[0022] The current photovoltaic power generation and energy storage equipment does not have an efficient heat dissipation structure when in use, and only relies on natural ventilation for heat dissipation. Due to the particularity of the working position of the photovoltaic panel, the photovoltaic power generation and energy storage equipment will be exposed to sunlight for a long time, which makes the natural ventilation heat dissipation method unable to quickly dissipate heat.

It can be understood that the inverter, transformer and other related electronic accessories required in this embodiment should be reasonably selected, configured and installed.

[0026] Specifically, when using the photovoltaic power generation and energy storage equipment, the staff will be able to set up the photovoltaic power generation and energy storage equipment at a suitable location and then put it into use.
