DEHNcombo schützt PV-Anlagen
DEHN protects photovoltaic systems


Protect your PV system from lightning and surge damage

DEHNcombo YPV – a varistor-based type 1 + type 2 combined arrester – protects the DC side of the inverter, combiner box or PV modules.

Particularly interesting: This arrester is universally applicable, meaning that it can be used for applications ranging from small rooftop to multi-megawatt systems.


Protection concept for rooftop and free field systems

Rooftop and free field systems should be protected from direct lightning strikes and transient overvoltages with the help of a comprehensive protection concept consisting of external and internal lightning protection.

DEHNcombo YPV is suitable for earthed (earthing of DC+ or DC-) and floating systems and can be used up to 10 kA without additional backup fuse. The arrester is available for system voltages UCPV ≤ 1200 V and ≤ 1500 V, thus ensuring effective protection of terminal devices.
