A transportation refrigeration unit TRU and power system. The TRU and power system including a compressor, an evaporator heat exchanger operatively coupled to the compressor, and an evaporator fan configured to provide return airflow over the evaporator heat exchanger. The system also includes a return air temperature RAT sensor disposed in the return airflow and configured measure the temperature of the return airflow, a TRU controller operably connected to the RAT sensor and configured to execute a process to determine an AC power requirement for the TRU based on at least the RAT; a generator power converter, configured to receive a first DC power from a generator and transmit a second three phase AC power to a power management system, the power management system configured to direct AC power to the TRU based on the AC power requirement.
