Automatic Backup Power For Large or Custom Homes
Looking to back up your entire home, or more items than usual? Consider the Protector gaseous automatic backup generator line. These units powers essential appliances and modern technologies during power outages, allowing homeowners and their families to continue living life comfortably and without interruption.

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.

The best liquid cooled engine packs more power into a smaller footprint - ideal when space is a premium.  The neutral styling, color and small footprint fits unobtrusively into landscaping. Clean burning, continuous fuel choice of natural gas to LP.

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.

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
Comes standard with all Protector Series generators. Mobile Link 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. Connect your account to an authorized service dealer for fast, friendly and convenient assistance. With Mobile Link, your generator is taken care of before the next outage.

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 38KW Generator - glad with my choice! Very satisified with the 38KW generator bought - and was amazed on how "quiet" it is when turned on (the noise level is way lower than for smaler generators).

Rated 5 out of 5 by from This generator has great features! We love this Generac generator. This unit is model RG03824ANAX. While in the test run we noticed is it a bit quieter than the one we had at our previous home. This on is liquid cooled which we were told it would be able to run longer without any problems. Our weather here we have had two instances where we were out of power for 10-12 hours. Looking forward to be ready for the winter!

Rated 5 out of 5 by from Compact and quiet running We are impressed with the size and how quiet in runs. With only what we saw at other residences, we thought our 38K generator would be much bigger and louder. And, when it arrived, we were surprised at the compact size and how quiet it runs. We do love the app and see it helping us keep up with the weekly exercise routine and maintenance. Really cool unit !

Rated 5 out of 5 by from Quiet generator Our Generac Supercenter generator is the only one that our HOA will accept due to the fact that it is very quiet.

Rated 4 out of 5 by from Missing feature The machine seems well built and the installation was smooth but there is an important feature missing. I have a Kohler generator at another location and when it exercises weekly it also takes the full load at the transfer switch and then switches back to normal mode automatically before it runs its cool down cycle. This is a valuable feature as it really tests the whole system weekly, but the Generac cannot perform that and requires a manual override of the transfer switch so it cannot run an acutal full system test. Very disappointed!

Rated 4 out of 5 by from Core product great Mobile Link not so great This is my second Generator purchase from Generac. For both generators I purchased the Mobile Link option. My experience with the Generators was exceptional. When it comes to Mobile Link the product never seems to reach maturity. There are now 2 Mobile Link products and during setup no one in support seemed clear on which I should be using. They were also unclear on which mobile link options came with my generator. The support team was convinced I did not have the WiFi option but I did. The rep that spent time with me stuck with it to get me going but it was clear there is a lack of training on the product, unclear information on generator configuration and a number of bugs in the application. I received a message that my account issue had been resolved but no other information. As of the writing of this review all of my issues except mis-reported maintenance history have been resolved but it seems my ticket was closed for some other unknown issue.
