Available in 100 parts. Since most of the energy storage components 100 are installed in the wild, the climate conditions are more severe, and the environment will generate a large amount of dust and be washed by rain. Therefore, the waterproof and dustproof capabilities of the energy storage cabinet are required to be very high.

This application provides an IP65 outdoor energy storage cabinet, as shown in Figure 1, including an energy storage component 100 and a shell 200. The housing 200 covers the outside of the energy storage component 100 to protect the energy storage component 100. The housing 200 is provided with an air inlet 210 and an air outlet 220.
