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.
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.

High energy MOVs equipped with specific thermal disconnectors and
related failure indicators.
The second level of power supply lightning protector using Class C protector for phase - in, phase - ground and in - ground full mode protection, the main technical parameters are: lightning through-current capacity greater than or equal to 40KA (8/20μs); residual voltage peak is not greater than 1000V; response time is not greater than 25ns.
