AC Surge Protective Device

JCSPV Photovoltaic surge protection Device 1000Vdc Solar surge

JCSPV photovoltaic surge protection devices are specially designed to protect photovoltaic power supply networks from the damaging effects of lightning surge voltages. By utilizing specialized varistors, these devices provide common-mode as well as common-differential mode protection, ensuring complete protection against potential electrical interference. This advanced technology enables photovoltaic systems to operate with greater reliability and resiliency even in the face of unpredictable environmental conditions.


    Indirect lightning strikes pose a significant threat to the integrity of photovoltaic (PV) systems. While anecdotal observations of lightning activity may not accurately reflect the potential for lightning-induced overvoltages in PV arrays, the damaging effects of indirect lightning strikes on sensitive PV equipment cannot be underestimated. The high cost of repairing or replacing damaged components, coupled with the negative impact on overall PV system reliability, highlights the urgent need for effective protective measures.
    When lightning strikes a solar photovoltaic system, transient currents and voltages are generated within the system's electrical wiring loops, causing potential damage to various electrical and electronic components such as photovoltaic panels, inverters, control and communication equipment, and building installation equipment. of insulation and dielectric faults. It is worth noting that combiner boxes, inverters and MPPT (maximum power point tracker) equipment are particularly susceptible to failure in this situation.
    Our JCSPV surge protection devices play a vital role in preventing high-energy surges from causing voltage damage to photovoltaic system electronics. Specifically, the JCSPV DC surge protector SPD Type 2 is designed for isolated DC voltage systems with ratings ranging from 600V to 1500V DC, with short circuit current ratings up to 1000 A. The unit is designed for installation on the DC side. Photovoltaic systems use advanced technology to protect terminal equipment such as solar panels and inverters from lightning surge currents. By implementing these protective measures, PV system operators can significantly increase the resiliency and longevity of their installations in the face of unpredictable lightning events.
     Our JCSPV surge protection devices are carefully designed to protect the photovoltaic supply network from the harmful effects of lightning surge voltages, providing unparalleled protection for your photovoltaic system, especially during thunderstorms and severe weather conditions. This proactive approach not only safeguards the longevity and performance of your PV system, it also significantly reduces the risk of damage, ensuring uninterrupted operation and giving you peace of mind.
    An outstanding feature of our photovoltaic surge protection devices is their ability to handle photovoltaic voltages up to 1500 V DC, setting new standards for robust protection. With a nominal discharge current In of 20kA (8/20 µs) and a maximum discharge current Imax of 40kA (8/20 µs) per path, the device provides excellent protection against lightning surges, thereby enhancing the resilience of the photovoltaic system. .
    Additionally, our plug-in module design makes it easy to install and maintain equipment, streamlining the process and minimizing downtime. The device's usability is further enhanced by the inclusion of a user-friendly status indication system with visual cues, with a green light indicating normal function and a red light indicating the need for replacement. This intuitive feature simplifies monitoring and maintenance of PV systems, ensuring optimal performance at all times.
    It is worth noting that our photovoltaic surge protectors have a high protection level of ≤3.5KV and meet the strict requirements of IEC61643-31 and EN 50539-11 standards. This compliance highlights the device’s reliability and effectiveness in protecting your PV system from overvoltage caused by lightning strikes, providing a comprehensive safety net for your valuable investment.
    With their advanced features and unparalleled protection, our JCSPV surge protection devices become the ultimate solution for all your PV system protection needs, providing peace of mind and uninterrupted performance in the face of unpredictable environmental challenges.
