The PV junction box mainly has two functions: the basic function is to connect the PV module and the load, lead the current generated by the module and generate power. The additional function is to protect the outgoing line of components and prevent hot spot effect.

As a connecting device, the photovoltaic junction box acts as a bridge to connect the solar modules, inverters and other control devices. The current generated by the solar module is led out and introduced into the electrical equipment through the terminal blocks and connectors inside the photovoltaic junction box. In order to minimize the power loss of the PV junction box on the module, the conductive materials used in the PV junction box shall have a small resistance, which is smaller than the contact resistance of the outgoing line of the bus strip.

The protection function of the photovoltaic junction box includes three parts: one is to prevent the hot spot effect through the bypass diode, and protect the cells and modules; The second is waterproof and fireproof design through sealing with special materials; The third is to reduce the operating temperature of the photovoltaic junction box and the temperature of the bypass diode through special heat dissipation design, thereby reducing the loss of the module power caused by its leakage current.

With excellent quality, the company's products have successfully passed the certification of TUV Rhineland, UL, CE&RoHS and other international authorities. The solar connector has obtained the national utility model patent ZL 2012 20008007.4. It is a domestic manufacturer of IP68 connectors. It has been successfully sold to Europe, America, Australia and other markets, and has assisted in the establishment of power stations in many countries. It is called European Solar Power Station. It is worth recommending. First of all, it has established a good strategic partnership with customers around the world to provide perfect sales services for customers around the world.

Relying on independent research and development capability, strict testing standards, perfect testing system, modern management mode and excellent elite team, adhering to the purpose of "survival by quality, development by innovation", the company takes the path of specialization, scale and internationalization, and is determined to build Sunyo into a world-class solar photovoltaic brand.
