Description of the the DC Surge Protection
DC surge protection is designed to protect direct current (DC) electrical systems from sudden voltage spikes caused by lightning strikes, switching transients, or power fluctuations. These surges can damage sensitive components such as solar inverters, battery storage systems, and industrial DC equipment. Surge protection devices (SPDs) absorb and redirect excess voltage, ensuring system safety and longevity.
