Solar Junction Box, that is, solar cell module junction box. The solar cell module junction box is a connector between the solar cell array formed by the solar cell module and the solar charging control device, and its main function is to connect the power generated by the solar cell with the external circuit.
Types and characteristics of solar junction box
1. Traditional solar junction box
1) The shell has strong anti-aging and UV resistance.
2) Applicable to harsh outdoor environments.
3) The internal wiring seat is made of circuit board and plastic.
4) The cable is welded.
1. Glue sealing compact solar junction box
1) It has excellent high and low temperature resistance, fire resistance, aging resistance and ultraviolet resistance, and can meet the long-term use requirements in harsh outdoor environmental conditions.
2) Excellent waterproof and dustproof effect, sealed by glue filling.
3) Small appearance, ultra-thin design, simple and practical structure.
4) The bus bars and cables are connected by welding and crimping respectively, and the electrical performance is safe and reliable.
3. Special solar junction box for glass curtain wall
1) It has excellent high and low temperature resistance, fire resistance, aging resistance and ultraviolet resistance, and can meet the long-term use requirements in harsh outdoor environmental conditions.
2) Excellent waterproof and dustproof effect, sealed by glue filling.
3) Pocket-sized ultra-small appearance, simple and practical structure, suitable for thin-film photovoltaic modules.
4) The bus bars and cables are connected by welding and crimping respectively, and the electrical performance is safe and reliable.
Function of solar junction box
1. Connect
As a connector, the junction box acts as a bridge connecting solar modules and control devices such as inverters. Inside the junction box, the current generated by the solar module is drawn out and introduced into the electrical equipment through the terminal blocks and connectors.
2. Protection
The protection function of the junction box includes three parts. One is to prevent the hot spot effect through the bypass diode and protect the cells and components; the second is to use special materials to seal the design of waterproof and fireproof; Reduce the temperature of the bypass diode, thereby reducing the power loss of the component due to its leakage current.
