The key international reference for DC SPDs in solar systems is IEC 61643-31, which defines performance and testing requirements for photovoltaic surge protection devices. Typical DC voltage ratings include 600 V, 1000 V, 1100 V, and 1500 V DC, depending on system design. 35 and essential for protecting expensive inverters, charge controllers, and monitoring equipment from voltage transients that occur daily in photovoltaic installations. Additionally, it restricts the overvoltage's amplitude to a value that is safe for the electrical infrastructure and switchgear. Although it lasts only microseconds, it can carry significant energy and stress connected equipment. In solar power plants, surges commonly result from. . Use Type 2 SPDs for standard protection against indirect lightning strikes, or implement a three-level approach with Types 1, 2, and 3 SPDs in high-risk areas for comprehensive coverage.
