Supports high voltage systems of DC600V and DC1000V! PV SPD that protects expensive power conditioners and various measuring instruments from lightning damage.

The lightning protection product for solar power generation, the PV SPD "ADN Series," is designed to protect components such as the PCS (Power Conditioner), solar panels, junction boxes, and collection boxes from induced lightning and direct strikes that invade the DC system of PV systems. According to a survey by NEDO (New Energy and Industrial Technology Development Organization), the number of PV damage incidents due to lightning is on the rise. The latest data from 2008 indicates that approximately 28% of all damages are attributed to lightning, posing risks not only to expensive equipment like PCS but also to power generation interruptions. The PV SPD "ADN Series" features an internal separation mechanism that allows for the safe disconnection of the SPD element from the DC system in the event of degradation or failure due to lightning. It is a high-end model equipped with plug-in capabilities, SPD degradation indicators, and alarm outputs. For more details, please contact us or download the catalog.
