Product Details

Generac Guardian 11kW With Whole House Switch Generator - 6438

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.

Features:

  • Generac OHVI® Engine
    Your Guardian Series generator might have to get you through days—or weeks—without utility power. Its 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 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
    With an intelligent pre-wired transfer 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.
  • 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.
  • 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.
  • 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.

A generous neighbor helped us get through multi-day power outages two winters in a row by loaning us an old, cranky portable generator. We did not have option of finding other shelter because my wife's poor health and dietary restrictions keep her homebound. I took the second outage as a clear sign we needed our own generator. I chose a Generac Guardian and an automatic transfer switch for its simplicity and the ability to power our whole house (not just the boiler, freezer and some lights on extension cords). Although there were no power outages during the past two winters, I still feel the Guardian is best home improvement we've ever made because it gives us the security of knowing we'll get through upcoming winters (and other events). This week's automatic Guardian 12-minute test run prompted me to write this review. -- Ward in rural Massachusetts

Had this product installed in August of 2013 and have had constant problems: 1) Oil leak and battery acid leak upon initial installation. Generac agreed to replace. 2) One month later new generator installed and fuse was blown upon installation 3) One week after new generator installed the transfer switch broke. All power to my house turned off 4) One week later I had a problem with the controller which shut down the unit. I have had the unit installed and in service for probably less than four weeks and have had to deal with five different part failures. Generac has been good about dealing with the problems but the overiding fact is that this product is very unreliable. For a product that is used in an emergency, this should be unacceptable. I would strongly advise anyone thinking of purchasing to look elsewhere.

Comments about Generac Guardian 11kW With Whole House Switch Generator:

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

Comments about Generac Guardian 11kW With Whole House Switch Generator:

It runs quiet just as advertised. I live on an island that has daily power interruptions. During power interruptions it starts and powers up in 30 seconds. Its durable case keeps the generator dry and helps muffle the sound. It performs for hours like a 'Muscle Car' coming off the line. The auto-transfer switch works smooth and accurate.

Living in the country is even more enjoyable now that I have a Generac generator. No worries about power-outages or operating controls. It runs itself seamlessly. In addition, the design is pleasing to the eye. I am very happy with this dependable product.
