Protector 22 kVA - 50 Hz Model #RG02224MNAX



Keep your power and the peace with this 22kVA 50Hz generator. Packing a lot of power into a smaller footprint with less noise, ideal applications include larger homes, gas stations, convenience stores and other small businesses.

  • Powerful low-speed, liquid cooled engine is engineered to run at only 1500 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 Evolution™ Controller: 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 for a weekly self-test. 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.
  • Neutral styling, color and small footprint fits unobtrusively into landscaping.
