Features and Benefits

Engine

• Generac G- Force design: Maximizes engine “breathing” for increased fuel efficiency. Plateau honed cylinder walls and plasma moly rings 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 regulation: Regulates the output voltage to ±1% prevents damaging voltage spikes.
• True Power Technology: Less than 5% total harmonic distortion (THD).

Evolution™ Controls

• Auto/Manual/Off illuminated buttons: Selects the operating mode and provides easy, at-a-glance status indication in any condition.
• 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.
• 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: Ensures 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 seven day 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 50 Hz frequency.
• Wi-Fi Connectivity

Unit

• Weather protective Aluminium Enclosure: Sound attenuated enclosures ensure quiet operation and protection against mother nature, withstanding winds up to 240km/h. 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 muffler: Quiet, critical grade muffler is mounted inside the unit to prevent injuries.
• Small, compact, attractive: Makes for an easy, eye appealing installation.

Installation System

• 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.
