ABSTRACT:
A generator set for a transport refrigeration unit that is operable at a first frequency and a second frequency. The generator set includes a generator and a prime mover coupled to the generator. The prime mover selectively drives the generator in least at a first non-zero speed and a second non-zero speed. A sensor is in electrical communication with the generator to sense a load of the generator and to deliver a signal indicative of the generator load. A controller is in electrical communication with the generator, the prime mover, and the sensor, and receives the signal indicative of the generator load. The controller selectively operates the generator at one of the first speed and the second speed in response to the signal indicative of the generator load.
