¡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.
¡ ES :Offers an extreme value for those who desire automatic backup power at
the most affordable price.
¡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.
¡SINGLE SOURCE SERVICE RESPONSE from Generac’s 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.

**Sound levels are taken from the front of the generator. Sound levels taken from other sides of the generator may be higher depending on installation parameters. 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/megajoule content, ambient temperature, altitude, engine power and condition, etc. Maximum power decreases about 3.5 percent for
each 1,000 feet (304.8 meters) above sea level; and also will decrease about 1 percent for each 6° C (10° F) above 16° C (60°F).
