Generac Power Systems 6720 Details and Specifications

Generac Guardian 11kW Home Standby Generator NG/LP Single Phase Generator Only with Aluminum Enclosure | 6720

Features & Benefits:

Genreac 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.

Evolution™ Controller:  The next generation of intuitive controllers featurng 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 codees), the Guardian Series 11kW generator is easy to install. (Transfer Switch is sold separately)

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

All-Weather Aluminum Enclosure:  Our durable powder-coat finish helps make the sturdy, all-weather aluminum enclosure corrosion resistant, making it ideal for coastal, salt-air climates.  It's also able to withstand 150 mph winds.

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

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.

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 11kW self-test runs for only twelve minutes.  Choose your schedule - weekly, bi-weekly or monthly.

Mobile Link™ Compatible:  Take advantage of Genearc'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.

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.
