¡ 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

systems.

¡ 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.
