A power system of a vessel includes a first AC bus; a second AC bus; a bus tie that electrically disconnects the first AC bus and the second AC bus when in an open position; a first power source and a first set of one or more non-propulsion components of the vessel that are electrically connected to the first AC bus; a second power source and a second set of one or more non-propulsion components of the vessel that are electrically connected to the second AC bus; a DC bus; a first transformer that galvanically isolates the DC bus from the first AC bus; a second transformer that galvanically isolates the DC bus from the second AC bus; a first AC/DC inverter coupled between the first AC bus and the DC bus; and a second AC/DC inverter coupled between the second AC bus and the DC bus.

A thermal management system for an energy storage container includes an enclosed compartment containing an energy storage unit, an air temperature control unit configured to cool an interior of the enclosed compartment, and at least one inverter connected to a coolant circuit, which is separate from the air temperature control unit, and configured to be cooled by a coolant in the coolant circuit. The thermal management system also includes a radiator located outside of the enclosed compartment, the radiator being connected to the coolant circuit, wherein the coolant in the coolant circuit flows through the radiator, and at least one fan located alongside the radiator, outside of the enclosed compartment, the at least one fan being configured to blow air across the radiator to cool the coolant flowing through the radiator.

A cooling system may include a housing including an inlet; an outlet; a duct assembly between the inlet and the outlet; and at least one fan located to direct airflow from the inlet, through the duct assembly, and out the outlet; the duct assembly including: a first duct having an entrance facing the at least one fan and an exit normal to the entrance; a second duct having an entrance facing the at least one fan and an exit normal to the entrance; a central passage for receiving airflow from the first duct exit and the second duct exit; a third duct having an entrance fluidly coupled to the central passage; a fourth duct having an entrance fluidly coupled to the central passage; and a plurality of heat sinks located in the third and fourth ducts.
