Application Of Cable Terminals In Photovoltaic Combiner Boxes
Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (modules), controllers and inverters, and the main components are composed of electronic components. After the solar cells are connected in series and packaged for protection, they can form a large-area solar cell module, and then combined with power controllers and other components to form a photovoltaic power generation device.
The combiner box is a cable lugs device in the photovoltaic power generation system to ensure the orderly connection and convergence function of photovoltaic modules. This device can ensure that the photovoltaic system is easy to cut off the circuit during maintenance and inspection, and reduce the scope of power outage when the photovoltaic system fails. The combiner box means that users can connect a certain number of photovoltaic cells of the same specifications in series to form photovoltaic strings, and then connect several photovoltaic strings in parallel to the photovoltaic combiner box. After the convergence in the photovoltaic combiner box, it is used in conjunction with the controller, DC distribution cabinet, photovoltaic inverter, and AC distribution cabinet to form a complete photovoltaic power generation system and achieve grid connection with the city power.
Recently, a highly scalable new standardized combiner box can be used for civil and commercial photovoltaic applications. Its innovative concept can meet about 75% of the current standard requirements for combiner boxes, helping suppliers work more safely and conveniently while significantly reducing their costs.
The integrated wire lugs technology provided by Youle Electric can significantly reduce assembly time while minimizing the risk of errors and their consequences. For installers, the connection concept for wiring the system brings many advantages. The integrated terminal structure saves a lot of assembly time and greatly improves electrical lugs efficiency. In addition, terminal lugs also provides two copper lugs methods: panel type and track type, which can provide terminals for specific application types such as general purpose or grounding.
