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.
SINGLE SOURCE SERVICE RESPONSE
from Generacs dealer
network provides parts and service know-how for the entire unit, from
the engine to the smallest electronic component.You are never on your
own when you own a GENERAC POWER SYSTEM.
GENERAC TRANSFER SWITCHES,
SWITCHGEAR AND
ACCESSORIES.
Long life and reliability is synonymous with
GENERAC POWER SYSTEMS. One reason for this confidence is that
the GENERAC product line includes its own transfer systems,
accessories, switchgear and controls for total system compatibility.

Composite Mounting Pad (Std)
Maximizes engine breathing for increased fuel efficiency. Cylinder walls run cooler, reducing
oil consumption. Because heat is the primary cause of engine wear, the OHVI has a significantly
longer life than competitive engines.
Rigid construction and added durability provide long engine life.
These features combine to assure smooth, quick starting every time.
Superior lubrication to all vital bearings means better performance, less maintenance and significantly
longer engine life.
Superior shutdown protection prevents catastrophic engine damage due to low oil.
Prevents damage due to overheating.
Allows for smaller, light weight unit that operates 25% more efficiently than a revolving armature generator.
Produces a smooth output waveform for compatibility with electronic equipment.
Maximizes motor starting capability. Provides more surge capability than brushless generator designs.
Regulates the output voltage to ±2% prevents damaging voltage spikes.
For your safety
Transfers your vital electrical loads to the energized source of power.
Required (order separately)
Mounts near your existing distribution panel for simple, low cost installation.
For your safety
Selects the operating mode.
Constantly monitors utility voltage, setpoints 60% dropout, 80% pick-up, of standard voltage.
Prevents nuisance start-ups of the engine, set point approximately 10 seconds.
Ensures engine is ready to assume the load, setpoint approximately 10 seconds.
Allows engine to cool prior to shutdown, setpoint approximately 1 minute.
Operates engine to prevent oil seal drying and damage between power outages.
Maintains battery voltage to insure starting.
Protects generator from overload.
Ensures protection against mother nature. Hinged key locking roof panel for security.
Electrostatically applied powder paint for durability.
Quiet, critical grade muffler is mounted inside the unit to prevent injuries.
Makes for an easy, eye appealing installation.

Rating definitions - Standby: Applicable for supplying emergency power for the duration of the utility power outage. No overload capability is available for this rating. (All ratings in accordance with BS5514,
ISO3046 and DIN6271). Prime (Unlimited Running Time): Unit not recommended for prime power applications. Applicable for supplying electric power in lieu of commercially purchased power. Prime power is
the maximum power available at variable load. A 10% overload capacity is available for 1 hour in 12 hours. (All ratings in accordance with BS5514, ISO3046, ISO8528 and DIN6271).* Maximum wattage and
current are subject to and limited by such factors as fuel Btu content, ambient temperature, altitude, engine power and condition, etc. Maximum power decreases about 3.5 percent for each 1,000 feet above
sea level; and also will decrease about 1 percent for each 12° C (10° F) above 15.5° C (60°F).
