What do the PV connector Suppliers deal with its product

 Each PV connector, a solar panel cable access to the first solar system controller's convergence box. Therefore, convergence of the input box and the controller shown in Figure 2 should be used over-voltage protection design. Where A, B and C for the overvoltage protection device. For high voltage, high-reliability requirements of systems and equipment, you should use the gas discharge tube (GDT) and varistor (MOV) as series A, B and C to protect the location of the device to complete the outdoor cable lightning protection.

For voltages below 48VDC, low-power system that can directly use the GDT for overvoltage protection. Taking into account the failure mode overvoltage protection devices, require overcurrent protection devices with protection. Unattended or in places difficult to repair, should be used to recover from over-current protection devices. Tyco Electronics Circuit Protection Department for this type of lightning protection for different application requirements with a variety of environmental protection and protection program.
