Due to their exposed installation sites and large collection areas, photovoltaic (PV) installations are at a high risk of damage due to both direct and indirect lightning strikes. The subsequent damage from these surges can cause serious damage to PV installations, expensive inverters and the building electrical system.
Whilst only an external lightning protection system can protect PV installations from a direct strike, Type 2 surge protection devices (SPD’s) protect the inverters and AC electrical system from surges induced by nearby indirect lightning strikes and also surges transmitted by the AC electrical grid.
Surge protection on DC and AC electrical supplies are covered with the DEHNguard RED/Line range of SPD‘s.
Meeting the requirements of IEC61643-1/EN61643-11and the new BS7671 amendment 1 section 534, the modular Red/Line range offers the advantage of being DIN rail mounted with pluggable protection modules and fully energy co-ordinated to offer optimum protection.
