FEATURES
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.
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
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.
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.
