As a trusted surge protection devices manufacturer with decades of expertise, LSP delivers proven reliability for customers worldwide. Our 1500V DC Surge Protective Devices are engineered with advanced MOV + GDT technology and superior performance, earning the trust of over 1,200 companies, including solar PV manufacturers and industrial facilities.
Our 1500V DC SPD series is designed with the features you need for fast, reliable installation and maintenance.
Unprotected PV systems are highly vulnerable to lightning strikes and overvoltage events, which can lead to costly damage and downtime. With compliance to IEC 61643-31 standards, our 1500V DC SPDs effectively mitigate these risks. We manufacture millions of DC SPDs every year, helping businesses protect their critical equipment and ensure long-term system reliability.
Our 1500V DC Surge Protection Devices (SPDs) provide up to 99.99% protection against transient overvoltages, ensuring the highest level of safety for your DC infrastructure.
Engineered for utility-scale solar energy systems and commercial PV plants, these SPDs combine advanced MOV technology with robust metal and plastic housings to deliver comprehensive protection for sensitive equipment.
1500V DC Surge Protective Devices are crucial for large-scale solar farms because they safeguard long strings of PV panels and central inverters from high-voltage surges. Without proper protection, lightning events and switching transients can cause irreversible damage, leading to significant financial losses and system downtime.
Yes, 1500V DC SPDs are installed in parallel with the DC system, while a 1500V DC fuse or DCB is connected in series upstream. This ensures that if the SPD fails, the circuit is safely disconnected, protecting the PV system and sensitive equipment.
