DC Surge Protection Device SPD for Photovoltaic PV solar Applications


Photovoltaic applications are found within the Solar Industry. It is important to protect Photovoltaic (PV) Panels from surge to allow maximum ROI to the investors. By far, the biggest culprit of electrical surges rendering damage to solar panels is direct and indirect lightning strikes to the system.

SLP40-PV & FLP7-PV series for installation of DC side to protect the terminal device in a PV system, like solar panels and inverters against the effects of lightning surge current.
