1. A system for powering a transport refrigeration unit (TRU), the system comprising:
one or more batteries configured to supply a DC battery voltage;
an inverter/charger coupled to the one or more batteries and configured to convert the DC battery voltage to an AC output voltage for powering an electric motor, the electric motor coupled to a compressor of the TRU;
an automatic transfer switch (ATS) connected to the inverter/charger, the electric motor, and a shore power connector, the ATS configured to automatically switch power delivery to the electric motor between the AC output voltage and an AC shore power supply voltage; and
an electrical vehicle (EV) charging port coupled to one or more of the one or more batteries and the inverter/charger, the EV charging port configured to receive a charging voltage from an EV charger.
