With the generator junction boxes of the GAK12 series, CITEL offers a solution to protect the DC side of any photovoltaic (PV) system with 12-MPPT and system voltages (Ucpv) up to 1200 Vdc against the effects of lightning and surge impulses. Depending on the configuration, the GAK12 are optimized for PV systems of lightning protection class III/IV with ≥ 4 down conductors according to Table 2, VDE 0185-305 Supplement 5, Fpr TS 50539-12 : 2013 and ground-mounted PV systems.
