18-150 kW Liquid-Cooled Automatic Standby Generators

18-150 kW Liquid-Cooled Automatic Standby Generators

The Generac QT Series makes standby power a sound investment for residential, commercial and light industrial applications. These revolutionary generators are exceptionally quiet, environmentally friendly and so affordable they can often pay for themselves during a single power outage in commercial and industrial applications.

Generac's exclusive Quiet-TestTM feature allows the engine to run at slower speeds during the weekly self-test, resulting in sound levels comparable to a car idling in the driveway. Natural gas operation means fewer exhaust emissions and no diesel odor. A reliable, continuous supply of natural gas eliminates refueling and there's no need for expensive double-walled diesel tanks, no fuel maintenance and no risk of environmental liability from fuel spills.

  • Quiet-Test™: Patent-pending, self-test feature makes the QT Series 50% quieter and more fuel efficient during the generator's weekly self-test cycle
  • Superior Paint: Tough, textured powder coat paint finish for unmatched durability and all weather protection
  • Clean Burning Fuel: Natural gas or LPV
  • Aluminum Enclosures: Some models come equipped with all aluminum enclosures to better withstand the elements in highly corrosive environments.
  • UL Listed: For safety and certified power ratings
