Have you installed a photovoltaic system on your building? Perhaps you also operate a wind farm or solar power plant? – Then take steps to protect your investments and yield against damage caused by lightning and surge voltages.

Your advantages

  • Complete protection from generation, through feed-in, to communication, thanks to a comprehensive product range
  • Optimally tailored protection, thanks to sector-specific products
  • System availability is ensured around the clock, thanks to surge protection
  • Optimized maintenance planning, thanks to remote signaling

Protect your investment

Renewable energy sources are becoming increasingly important. Wind power and photovoltaics have seen a significant increase in installations.

However, the systems are at particularly high risk from lightning currents and surge voltages. This is because most are situated in exposed locations or they are at particular risk of lightning strike due to their surface area.

Take preventive action: surge protection significantly increases the availability of your systems.

Protection for photovoltaic systems

Surge protection for photovoltaics from Phoenix Contact

Surge protection for photovoltaics

PV systems require special protective circuits. Depending on the system configuration and grounding conditions, we provide suitable arresters that can safely handle these high DC voltages.

Pre-assembled set solutions simplify the installation of surge protection in your PV system.

Tracking and monitoring systems must also be protected against interference and data loss. Use appropriate arresters to protect the data and control cables.

String combiner boxes with external string fuse

SCB with string fuse outside the control box

SCB with external string fuse

The string combiner boxes (SCBs) with string fuse outside the control box are a convincing option, thanks to their compact design and flexible field of application. Placing the fuse on the outside significantly reduces the thermal load of the internal components, as the fuses can optimally discharge their waste heat into the environment.

String combiner boxes with standard string fuse
