Description

Technical Field

[0002] For the installation of photovoltaic systems, photovoltaic modules are installed on photovoltaic brackets, and control boxes are installed on the bottom plates of photovoltaic modules. Positive and negative wiring are arranged on the control box. Due to the large number of photovoltaic modules, separate long line boxes are now arranged outside the rows of photovoltaic modules, and the wiring and bus heads of all photovoltaic modules are arranged in the line boxes.

[0003] During construction, since there are a large number of PV modules and some of them are far away from the junction box, it is not convenient for the workers to arrange the wiring of the PV modules, which affects the installation efficiency of the entire PV system.
