Because of their often exposed installation sites and large collection areas, photovoltaic (PV) installations are at risk from both direct and indirect lightning strikes.
Whilst only an external lightning protection system can protect PV installations from a direct strike, Type 2 surge protection devices (SPDs) protect the inverters and AC electrical system from surges induced by nearby indirect lightning strikes and also surges transmitted by the AC electrical grid.
With this in mind, surge protection on DC and AC electrical supplies is covered with the DEHNguard RED/Line range of SPDs. Meeting the requirements of IEC 61643-1/EN 61643-11 and the new BS 7671 Amendment 1 section 534, the modular Red/Line range offers the advantage of being DIN-rail mounted with pluggable protection modules and fully energy coordinated to offer optimum protection.
