FEATURES
INNOVATIVE ENGINE DESIGN & RIGOROUS TESTING are at the heart of Gen-
erac’s success in providing the most reliable generators possible. Generac’s GForce engine lineup offers added peace of mind and reliability for when it’s needed
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.

MOBILE LINK
generators, Mobile Link Wi-Fi allows users to monitor generator status from anywhere in the world using a smartphone, tablet, or PC. Easily access information such
as the current operating status and maintenance alerts. Users can connect an
account to an authorized service dealer for fast, friendly, and proactive service. With
Mobile Link, users are taken care of before the next power outage.
CONNECTIVITY: FREE with select Guardian Series Home standby
EMA MG1-22 EVALUATION
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 is offered with its own transfer systems and controls for total system
compatibility.
PWRVIEW™ TRANSFER SWITCH: The Generac PWRview Automatic Transfer
Switch integrates the PWRview energy monitor to provide real-time energy consumption data that can help lower a home’s electricity bill. Using a convenient
mobile app, homeowners can access energy usage and alert information while under
utility power or generator power. The PWRview energy monitor is a simple to use and
low cost tool which helps save money over the life of the generator. Included with
model G007210-0.

Generator
Transfer Switch (if applicable)
Generac G-Force design Maximizes engine “breathing” for increased fuel efficiency. Plateau honed cylinder walls and plasma moly
rings help the engine run cooler, reducing oil consumption and resulting in longer engine life.
“Spiny-lok” cast iron cylinder walls Rigid construction and added durability provide long engine life.
Electronic ignition/spark advance These features combine to assure smooth, quick starting every time.
Full pressure lubrication system Pressurized lubrication to all vital bearings means better performance, less maintenance, and longer engine
life. Now featuring up to a 2 year/200 hour oil change interval.
Low oil pressure shutdown system Shutdown protection prevents catastrophic engine damage due to low oil.
High temperature shutdown Prevents damage due to overheating.
Revolving field Allows for a smaller, light weight unit that operates 25% more efficiently than a revolving armature generator.
Skewed stator Produces a smooth output waveform for compatibility with electronic equipment.
Displaced phase excitation Maximizes motor starting capability.
Automatic voltage regulation Regulating output voltage to ±1% prevents damaging voltage spikes.
UL 2200 listed For your safety.
Fully automatic Transfers vital electrical loads to the energized source of power.
NEMA 3R Can be installed inside or outside for maximum flexibility.
Integrated load management technology Capability to manage additional loads for efficient power management.
Remote mounting Mounts near an existing distribution panel for simple, low-cost installation.
PWRview Transfer Switch (if applicable)
PWRview energy monitor Energy usage at-a-glance.
Ability to view real-time energy consumption data Better understand the home’s energy profile.
PWRview mobile app Access daily energy intelligence and insights.
Evolution™ Controls
AUTO/MANUAL/OFF illuminated buttons Selects the operating mode and provides easy, at-a-glance status indication in any condition.
Two-line multilingual LCD Provides homeowners easily visible logs of history, maintenance, and events up to 50 occurrences.
Sealed, raised buttons Smooth, weather-resistant user interface for programming and operations.
Utility voltage sensing Constantly monitors utility voltage, setpoints 65% dropout, 80% pick-up, of standard voltage.
Generator voltage sensing Constantly monitors generator voltage to verify the cleanest power delivered to the home.
Utility interrupt delay Prevents nuisance start-ups of the engine, adjustable 2-1500 seconds from the factory default setting of 5
seconds by a qualified dealer.
Engine warm-up Verifies engine is ready to assume the load, setpoint approximately 5 seconds.
Engine cool-down Allows engine to cool prior to shutdown, setpoint approximately 1 minute.
Programmable exercise Operates engine to prevent oil seal drying and damage between power outages by running the generator for
5 minutes every other week. Also offers a selectable setting for weekly or monthly operation providing
flexibility and potentially lower fuel costs to the owner.
Smart battery charger Delivers charge to the battery only when needed at varying rates depending on outdoor air temperature.
Compatible with lead acid and AGM-style batteries.
Main line circuit breaker Protects generator from overload.
Electronic governor Maintains constant 60 Hz frequency.
