Generac Synergy 20KW Generator

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.

Evolution™ Controller. The next generation of intuitive controllers, the Evolution controller features a multilingual, two-line LCD text display with color-coded backlit buttons.

Automatic Voltage Regulator (AVR). 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.

Specialized Alternator. 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.

Resonator. 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.

Quiet-Test™. Thanks to Quiet-Test, your Synergy home backup generator runs its weekly self-test at a lower RPM.

Generac OHVI® Engine. 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.

All-Weather Aluminum Enclosure. 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.
