FEATURES
Innovative Design & Prototype Testing
Innovative Design & Prototype Testing are key components of GENERAC'S success in "IMPROVING POWER BY DESIGN." Total commitment to component testing, reliability testing, environmental testing, destruction and life testing, plus testing to applicable CSA, NEMA, EGSA, and other standards, allows you to choose GENERAC POWER SYSTEMS with the confidence that these systems will provide superior performance.
True Power® Electrical Technology
Superior harmonics and sine wave form produce less than 5% Total Harmonic Distortion for utility quality power. This allows confident operation of sensitive electronic equipment and micro-chip based appliances, such as variable speed HVAC systems.
Solid-State, Frequency Compensated Voltage Regulation
This state-of-the-art power maximizing regulation system is standard on all Generac models. It provides optimized FAST RESPONSE to changing load conditions and MAXIMUM MOTOR STARTING CAPABILITY by electronically torque-matching the surge loads to the engine. Digital voltage regulation at ±1%.
Single Source Service Response
Generac's extensive dealer network provides parts and service know-how for the entire unit, from the engine to the smallest electronic component.
Generac Transfer Switches
Long life and reliability are synonymous with GENERAC POWER SYSTEMS. The GENERAC product line includes its own transfer systems and controls for total system compatibility.
