The solar photovoltaic junction box has two main functions: the basic function is to connect the photovoltaic module and the load, solar junction box draw the current generated by the module and generate power. The additional function is to protect the lead wires of the components and prevent the hot spot effect.
Connection: As a connecting device, solar junction box the junction box serves as a bridge connecting solar modules and inverters and other control devices. Inside the junction box, solar junction box the current generated by the solar module is led out and introduced into the electrical equipment through the terminal and the connector. Protection: The protective function of the junction box includes three parts, solar junction box one is to prevent the hot spot effect through bypass diodes, solar junction box to protect the cells and components; the other is to seal and design waterproof and fireproof through special materials;solar junction box the third is to reduce the work of the junction box through special heat dissipation design Temperature, solar junction box reduce the temperature of the bypass diode, solar junction box and then reduce the leakage current of the component power loss.
The test standard of the junction box: The junction box should be tested before use, solar junction box mainly to check the appearance, tightness, fire rating, diode, solar junction box etc.
