FEATURES

INNOVATIVE ENGINE DESIGN & RIGOROUS TESTING
are at the heart of Generac’ssuccess in providing the most reliable generators possible. Generac’s G-Force enginelineup offers added peace of mind and reliability for when you need it the most. TheG-Force series engines are purpose built and designed to handle the rigors ofextended 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 onall Generac models. It provides optimized FAST RESPONSE to changingload conditions and MAXIMUM MOTOR STARTING CAPABILITY byelectronically torque-matching the surge loads to the engine. Digitalvoltage regulation at ±1%.

TRUE POWER™ ELECTRICAL TECHNOLOGY:

Superior harmonics and sine waveform produce less than 5% Total Harmonic Distortion for utility quality power. This allowsconfident operation of sensitive electronic equipment and micro-chip based appliances,such as variable speed HVAC systems.

SINGLE SOURCE SERVICE RESPONSE

from Generac’s extensive dealernetwork provides parts and service know-how for the entire unit, from theengine 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 aresynonymous with GENERAC POWER SYSTEMS. One reason for thisconfidence is that the GENERAC product line includes its own transfersystems and controls for total system compatibility.

MOBILE LINK™ REMOTE MONITORING: FREE

with every Guardian Series Homestandby generator. Allows you to monitor the status of your generator from anywhere in theworld using a smartphone, tablet, or PC. Easily access information such as the currentoperating status and maintenance alerts. Connect your account to your authorized servicedealer for fast, friendly and proactive service. With Mobile Link, you are taken care of beforethe next power outage.

TMNote: 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.

features and benefits

Engine

Generac G-Force design Maximizes engine “breathing” for increased fuel efficiency. Plateau honed cylinder walls and plasma molyrings helps the engine run cooler, reducing oil consumption 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.

Generator

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 regulatio n Regulates the output voltage to ±1% prevents damaging voltage spikes.
UL 2200 listed: For your safety.

Transfer Switch (if applicable)

Fully automatic: Transfers your vital electrical loads to the energized source of power.
NEMA 3R: Can be installed inside or outside for maximum flexibility.
Remote mounting: Mounts near your existing distribution panel for simple, low-cost installation.

Evolution™ Controls

Auto/Manual/Off illuminated buttons: Selects the operating mode and provides easy, at-a-glance status indication in any condition.
Two-line LCD multilingual display: 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, set points 65% dropout, 80% pick-up, of standard voltage.
Generator voltage sensing: Constantly monitors generator voltage to ensure 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 offive (5) seconds by a qualified dealer.
Engine warm-up Ensures engine is ready to assume the load, set point approximately 5 seconds.
Engine cool-down Allows engine to cool prior to shutdown, set point 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.

Unit

SAE weather protective enclosure: Sound attenuated enclosures ensure quiet operation and protection against mother nature, withstanding winds up to 150 mph. Hinged key locking roof panel for security. Lift-out front for easy access to all routine maintenance items. Electrostatically applied textured epoxy paint for added durability.
Enclosed critical grade muffler: Quiet, critical grade muffler is mounted inside the unit to prevent injuries.
Small, compact, attractive: Makes for an easy, eye appealing installation, as close as 18″ (457 mm) away from a building.16/20/22 kW.

Installation System

1 ft (305 mm) flexible fuel line connector: Absorbs any generator vibration when connected to rigid pipe.
Direct-to-dirt composite mounting pad Complex lattice design prevents settling or sinking of the generator system.
Integral sediment trap Prevents particles and moisture from entering the fuel regulator and engine, prolonging engine life.

Remote Monitoring

Ability to view generator status: Monitor your generator via your smartphone, tablet, or computer at any time via the Mobile Link application for complete peace of mind
Ability to view generator Exercise/Run and Total Hours: Review the generator’s complete protection profile for exercise hours and total hours
Ability to view generator maintenance information: Provides maintenance information for your specific model generator when scheduled maintenance is due
Monthly report with previous month’s activity. Detailed monthly reports provide historical generator information
Ability to view generator battery information: Built in battery diagnostics displaying current state of the battery.
Weather information: Provides detailed local ambient weather conditions for generator location.
