Premium features are standard for the ultimate standby generator. Thanks to the low-speed engine, it’s so quiet you’ll forget you own a generator until you need it. Ideal for large residential and small to medium commercial applications.

  • Powerful low-speed, liquid cooled engine is engineered to run at only 1800 rpm for a substantially quieter generator, consuming less fuel and giving both the engine and alternator a longer life.
  • Generac’s Nexus™ Controller is the most comprehensive available. The dual line, tri-lingual LCD display allows for easy monitoring and management of generator functions.
  • Quiet-Test™ mode for a weekly self-test that runs quieter than other brands. Patented, programmable feature validates proper operation. Runs at lower RPM for reduced noise, less fuel consumption and fewer emissions.
  • Standard aluminum, all-weather enclosure provides the ultimate protection from the elements. Aluminum’s corrosion resistance prolongs the life of your generator and is recommended for salt-air, coastal locations.
  • Clean burning, continuous fuel choice of LP or natural gas.
  • Neutral styling, color and small footprint fits unobtrusively into landscaping.
