Lightning protection specification for inverter transformers of solar container communication stations

Before the inverter, a Type 1+2 protection device with VG technology, secondary current extinguishing capacity of 40 kA shall be used. The product must operate between -40°C and +85°C, have IP20 protection, alarm contact output, and comply with UTE C61-740-51, EN50539-11 . . Lightning protection projects for solar panels shall be designed in accordance with IEC 62305 national and international standards. The lightning protection project shall include an external lightning protection system, internal lightning protection system, grounding and equipotential bonding. . In summary, the components of the lightning protection measures required for grid-connected photovoltaic power stations are: ground light volt square array, DC transmission lines, metal pipelines, transmission lines, building machine rooms and equipment cabinets (including DC distribution cabinets. . Also, special features of combining overvoltage protection devices with SMA inverters are described. The document covers lightning protection in as far as it influences overvoltage protection. An EGC must run within the same circuit or raceway as the current-carrying conductors.
