Generac Protector 27kW 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 4 out of 5 by from Good, but gen communication to network poor we love this power back up solution. Problem was that the generator won't send status to my wifi. My wifi connects to the generator, but the generator fails to send it's status. Generac help on line is useless and provides no assistance at all. I paid for this capability, but there's no way to ensure it works and Generac fails to help.

Rated 4 out of 5 by from Still early to evaluate Took far too long. Feb to sept. Communications during this was totally lacking Once installation started the progress was very good. The crew showed me how to run it up and gave me the documentation for the Generac. They did not connect the WiFi connection. I will need to call in the morning. Overall, I am impressed with unit and look forward to using the WIFi

Rated 5 out of 5 by from Great 27 KW generator Hopefully we will never have to use the Generator but in testing and weekly runs the unit is very quiet compared to others. We have to place the unit 5 ft in air due to flood plane in Houston and the small footprint made this quite easy. Looks are very clean.

Rated 5 out of 5 by from best in the industry, only brand to have. I needed a high quality reliable generator that I could depend on. Generac has been the leader in this field. I am a master electrician and have installed many back up power systems over the last 42 years. I believe Generac systems are the best and the the easiest system to install.

Rated 4 out of 5 by from Be Specific Make sure not to make location decisions and plans with the sales people, there were too many things I wanted that weren't possible due to regulations but the sales person said yes. While we like the product it is not as initially described.
