  • Premium-grade standby generator is compatible with small commercial buildings with 120/240V 3 phase service
  • Provides 22 kilowatts when using either liquid propane or natural gas
  • Generac 4-line liquid-cooled engine provides ample power at half the speed (1800 vs 3600 RPM)
  • Aluminum enclosure features corrosion resistant material for protection against salty air
  • Operates at 61 decibels (same level as an idling car) at 23 feet, and weekly tests are quiet as well

No beating around the bush, starting and keeping a small business afloat is pretty difficult. When volatile weather conditions come around, losing power is just one of many factors that can derail your forward progress. Luckily, Generac has a great standby generator that will fit your needs, the QT02224JNAX. This machine provides 22 kilowatts of power when you need it most, and it can run on liquid propane or natural gas. It is equipped with a 4-line liquid-cooled engine that provides all this power with half as much speed as the competition (1800 RPM vs 3600 RPM). If your building is near the shoreline, you also have to deal with the damaging effects of salt air. Generac has a solution for that as well; the aluminum enclosure keeps all weather conditions out, and it also has corrosion-resistant material to foil salt air's attempts at sabotage. You won't need to wear earplugs with the QT02224JNAX; its sound output is on the same level as an idling car (61 decibels). This premium-grade standby generator will help you weather many storms for years to come, giving you one less thing to worry about. Tools Plus is the best place to purchase standby generators from Generac, as well as a multitude of other power tools, hand tools, metal and woodworking machinery.

The QT02224JNAX includes:

  • 1x Generac QuietSource Standby Generator (CARB Compliant)


  • 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.
