Protection Of Photovoltaic Systems
Whether it is a residential photovoltaic system on the roof of the family house, industrial photovoltaic powerplant or photovoltaics on the roof of an office building, you need to protect this installation against overvoltage by surge protection system. Hakel company spol. s r.o. has a big experience in this area and offers solutions for all types and sizes of solar power systems.

SPC PV is a lightning and surge arrester type 1+2 according to EN 61643-11 and EN 50539. It is designed for protection of positive and negative busbars of photovoltaic systems against the surge effects. These arresters are recommended for use in the Lightning Protection Zones Concept at the boundaries of LPZ 0-2 (according to IEC 1312-1and EN 62305). Particular varistor sectors are equipped with internal disconnectors, which are activated when the varistors fail (overheat). Operational status indication of these disconnectors is partly mechanical (by exserted red signaling target in case of failure) and partly remote monitoring (by potential free change over contacts – only DS types).
