15 Jan Protection of photovoltaic installations
SPF series devices are especially designed to protect photovoltaic installations. A set of photovoltaic pannels of a photovoltaic installation- also known as a string, are exposed to lightning strikes. As a result of this kind of phenomenon, overvoltages and overcurrents that affect the photovoltaic installation are induced. Therefore, the protection of photovoltaic installations is important.
On the other hand, solar panels of a self-consumption photovoltaic installation are connected both to the interior of a consumption network and the transmission or distribution network through a physical electrical connection. The purpose of modular switchboards of SPF series devices is to protect photovoltaic generating installations up to 1,000Vdc. Therefore, the SPF series includes Type 2 transient overvoltage protection devices, in accordance with the IEC 61643-1 and EN 61643-11 standards.
