Description

technical field [0001] The invention relates to the technical field of solar photovoltaic power generation, in particular to an improved modularized photovoltaic module bypass element and a photovoltaic module junction box with the bypass element. Background technique [0002] Solar photovoltaic modules are devices that convert solar energy into electrical energy. In the production process of photovoltaic modules, the junction box plays an important role in the effective output of photovoltaic power. Its main function is to output the current generated by photovoltaic modules and protect solar photovoltaic modules. The current generated by each solar panel is relatively small, and it is necessary to use a photovoltaic junction box to electrically connect multiple solar panels to each other, so that the current generated by multiple solar panels can be aggregated and output to form a photovoltaic system with a certain power generation capacity. [0003] In actual use, the pho...

Problems solved by technology

Because of the different types and sizes of photovoltaic modules, the current junction boxes of photovoltaic modules also have many specifications, and it is necessary to produce shells and conductive terminals of different specifications, which leads to an increase in the production cost of the junction box and a decrease in production efficiency. Conducive to cost reduction and efficiency increase
