Lightning and surge protection for free field systems and solar parks

Protection against direct lightning strikes and transient overvoltage

A lightning protection system for free field systems and solar parks has two main goals:

  • Protection of the power plant area from lightning-related damage
  • Protection of the modules, inverters and monitoring systems from the effects of electromagnetic impulses

The investment volume is high and therefore system operators require permanent system availability – For this reason, the lightning-related risk should be calculated according to IEC 62305-2. The results of such a risk analysis form the basis for planning a lightning protection system.

Risk for existing systems

Existing systems are often insufficiently protected against direct lightning strikes and surges. We offer adequate products for retrofits and will be pleased to help you find a solution – just contact us:
