Guardian 11 kW Generator Features and Benefits

Provides essential circuit power protection for your home, ensuring the necessities remain powered during an outage. Has the ability to backup a 3-ton air conditioner, well pump or water heater, and the main rooms of your house.

Guardian 11 kW Generator <strong>Features and Benefits</strong>

Generac OHVI® Engine
Your Guardian Series generator might have to get you through days—or weeks—without utility power. Generac’s OHVI® engine, specifically designed for generator use, provides the reliability to power through the most severe outages.

True Power™ Technology
Best-in-class power quality with less than 5% total harmonic distortion means clean, smooth operation of your sensitive electronics and appliances.

Evolution™ Controller
The next generation of intuitive controllers featuring a multilingual, two-line LCD text display with color-coded, backlit buttons.

Certified for 18" Installation to the Home
Third-party certified to NFPA standards to be installed as close as 18” from the home’s exterior wall, provided it is located away from doors, windows, and fresh-air intakes, and unless otherwise directed by local codes.

Easy Installation
When combined with a pre-wired transfer switch or Smart Switch, re-engineered connection points, and composite mounting pad that eliminates the need for a poured concrete base (unless specified by local codes), the Guardian Series 11 kW generator is easy to install.

Rated for Operation in Areas with Low Natural Gas Pressure
In areas with low natural gas pressure, the Guardian Series 11 kW generator can operate on natural gas pressures of only 3.5” of water column.

All-Weather Steel Enclosure
Our durable powder-coat finish helps make the sturdy, Galvanneal steel enclosure perfect for all weather confitions. It’s also able to withstand 150 mph winds. Optional aluminum available, recommended for salt-air locations.

Tool-less Fuel Conversion
Switch between natural gas and LP fuel in the field in a few seconds, without the need for any tools.

Quick, Quiet Exercise Test
Standby generators require a short run-time periodically, known as exercise, to test and ensure the system is functioning properly and ready for an emergency. The Guardian 11 kW self-test runs for only twelve minutes. Choose your schedule - weekly, bi-weekly or monthly.

Mobile Link™ Compatible
Take advantage of Generac’s Mobile Link cellular remote monitoring system and check on your generator’s status using your computer, tablet or smartphone, even when you are away. Sold separately.

Non-cellular remote monitoring options are also available for generator monitoring from inside the home.

24/7/365 Customer Support
Power outages don’t always occur during normal working hours. That’s why Generac’s customer care call center—right here in Wisconsin—provides support any time of day or night, all year long. Generac is standing by 24/7, every minute of every day, to answer your questions.

5-year Limited Warranty

Home Generator Buyer's Guide

Included with This Generator Bundle

Gain up to whole-house coverage through smart power management. If it is unlikely you will turn on every appliance at the same time (most people don’t), a smaller generator paired with a Generac Smart power management transfer switch provides whole-house coverage through a managed power solution. The process is simple - non-essential circuits are shed when the generator approaches maximum capacity to eliminate overload, then are cycled back on when essential circuits are satisfied. Give yourself a little more than just the basics without a substantial increase in your investment.

Rated 4 out of 5 by from very satisfied Great for the country where power outages are a regular happening and restoration of power can be sporadic. It will be great when Canada gets better representation for the product. Most of the setup and installation had to be coordinated by myself. -Noel

Rated 5 out of 5 by from Looks good. Just waiting for the weather to get bad and the power to go out so I can see how this unit performs.

Rated 5 out of 5 by from Excellent Product! This unit hasn't been used for an emergency yet, but it starts right up when doing it's weekly self check. I have no doubt that when needed, this generator will work as advertised. I am very pleased with my purchase. And I must say, it does give my family peace of mind that we will have power in event of a power outage.
