Function
The surge protective device (SPD) protects photovoltaic systems and sensitive downstream equipment from transient overvoltages generated by lightning strikes or switching operations.
Using VG technology (varistor + gas tube), it safely diverts surge energy to ground while maintaining zero leakage current and ensuring long service life.
It limits the voltage reaching the PV array and inverter, providing both common-mode and differential-mode protection.
