The electricity generated by photovoltaic power generation can be directly connected to the grid or stored for emergency use. Photovoltaic power generation energy storage mechanism is a device or system used to convert and store the electricity generated by the photovoltaic power generation system so that it can be used for power supply when needed. It mainly consists of a photovoltaic power generation system, energy storage equipment and a power converter.

Most of the existing heat dissipation devices are air-cooled or water-cooled, and there is uneven heat dissipation during the heat dissipation process. In addition, air-cooled heat dissipation will cause the energy storage device to come into direct contact with the air. For energy storage devices installed at island airports, due to the high air humidity, it may affect the service life of the energy storage device.
