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.

True Power™ Technology
Delivers best-in class power quality with less than 5% total harmonic distortion (THD) for clean, smooth operation of sensitive electronics and appliances.

Evolution™ Controller
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’s 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™ Connectivity
Mobile Link™ Connectivity allows you to monitor the status of your generator from anywhere in the world using a smartphone, tablet or PC.  Easily access information such as the current operating status and the generator's maintenance schedule. Learn more about Mobile Link
Mobile Link comes standard with Protector Series 22 - 100 kW gaseous models and diesel (RD) models.  The Wi-Fi device is standard on every Protector series generator except for the RG13090/RG15090 and the 130 - 150 kW gaseous models.

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 Exceptionally quiet. Best investment I've made. Have had 2 power failures in my area since install and generator never failed us. Has run over 20 hours in last month since install while we stayed comfortably inside.

Rated 5 out of 5 by from Great product except for shipping damage. The delay in getting the product was excessive. Upon delivery it had damages to the enclosure. It also was set up for natural gas and we are propane. We had to wait for the part to correct this before install was completed. We are still awaiting replacement parts to correct the damage to the enclosure. These are to come from the installing business. The unit is installed and operating even though it is pending receipt of the parts.

Rated 5 out of 5 by from Long Term Generac Generator Owner I had my first Generac Generator probably more than thirty (30) years, I actually can't remember how long ago we purchased it, maybe longer than thirty (30) years ago. It was a permanent installation on natural gas and I think if I remember correctly it was an 10kW unit and I never had an ounce of problems with it. I serviced it regularly and it exercised weekly. We moved from Southwest Kansas to the North Texas Area and immediately I started working on obtaining another Generac Generator, no questions asked about any other brand, it had to be a Generac Generator. Here we required a 38kW unit powered on L.P. Gas/Propane. It has only been installed a couple of weeks so I don't have much of a track record, but I don't expect any issues of any type with the unit. My visual examination of the unit, confirms that it is superbly built. The installation is exactly as I anticipated with no variation whatsoever from the first. All in all on a scale of one (1) to ten (10) with ten (10) being excellent I would give it a ten (10) without a doubt.

Rated 5 out of 5 by from Good generator, wifi connectivity needs work. Generator and install crew were and are great. 2 days and we were protected. 4 weeks to get the wifi connectivity fixed. Technician finally found a failed wire harness. Final steps are to get a refund for double monitoring payment. Had to send over a dozen emails and call early morning to get through to person on the phone. Do not call during normal business hours. Have been on hold for over 2 hours and they never call back when offer a call back on while on hold. Good generator. Poor monitoring connectivity process and service.
