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

Protect expensive PCS (Power Conditioners) and various measuring devices from lightning damage! Launching lightning protection products, PV use SPD 'ADN Series'!
Showden Co., Ltd. (4-3-8 Taihei, Sumida-ku, Tokyo, President Mitsuaki Ota) will launch the lightning protection product for photovoltaic (PV) systems, the PV SPD "ADN Series," starting in April 2013. The ADN Series is an SPD that protects the power conditioning system (PCS), solar panels, junction boxes, and combiner boxes from induced lightning and direct strikes that enter the DC system of PV systems. The PV market has rapidly expanded since the introduction of the "Feed-in Tariff System for Solar Power Generation" in July 2012. Additionally, a survey by NEDO (New Energy and Industrial Technology Development Organization) indicates a rising trend in the number of PV damages caused by lightning. According to the latest data from 2008, approximately 28% of all damages are attributed to lightning, which poses risks not only for expensive equipment like PCS but also for power generation interruptions. Showden has developed lightning protection products to safeguard PV systems from lightning damage and enable safer system operation. 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.
