2. Inventory of photovoltaic high current junction box requirements From the electrical performance parameters of typical high-current modules of photovoltaic module factories and the selection of rated current of junction boxes, it can be seen that the M10 module with a current of 13.9A adopts the mature single-core solution in the industry and has sufficient safety margin, and uses diodes of higher specifications. The reliability of the high-current junction box is guaranteed. The 18.4A G12 ultra-high current module adopts a new dual-core solution (not verified by the industry), and the safety margin of the double-sided module is too small.

Under the background of realizing the "dual carbon goal", it is expected that in the next five years, my country's annual new installed capacity of photovoltaics will reach 62 to 68GW, and the cumulative installed capacity of China's photovoltaic power plants will reach 561GW in 2025. In the process

As a connecting device, the photovoltaic junction box serves as a bridge connecting solar modules and inverters and other control devices. Inside the photovoltaic junction box, the current generated by the solar module is led out and introduced into the electrical equipment through the terminal and

First of all, the function of the solar junction box panel is to convert the light energy of the sun into electrical energy, and then output the direct current and store it in the battery. The solar panel is one of the most important components in the solar power generation system, and its conversio
