Power lightning protection includes power lightning protection module, power lightning protection box, power lightning protection socket, etc.
The difference between power lightning protection module and power lightning protection box is the difference in size, the latter is more powerful and has a lightning counter, etc., but the module is easier and cheaper to install than the lightning protection box. [1]

Lightning protector is used to protect various electrical equipment in the power system from lightning overvoltage, operating overvoltage, frequency transient overvoltage impact and damage to an electrical appliance. The main types of lightning arresters are protection gaps, valve-type lightning arresters and zinc oxide lightning arresters. Protection gaps are mainly used to limit atmospheric overvoltage and are generally used to protect incoming sections of distribution systems, lines and substations. Valve type lightning arresters and zinc oxide lightning arresters are used for substation and power plant protection, and are mainly used to limit atmospheric overvoltage in 500KV and below systems, and will also be used to limit internal overvoltage or as backup protection for internal overvoltage in ultra-high voltage systems.

This series of surge protector device(SPD)is suitable for new energy solar power generation system, and the maximum continuous working voltage is DC500V, 800V, 1000V, 1200V. The installation position is in the DC power supply system to protect indirect lightning current, direct lightning current or other transient overvoltage.
Surge protective device, protect against lightning surge voltages in solar system (photovoltaic power supply system).
These units must be installed in parallel on the DC networks to be protected and provide common and different modes protection. Its installed location are recommended at both ends of the DC power supply line (solar panel side and inverter/converter side), especially if the line routing is external and long.
High energy MOVs equipped with specific thermal disconnectors and related failure indicators.
