FEATURES
¡INNOVATIVE DESIGN & PROTOTYPE TESTING are key components
of GENERAC’S success in “IMPROVING POWER BY DESIGN.” But it
doesn’t stop there. 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.
¡TEST CRITERIA:
PROTOTYPE TESTED NEMA MG1-22 EVALUATION
SYSTEM TORSIONAL TESTED MOTOR STARTING ABILITY
¡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 from 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. One reason for this
confidence is that the GENERAC product line includes its own transfer
systems and controls for total system compatibility.

•Generac (OHVI) Design
•“Spiny-lok” cast iron cylinder walls
•Electronic ignition/spark advance
•Full pressure lubrication system
•Low oil pressure shutdown system
•High temperature shutdown
Maximizes engine “breathing” for increased fuel efficiency. Plateau honed cylinder walls and plasma
moly rings helps the engine run cooler, reducing oil consumption resulting in longer engine life.
Rigid construction and added durability provide long engine life.
These features combine to assure smooth, quick starting every time.
Pressurized lubrication to all vital bearings means better performance, less maintenance and longer
engine life. Now featuring a 2 year/200 hour oil change interval.
Superior shutdown protection prevents catastrophic engine damage due to low oil.
Prevents damage due to overheating.

Rating definitions - Standby: Applicable for supplying emergency power for the duration of the utility power outage. No overload capability is available for this rating. (All ratings in accordance with
BS5514, ISO3046 and DIN6271). * Maximum wattage and current are subject to and limited by such factors as fuel Btu content, ambient temperature, altitude, engine power and condition, etc. Maximum
power decreases about 3.5 percent for each 1,000 feet above sea level; and also will decrease about 1 percent for each 12° C (10° F) above 15.5° C (60°F). Sound output ratings from certain points on the
generator subject to change based on installation parameters.
