Product Details

Generac Guardian 16kW With Whole House Switch - 6462

Provides essential circuit power protection for your home, ensuring the necessities remain powered during an outage or up to whole house coverage when paired with one of Generac's load- shedding switches.


  • 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 Smart Switch, re-engineered connection points, and composite mounting pad that eliminates the need for a poured concrete base (unless specified by local codes).
  • Rated for Operation in Areas with Low Natural Gas Pressure
    In areas with low natural gas pressure, the Guardian Series 20kW 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 conditions. 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.
  • Quiet-Test™ Mode
    All standby generators run a weekly test to ensure the system is running properly. Thanks to Quiet-Test, your Guardian Series home standby generator runs its self-test at a lower, quieter RPM than standard operation, and can be programmed to run 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.
  • 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


  • Generac (OHVI) design
    Maximizes engine "breathing" for increased fuel efficiency. Plateau honed cylinder walls and plasma moly rings helps the engine run cooler, reducing oil consumption resulting in longer engine life.
  • Quiet-Test™
    Greatly reduces sound output and fuel consumption during bi-weekly exercise, compared to other brands.
  • "Spiny-lok" cast iron cylinder walls
    Rigid construction and added durability provide long engine life.
