FEATURES
 INNOVATIVE ENGINE DESIGN & RIGOROUS TESTING are at the heart of Gen-
erac’s success in providing the most reliable generators possible. Generac’s G-
Force engine lineup offers added peace of mind and reliability for when it’s needed
the most. The G-Force series engines are purpose built and designed to handle the
rigors of extended run times in high temperatures and extreme operating conditions.
 SOLID-STATE, FREQUENCY COMPENSATED VOLTAGE REGULATION: This
state-of-the-art power maximizing regulation system is standard on all Generac mod-
els. It provides optimized FAST RESPONSE to changing load conditions and MAXI-
MUM MOTOR STARTING CAPABILITY by electronically torque-matching the surge
loads to the engine. Digital voltage regulation at ±1%.
 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.
 SINGLE SOURCE SERVICE RESPONSE from Generac’s extensive dealer network
provides parts and service know-how for the entire unit, from the engine to the small-
est electronic component.
 TEST CRITERIA:
 PROTOTYPE TESTED  NEMA MG1-22 EVALUATION
 SYSTEM TORSIONAL TESTED  MOTOR STARTING ABILITY
 GENERAC TRANSFER SWITCHES: Long life and reliability are synonymous with
GENERAC POWER SYSTEMS. One reason for this confidence is that the GENERAC
product line is offered with its own transfer systems and controls for total system
compatibility.
