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.

Rated 5 out of 5 by from Backup generator installed today! The unit is attractive from the outside. The unit seems very well designed and laid out inside the cabinet. The motor is quieter than my Honda motorhome generator. The unit starts up quickly, transfers power and delivers clean power. The lights don't pulse or dim; the motor doesn't bog down when my well pump or larger power consuming appliances come on. Setup on propane or NG is the way to go. Great job Generac!

Rated 5 out of 5 by from This Generator is awesome I really like this unit, it is attractive,quiet,and easy to program. I just got it installed yesterday and everything went well and it started right up. I feel much better knowing the next time the power goes out I don't have to worry about my basement flooding because my sump pump will always have power whether I'm home or not.

Rated 5 out of 5 by from Very good looking unit and insaller did a great job. This unit replaced a portable generator that we had for a number of years. The installation was done very well and we look forward to the convenience of having the Generac automatically restore power when it goes out.

Rated 5 out of 5 by from Reliable, quiet function This unit replaced a 20 year old stand by generator by a different manufacturer. In comparison, obviously this was a huge improvement. We are impressed by the appearance, quiet function, and reliability of Generac. We are able to run our outdoor wood boiler furnace in winter and AC unit in summer without concern.

Rated 5 out of 5 by from Everything i asked for The General 11kw is the perfect size for my family. I was amazed at the number of circuit breakers for this unit. The majority of my home will be with power. I am thankful I went with General. When the unit was on, it runs quite smoothly and softly. Not loud and noisy like others I've seen. Thanks Generac

Rated 4 out of 5 by from So Far So Good The product seems to work well. It comes on as scheduled each week for it's check-up. The Generac did come on 3 quick times during a snow storm when the power went out for a few minutes here and there. Only have had the unit since Oct. 2016, went through a New England Winter, but have not even had the unit for a year Would just tell prospective customers to be careful with whom they do business as the Electrical Contractor. Would not recommend the one we used.

Rated 5 out of 5 by from Piece of Mind The product installers spent no more than 6 hours installing this. No drywall needed to be fixed, very clean installation. 16 circuits is more than enough to cover the basics and then some niceties like a couple bedrooms, baths, washer/ dryer.

Rated 5 out of 5 by from mental comfort this is a mental comfort knowing the hole house is included in power option when there is a power failure it is quiet unobtrusive recommended without reservation
