FEATURES

 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.

 TEST CRITERIA:

 PROTOTYPE TESTED

 SYSTEM TORSIONAL TESTED

 NEMA 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.

 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.

HOME STANDBY SPECIFICATIONS Home Standby – 18kW

• Generac (OHVI) Design

• ”Spiny-lok” cast iron cylinder walls

• Electronic ignition, spark advance
and compression release

ENGINE

• Full pressure lubrication system

• Low oil pressure shutdown system

• High temperature shutdown

• Revolving field

• Displaced phase excitation

• Automatic voltage regulation

GENERATOR

• UL 2200 Listed

• Fully Automatic

• 100, 200 or 400 Amp (options)

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.

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.
