What is the function of the photovoltaic junction box

As a connecting device, the photovoltaic junction box serves as a bridge connecting solar modules and inverters and other control devices. Inside the photovoltaic junction box, the current generated by the solar module is led out and introduced into the electrical equipment through the terminal and the connector. In order to minimize the power loss of the photovoltaic junction box to the components, the conductive material used in the photovoltaic junction box requires a small resistance, which is smaller than the contact resistance of the lead wire of the busbar.

To 1) The traditional photovoltaic junction box shell has strong anti-aging and ultraviolet resistance;

To 2) The traditional photovoltaic junction box is suitable for outdoor harsh environment;

To 3) The internal wiring seat is made of two materials: circuit board and plastic;

To 4) The power of the photovoltaic junction box can be changed by the welding type of the cable and the assembly of different diodes.
