Whether roof-mounted or ground-mounted, central or string inverter: photovoltaic systems are frequently equipped with lightning and surge protection. The new DEHN combo YPV SCI combined lightning current and surge arrester protects the d.c. side of PV systems from lightning and surge damage without additional backup fuses up to 1000 A. 

Arresters for system voltages of 600 V, 1000 V and 1500 V are available to achieve optimal coordination and efficient protection of terminal equipment. All versions have a width of only 4 modules.

 

The SCI technology also prevents switching arcs in case of an overload, thus ensuring fire protection. DEHN is the only company that offers surge arresters with innovative Short Circuit Interruption (SCI) technology thus providing maximum safety and fire protection for photovoltaic systems.

A fuse specifically dimensioned for PV systems in the bypass path ensures safe electrical isolation of the surge protective device. This fuse is also combined with a disconnection and short-circuiting device with Thermo Dynamic Control.
