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.

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. Learn more about Mobile Link

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 4 out of 5 by from Very quite This is my 2nd Generac generator. The first one was air cooled and was very loud. It lasted about 3 years before it burned up. A rep from Generac came out and confirmed it could not be repaired. My current one is a Qs 38KW in the liquid version and is very quite. It has only been installed for about 3 weeks now so I can’t say much about its performance. I can say I ordered it in April and only got it installed 3 weeks ago. Long delivery time along with an elevated structural platform, city permits for natural gas, electricity and a general construction permit in a flood zone. Be prepared to spend $30plus thousand dollars by the time it is up and running. Estimated cost to run it on natural gas is around $140 per day. We live on the Gulf Coast and are subject to major storms every so often and have lost electricity several times for short periods. It gives us some comfort that when or if we are out of town the Generac will protect our household from such an outage. Thanks

Rated 5 out of 5 by from Peace if Mind We have not had to used it yet. We like the peace of mind that our last generator gave us when we lived near Houston. This is a bigger unit and the first to have limited monitoring with an app. Wish it had on and off feature.

Rated 5 out of 5 by from Love the Mobile Link App Being able to keep tabs on my generator & knowing what is happening with text notifications gives me the peace of mind whether at home or on the road. It’s a great investment & the generator has our home prepared for whatever life/Mother Nature throws our way next.

Rated 5 out of 5 by from Reliable Power This product delivers reliable power. We have recently moved from Deep South Louisiana to North Carolina. We had a total of two generator in our time in NOLA as we updated after our original one pasted the 10-year mark. During Hurrican Isaac, we were without power for 8 days. We had power within a minute of the grid going down and didn't miss a beat until power was restored on the grid. We have recently placed a generator on our property in NC and have great piece of mind that we will always have power even if grid power is not available. We used Power Source for our purchase and installation, excellent service!
