What do PV connector manufacturer think of lighting protection

 As the solar panels for outdoor surroundings, usually set up in open office or impose a guarantee of high sunshine. According to IEC61000-4-5 electrical environment classification, belong to four categories of power lines connecting the electrical environment, which interconnect the outdoor cables along the power cable by the laying of these cables and electronic and electrical circuit as the electrical environment.

Category 4 according to IEC electrical system of the lightning protection requirements, solar power generation system requires the input part of the lightning protection, which includes AC power input circuit, charge and discharge circuit and inverter circuit. Protection level line-line basis between the 2KV, 4KV line between the requirements to design. Forms of protection may need to press a different location for an up-level circuit protection. Since PV connector in the workplace environment harsh, long maintenance cycle, unattended, high service life requirements of special needs that require overvoltage protection solutions during the design, in addition to the surge capability of over-voltage protection devices to be considered , the entire program of work to protect life and anti-aging capabilities need to be assessed; 6KV shall be applied as protection.
