Generac Protector 38kW QS Standby Generator

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.

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
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 Large Residential Generator With having two EV's in the garage, I needed larger than the typical generator. Plus I truly like the continuous optional option with a water cooled engine. All this said, I am truly pleased with both the unit and the installation.

Rated 4 out of 5 by from Powers My Whole House I like that this unit comes on as necessary and powers the whole house wiithout me having to worry about what to shut off and what to run. Only problem is a small oil leak under the engine. Hopefully that can be fixed without too much hassle. Waiting for return call from installer.

Rated 5 out of 5 by from Nice features, quality installation, professional install team. I was pleased with the professionalism of the install team, as well as with the appearance of the genset and the accessory utility work that accompanied the install (gas, electricity, foundation). The job was completed satisfactorily in 1 day, and we are comforted to know that we are now "power secure" as we enter the peak of the hurricane season. The unit will fully cover our standby generator needs and expectations.

Rated 5 out of 5 by from Good Generator I can't say enough about the full package of installation. Very professional and complete. This generator is amazingly quiet and so far has worked flawlessly. It starts up and switches on in just few short seconds and so far has been very reliable. It's easy to maintain and looks very good and has a small footprint in my yard. Looking forward to now being protected from any further problems with the power grid in Oklahoma.

Rated 5 out of 5 by from So far so good. Look forward to test run. About to start up and test 38 kw in a couple days. Installation and electrical set up has been excellent.

Rated 5 out of 5 by from Well built! Great machine! Quality design and build! Engine protective interlocks seem adequate, but I wish that that the temperatures, pressures, and levels were viewable over the phone app. All positive comments for the device. This Generac replaced a 2006 Generac 40KW that had been damaged by a lightning surge. My negative comment is that it took 4.5 months to ship...I suppose COVID had something to do with that issue.

Rated 5 out of 5 by from Works. Power went down a couple of days after installation, generator came on and shut down when power came back on.
