Generally, the junction box is composed of a box cover, a box body, a terminal block, a diode, a connecting wire, and a connector.
The requirements for use are as follows:
1) The shell should have strong anti-aging and ultraviolet resistance;
2) Meet the requirements of outdoor harsh environmental conditions;
3) The self-locking function makes the connection more convenient and firm;
4) There must be waterproof sealing design, scientific anti-electric shock insulation protection, and better safety performance;
5) The terminal should be installed firmly, and the busbar should have good weldability;
6) The main function of the diode is the unidirectional conduction function;
7) Connector, connecting wire: with good insulation performance, male and female plugs with self-locking function is more convenient and reliable for solar panels and electrical connection.
