Since solar combiner boxes are installed outdoors, lightning and transient overvoltage protection is essential. A PV-specific DC surge protector, or SPD (Surge Protection Device), is installed in parallel with the main conductors at the DC output of the solar combiner box. At the same time, you also keep the amortization time of the system as short as possible. Use our lightning and surge protection for photovoltaic systems to. . It acts as a safeguard against lightning strikes and electrical surges, protecting sensitive equipment and maintaining system integrity.
