Lightning protection products for solar power generation systems, PV SPD, ADN series.

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

The lightning protection product for solar power generation, the PV SPD "ADN Series," is an SPD that protects the PCS (Power Conditioner), solar panels, junction boxes, and collection boxes from induced lightning and direct strikes that invade the DC system of the PV system. According to a survey by NEDO (New Energy and Industrial Technology Development Organization), the number of PV damages caused by lightning is on the rise. The latest data (from 2008) indicates that about 28% of all damages are attributed to lightning, posing risks not only to expensive equipment like PCS but also to power generation stoppages. The PV SPD "ADN Series" features a separation mechanism that safely disconnects the SPD elements 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.

basic information

【Main Features】 ○ Compatible with Japan's PV specifications of DC600V and DC1000V systems, featuring a nominal discharge current of In20kA (maximum discharge current Imax40kA) and a high impulse withstand capability for long lifespan. ○ Separation function that safely disconnects high DC voltage and short-circuit current → Built-in short-circuit interruption mechanism (separation mechanism) allows for the safe disconnection of faulty SPD elements from the DC power system. ○ Plugin type with a plug retention mechanism. ○ High-reliability SPD with deterioration indication and alarm output → Equipped with a failure indication function and alarm output function that notifies when the internal elements of the SPD deteriorate due to multiple lightning surge intrusions, indicating the replacement lifespan of the SPD. 【Protected Targets】 Protection of components installed in the DC circuit of the solar power generation system from induced lightning and direct lightning strikes, including the PCS (Power Conditioner), solar panels, junction boxes, and collection boxes.
