      FAQs<\/h2>\n

      Q1. What is the role of a 1500v dc spd t1+t2 in PV systems?<\/h3>\n

      It provides both lightning current (Type 1) and surge voltage (Type 2) protection, suitable for main DC entry points in 1500V PV plants.<\/p>\n

      Q2. Can the 1500v dc spd t1+t2 be installed in PV inverters?<\/h3>\n

      Yes, KY-15T\/G1500 is designed for inverter DC inputs up to 1500V, preventing overvoltage and ensuring inverter safety.<\/p>\n

      Q3. How does KY-15T\/G1500 compare to 1000V SPD models?<\/h3>\n

      It supports higher system voltage (1500V) and is ideal for large-scale PV plants where higher voltage strings are used.<\/p>\n

      Q4. Which standards cover KY-15T\/G1500?<\/h3>\n

      IEC 61643-31, GB\/T 18802.31, CE, UKCA, and RoHS certifications are covered.<\/p>\n<\/section>\n
