Spec Sheet

The QT02224ANAX includes:

  • 1x Generac QT02224 22,000 Watt QuietSource Standby Generator


  • 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. Packs more power into a smaller footprint than air-cooled models.
  • 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.
  • Clean burning, continuous fuel choice of LP or natural gas.
  • Quiet-Test mode - All standby generators run a weekly test to ensure the system is running properly. Thanks to Quiet-Test, your QuietSource Series standby generator runs its self-test at a lower, quieter RPM than standard operation.
  • 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.
  • Neutral styling, color and small footprint fits unobtrusively into landscaping.
