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.
