Most generator engines have to run at a constant speed to produce electricity, regardless of the electrical demand. Generac’s patented G-Flex technology changes that by allowing the engine on the Generac Synergy to run only as fast as necessary to meet the electric load demand. Thus, the Generac Synergy matches generator output to actual power needs. The end result is a much quieter, more fuel-efficient generator with exceptionally clean power output.
Patented G-Flex technology allows the Generac Synergy home standby generator to vary its speed based upon electrical demand. It will run slower—and quieter—when you use less electricity. And during its weekly exercise, you’ll hear only about as much sound as if you were riding in a luxury car. The Synergy also consumes less fuel when electricity demand is light, saving you money. And G-Flex technology delivers electricity with less than 2.0% total harmonic distortion (THD)—lower than IEEE standards for utility power— to properly power modern electronics and sensitive appliances.
The next generation of intuitive controllers, the Evolution controller features a multilingual, two-line LCD text display with color-coded backlit buttons.
The brains behind the G-Flex technology, the AVR monitors electrical demand and reduces engine speed accordingly. It also keeps tabs on alternator output frequency at lower engine speeds. Then it electronically manipulates alternator output to achieve 60 Hz electrical power. In doing so, it produces exceptionally clean power—less than 2.0% THD.
The rotor has three windings instead of the normal two. They are electronically controlled by the AVR to ensure 60 Hz output, even at a lower speeds.
The unique resonator is specifically designed to improve sound quality and minimize overall sound levels. The result is a lower tone that, when combined with the generator’s quieter operation, is more pleasing to the ear. During its weekly exercise, the Generac Synergy is about as quiet as riding in a luxury automobile.
At normal capacity, the Generac Synergy isn’t just quieter—it’s more pleasing to the ear. Compare it to the sound of a portable generator or a standard Guardian® Series home standby system, and we think you’ll agree.
A portable generator has an open frame, with only a muffler to reduce engine sound.
With its sound-deadening enclosure, the 20 kW Guardian Series runs much quieter than a portable generator.
More sound-deadening foam, patented G-Flex™ technology, and a special resonator makes the Synergy significantly quieter than many competitive gensets at normal capacity.
Mobile Link is the cellular remote monitoring system from Generac that lets you check on your generator’s status even when you are away using your computer, tablet or smartphone.
Thanks to Quiet-Test, your Synergy home backup generator runs its weekly self-test at a lower RPM.
Your Synergy home backup generator might have to get you through days—or weeks—without utility power. Its OHVI engine, specifically designed for generator use, provides the reliability to power through the most severe outages.
Our durable powder-coat finish helps make the sturdy, aluminum enclosure perfect for all weather conditions. It’s also able to withstand 150 mph winds.
As the leader in the standby generator market, Generac continues to deliver innovation. Our new Generac Synergy 20kW variable speed backup generator, the industry’s first variable speed home generator available, provides home owners with the highest level of technology available in the market today.
