Maximum safety for your PV system – support structures tested for lightning protection from OBO

Yes. To prevent injury and property damage, E DIN VDE 0100-712 requires protective equipotential bonding. This must be realised with at least 6 mm² of copper. We recommend planning with 10 mm² of copper to be prepared for the future.”

Important in case of an existing lightning protection system: If the required separation distance between the PV support structure and lightning protection system cannot be maintained, the equipotential bonding must be realised as lightning protection equipotential bonding in accordance with DIN IEC EN VDE 0185-305-3. This means at least 16 mm² of copper.

In all cases, an 8 mm aluminium conductor can be used as an alternative (typical lightning arrester wire).

Yes, they have to be marked as PE. Note: A green-yellow conductor must not be laid without protection outdoors.

The PV support structures do not replace a lightning protection system. If necessary, however, defined air-termination rods can optionally be fastened to the support structures. These are designed for use with the system for lightning protection class 3. All corresponding OBO connection components of the support structure are tested in accordance with the respective component lightning protection standard.

Please note: In this case, the further path of the lightning currents must be observed and, if necessary, ensured by suitable type 1+2 surge protective devices. OBO offers a complete product range. Inquire about our selection aid for PV surge protection.
