These units power 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 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. 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 5 out of 5 by from Well designed The generator was installed today and it is running beautifully. The house has been running on it for 2 hours now while we were waiting on the lineman to reconnect power to the house i can barely hear the generator and the house acts like it is on the main power.

Rated 4 out of 5 by from The product is providing the backup power desired. While we are still in our initial break in period, the unit is providing the backup power supply as desired. The power level is sufficient and the transfer switch operates as intended. The unit is reasonably attractive and sound level is acceptable. The installing contractor has thus far performed the installation very well, but I am still awaiting the wiring harness to activate the wi-fi/app connection. This was not included with the unit when shipped. Please forward this at your earliest convenience so that the installation can be completed.

Rated 5 out of 5 by from 22KW Generac Hightower Electrical Contractor just completed installation of my Generac generator. They were very professional, answered all my questions and went out of their way to make sure I was completely satisfied. If you get a Generac generator I would strongly recommend Hightower do the installation. You will be very pleased!

Rated 5 out of 5 by from Best generator and AMAZING customer service! My family and I recently moved down to Florida, we were very aware of hurricanes that happen here, and one of our first decisions we had was to get a back up generator. As we run a family business out of our home, not having power for even an hour can really set us back tremendously. The people at Generator Super Center could not have been any better. They took all the stress out of everything. They communicated and explain all their products and how they would get it installed to be fully functional, but also make everything look great! They even took it on their behalf to contact the gas company and orchestrate the job! I would highly recommend ANYONE looking to get a generator to reach out to them! It’s better to be safe than sorry in this type of situation! Plus it can save you TONS of money down the road. I know my wife, kids and I will be safe and happy with the generator we got!

Rated 4 out of 5 by from Just got it online So i can't vouch for it's durability, appears the be well made. From what I've been told, Generac is super picky about warranty issues, so only have certified techs work on it if you can afford that.
