Features & Benefits
Up to whole house protection with the 200-amp, NEMA 3R (aluminum outdoor enclosure) smart switch.
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 generators and engines are engineered and built in the USA*.
*Assembled in the USA using domestic and foreign parts
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.
Our RhinoCoat™ powder-coated finish helps make corrosion-resistant aluminum perfect for all weather conditions.
Mobile Link™ Remote Monitoring allows you to monitor the status of your generator from anywhere in the world using a smartphone, tablet, or PC. Easily access information, such as the current operating status and the generator’s maintenance schedule. Connect your account to your authorized service dealer for fast, friendly and convenient assistance. Click to lean more. (sold separately)
