DEHN + SOHNE surge protection for PV systems

DEHN + SOHNE offers lightning protection components and surge protection devices for photovoltaic systems.

Starting with support in the planning phase, followed by consultation with regard to the selection of devices, components and systems, up to the final inspection and documentation, the company is a reliable partner. The Lightning Protection Guide provides information on the installation of lightning protection systems in accordance with standards, while the company’s technical support offers expert advice.

Systems are offered for one-family houses up to PV power plants. The modular systems allow for lightning and surge protection measures for all kinds of PV systems - starting with external lightning protection with an air-termination system, down-conductor system and earth-termination system, along with equipotential bonding and up to lightning and surge protection.

Even when devices overload, the arrester control of the DEHNguard PV SCP ensures a safe state of operation without a risk of fire in the system. The combined disconnection and short-circuiting device is able to carry the short-circuit current until corrective maintenance of the PV system.

The Type 1 combined lightning current and surge arrester DEHNlimit PV 1000 protects the generator and inverter against surges in case of direct lightning strikes. Potential short-circuit currents up to 100 A at a photovoltaic voltage up to 1000 VDC will be interrupted within a few split seconds.

The DEHNcon-Ha module, in the field of an isolated air-termination system, is usable wherever proximities have to be avoided. The HVI conductor light is used not only controls proximities, but it is also individually adjustable to the architectural design by selecting the corresponding colour of the paint coating.
