Claim 13:
14. A method of generating and directing power to a transportation refrigeration unit (TRU) system having a compressor configured to compress a refrigerant, an evaporator heat exchanger operatively coupled to the compressor; an evaporator fan configured to provide return airflow from a return air intake and flow the return airflow over the evaporator heat exchanger; a return air temperature (RAT) sensor disposed in the return airflow and configured measure the temperature of the return airflow; and a TRU controller, the method comprising:
determining an AC power requirement for the TRU based on at least the RAT;
a operably connecting a generator power converter to a DC generator, the generator power converter configured to receive a first DC power provided by the DC generator and transmit a second DC power;
operably connecting an energy storage system, the energy storage system operable to at least one of receive the second DC power, provide first three phase AC power, and receive a second three phase AC power; and
operably connecting a power management system to the energy storage system and the TRU, the power management system configured receive the second three phase AC power to direct power the TRU based at least in part on the AC power requirement.
