FEATURES

  • True Power™ Technology delivers best-in-class power quality with less than 5 percent total harmonic distortion for clean, smooth operation of sensitive electronics and appliances.
  • Generac generators and engines are engineered and assembled in the USA*
  • Generac’s Evolution™ Controller features a multilingual LCD display that allows users to monitor battery status and track maintenance intervals to ensure your generator is always in top operating condition.
  • Unlike competitive units that run at a constant speed, patented G-Flex technology allows the Generac Synergy to run at lower speeds when household electrical demand is light. That means significantly quieter operation at normal capacity, less fuel consumption when you need less electricity, and cleaner power than competitive air-cooled home standby generators.
  • Generac's G-Force Engine is a purpose-built, pressure-lubricated engine capable of handling the rigors of generator use, resulting in power that’s more reliable and requires less routine maintenance than any competitive engine.
  • Quiet-Test™ Self-Test Mode runs at a lower RPM for a five or twelve minute test, making generators significantly quieter than other brands while consuming less fuel.
  • 24/7/365 Customer Support Team standing by all day, every day from our headquarters in Wisconsin to answer any questions you might have.
  • Our RhinoCoat™ powder-coated finish helps make corrosion-resistant aluminum perfect for all weather conditions

"We absolutely LOVE this gazebo! It is a great size and great quality! We used to have another gazebo with a canvas top, which we had to replace every year because it deteriorated. We decided to get a metal roof and it looks even better than we thought it would! The screens are great quality too!"
