New energy lightning protection devices (spd) (also known as a surge protector, lightning protector, overvoltage protector, lightning surge arrester) are mainly divided into AC/DC lightning surge protectors for solar panels, wind power plants, and photovoltaic (PV) solar lightning protection. The DC voltage range is generally 300~1500VDC, and the AC is 385V, 480V, 690V, 1000VAC, etc. SPD surge protectors are widely used in combiner boxes, for solar inverters, wind box transformers, and other equipment. according to GB18802.1 and IEC61643-1 standards. Surge protectors have a strong lightning current discharge capability, suitable for surge protection of DC power equipment of solar power generation systems and wind power systems.
