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.
