PV surge arrestors, also known as surge protective devices (SPDs), are critical for safeguarding photovoltaic (PV) systems from overvoltage events caused by lightning strikes or other electrical disturbances. These devices are designed to limit the voltage and divert the surge current away from sensitive PV equipment, such as solar panels and inverters, thus preventing damage and ensuring the long-term reliability of the system.
