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  NEMA MG1-22 EVALUATION

 SYSTEM TORSIONAL TESTED  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. Digital
voltage regulation at ±1%.

¡ SINGLE SOURCE SERVICE RESPONSE from Generac’s extensive dealer

network provides parts and service know-how for the entire unit, from the
engine to the smallest electronic component.

¡ 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.

Note: Fuel pipe must be sized for full load.

For Btu content, multiply ft3/hr x 2520 (LP) or ft3/hr x 1000 (NG).

For megajoule content, multiple m³/hr x 93.89 (LP) or m³/hr x 37.26 (NG).

Refer to "Emissions Data Sheets" for maximum fuel flow for EPA and SCAQMD permitting purposes.

STANDBY RATING: Standby ratings apply to installations served by a reliable utility source. The standby rating is applicable to varying loads for the duration of a power outage. There
is no overload capability for this rating. Ratings are in accordance with ISO-3046-1. Design and specifications are subject to change without notice.
