[0002] Energy storage photovoltaic technology is an important part of modern energy solutions. It combines the efficient energy conversion of solar power stations with the flexible scheduling capabilities of energy storage systems, providing an effective way to achieve stable output of renewable energy and optimize energy structure. In energy storage photovoltaic power stations, junction boxes, as key equipment for power management and distribution, are responsible for collecting, converting and transmitting the DC power generated by photovoltaic panels to energy storage equipment or power grids. The design of the junction box directly affects the operating efficiency and safety of the entire power station.

[0003] The junction boxes used in traditional energy storage photovoltaic power stations often have some design deficiencies, especially in terms of operation and maintenance.

Especially in emergency situations that require rapid processing, the small operating space greatly limits work efficiency. In addition, the design of traditional junction boxes in terms of heat dissipation, dust and water resistance, and ease of use often cannot fully meet the needs of efficient and stable operation of energy storage photovoltaic power stations.
