La description
DC surge protective device, protect against lightning surge voltages in solar system (PV 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), ely if the line routing is external and long High energy Movs equpped with specific thermal disconnectors and related failure indicators .

FAQ :
Surge protector, also name lightning arrestor protector, it’s provides safety protection for various electronic equipment, instruments, and communication lines. When an electrical circuit or communication line suddenly generates a peak current or voltage due to external interference, the surge protector can conduct the shunt in a very short time, thereby avoiding the damage of the surge to other equipment in the circuit.
