Solar Power, another renewable clean energy out of Wind Power, is now widely used in various countries and territories. It is easy installation, flexible, stable and long lifetime. The solar power system is typically consisted by solar panel, junction box, invertor, PDU, battery and control system, etc. A lot of electrical/electronic devices are integrated in a small and limited space. It is no doubt that, lightning and harmful surge are the disasters. PTG provides comprehensive and effective solutions for Solar Power.

In accordance to IEC 62305 and the special requirement of solar system, below points should be considered when categorizing surge protection zones and selecting/ installing the SPD:

     1. Lightning protection zone (LPZ 0…3);

     2. Relative SPD test waveshapes (8/20 μs or 10/350 μs);

     3. Voltage protection level (especially the UP value of SPD AC side);

     4. Open circuit voltage at the DC side;

     5. Harmonic wave interference

In accordance to:

     1. IEC 61643-31: Low-voltage Surge Protective Device for Specific Application including d.c.  

     2. IEC 62305: Protection against Lightning

     3. IEC 61312: Protection against Lightning Electromagnetic Impulse

     4. IEC 61643-11: Low-voltage Surge Protective Devices
