Transport refrigeration unit, and system and method forautomatically switching from first power mode to secondpower mode of transport refrigeration unit

A method for automatically switching from a first power mode to a second power mode of a transport refrigeration unit (TRU), the method comprising:

• activating, by a geo-fencing activation engine, a geo-fencing mode of the TRU operating in the first power mode, wherein the activation of geo-fencing mode triggers a continuous and automatic determination of geo-location coordinates of the TRU;
• determining, by a location determination engine, if the TRU is on board a marine vessel in a first geographical region responsive to the activation of the geo-fencing mode;
• and
• automatically switching, by a power mode switching engine, from the first power mode to the second power mode for the TRU based on a positive determination, wherein the first power mode corresponds to a combustion-driven power source and the second power mode corresponds to a stand-by power source.

A transport refrigeration unit (TRU) comprising:

• a processor communicably coupled to a memory storing instructions executable by the processor and configured to:
• activate a geo-fencing mode of the TRU operating in the first power mode, wherein the activation of geo-fencing mode triggers a continuous and automatic determination of geo-location coordinates of the TRU;
• determine if the TRU is on board a marine vessel in a first geographical region responsive to the activation of the geo-fencing mode;
• and
• automatically switch from the first power mode to the second power mode for the TRU based on a positive determination, wherein the first power mode corresponds to a combustion-driven power source and the second power mode corresponds to a stand-by power source.
