warranty.

Can Be Installed Just 18" From a Structure
Capability to be installed 18 inches away from a structure, ideal for areas with tight lot lines. Generac is the only manufacturer of standby generators to have 18” offset on most of its residential lineup.

Tough, Durable All-Aluminum Enclosures
Our RhinoCoat™ powder-coated finish helps make corrosion-resistant aluminum perfect for all weather conditions.

Quiet-Test™
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 optional 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 3 out of 5 by from It is difficult to write a review on a not-yet-functioning unit. The unit is pretty, all bright and shiny, a very expensive yard ornament. It arrived and was installed by very courteous, dedicated, knowledgei ble individuals, but when the test run began: 1) The unit would not start. A technician was called, and the installers departed. 2) The coolant was low. After being filled with coolant, the unit still would not run. The technician determined there was a bad #3 coil which had to be ordered. I am awaiting completion of all services and testing before I decide the value of my purchase.

Rated 5 out of 5 by from Generac is a terrific product My Generac generator was installed by Oakwood of Westmont. I have used Westmont for maintenance of my old generator and they have always done a terrific job for me. When it came time to replace the old generator, they were the obvious choice. As expected, they did a great job, made the process easy and the team that installed it could not have been friendlier or more efficient. I can't imagine using anyone else for generator needs. JJ

Rated 5 out of 5 by from One thing mission Unlike my old Generac, there is no way to prevent anyone from having access to the controls except for a plastic cover and place for a small lock. This is a serious defect from the stand point of personal protection and home security. If I had know this in advance, I would have looked at other brands.

Rated 5 out of 5 by from Need to add a feature Wish installers had told me which end the muffler is on. I would have had the unit reversed so the muffler was away from a bedroom. I have natural gas for a 25kw unit. Reversal would be easy if the gas line was available for hook up on each side. When I looked in the unit, there was space to have the gas line hook up available on both sides.

Rated 1 out of 5 by from You need to advise customers better.... This generator runs at 3600 rpm and sounds like a runaway freight train. There is no way it can last as long as the 1800 rpm engines. Generac should make this clear to its customers that the noise made from this generator is substantially more than that of the 22 kw 1800 rpm engine. Very disappointed in its customer relations department.

Rated 5 out of 5 by from Came on when needed just like it was supposed to Bought a year ago and haven't needed it until this week. It switched within seconds and It has been running non stop for 65 hrs. Finally gave it a break to check the oil. Avg 1.5 gal LP per hr. The power has been excellent and it handled all the appliances when needed. Much quieter than the portable units my neighbors are using. It would nice if it had wifi or bluetooth.
