INNOVATIVE ENGINE DESIGN & RIGOROUS TESTING are at the heart of Generac’s

success in providing the most reliable generators possible. Generac’s G-Force engine

lineup offers added peace of mind and reliability for when you need it 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 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%.



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 smallest 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 includes its own transfer

systems and controls for total system compatibility.



MOBILE LINK™ REMOTE MONITORING: FREE with every Guardian Series Home

standby generator. Allows you to monitor the status of your generator from anywhere in the

world using a smartphone, tablet, or PC. Easily access information such as the current

operating status and maintenance alerts. Connect your account to your authorized service

dealer for fast, friendly and proactive service. With Mobile Link, you are taken care of before

the next power outage.

Note: CUL certification only applies to unbundled units and units packaged with

limited circuit switches. Units packaged with the Smart Switch are UL certified in

the USA only.
