O 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 %
O 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.
O GENERAC TRANSFER SWITCHES. Long life and reliability are
synonymous with GENERAC POWER SYSTEMS. One reason for this
confidence is the GENERAC product line is offered with its own transfer
systems and controls for total system compatibility.
