INNOVATIVE DESIGN & PROTOTYPE TESTING are key components of
GENERAC’S success in “IMPROVING POWER BY DESIGN.” But it
doesn’t stop there. Total commitment to component testing, reliability
testing, environmental testing, destruction and life testing, plus testing
to applicable CSA, NEMA, EGSA, and other standards, allows you to
choose GENERAC POWER SYSTEMS with the confidence that these
systems will provide superior performance.

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.



SINGLE SOURCE SERVICE RESPONSE from Generac’s 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. 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.

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.

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 amperage to insure starting.

Protects generator from overload.

Ensures protection against mother nature. Hinged key locking roof panel for security.
Electrostatically applied epoxy paint for durability.

Quiet, critical grade muffler is mounted inside the unit to prevent injuries.

Makes for an easy, eye appealing installation.
