SPD 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.

Key Features
Why they are needed
Protect sensitive equipment: Solar systems have sensitive electronics, like inverters, that are vulnerable to damage from voltage spikes.
Prevent downtime and revenue loss: Damage from surges can cause a system to stop working, leading to lost revenue, especially for larger commercial or utility-scale systems.
Safeguard against various surges: SPDs protect against both direct and indirect lightning strikes, as well as surges from grid switching or other electrical issues
