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.
