Surge protection for photovoltaic systems helps to reduce the amortization time while increasing the availability of your photovoltaic system. Protective devices for photovoltaic systems differ from surge protection for linear direct currents. Our application-specific portfolio of surge protective devices for photovoltaic systems offers the right components from power supply to the protection of signal and data lines.

Pluggable VAL-SPP-T1-1000DC-PV-UT-R lightning arresters
The plug-in type 1 lightning current arresters VAL-SPP-T1-1500DC-PV... and VAL-SPP-T1-1000DC-PV... reliably protect two-position, insulated DC systems in photovoltaic systems against direct lightning strikes and surges. They are suitable for ground-mounted PV systems and roof systems as well as for string combiner boxes. Users benefit from high system availability, increased operational safety, and simple, safe installation. The devices are designed for system voltages of 1,000 V DC or 1,500 V DC and are optionally available with remote indication contact.
Pluggable type 2 surge protective device – VAL-SPP-T2-1000DC-PV-UT-R
With the 2+V circuit for two-position, isolated DC voltage systems, the pluggable type 2 surge protective device from the VAL-SPP product family provides reliable system protection for applications with 600 V DC, 1,000 V DC and 1,500 V DC no-load voltage Uocstc. With these new protective devices you will benefit from the optimized disconnect device and advantages during installation and maintenance. The type 2 VAL-SPP-T2-...-PV... surge protective devices are available with and without remote signaling.
Safe Protection Plus is the new product family for surge protection. With the new varistor-based VALVETRAB SPP surge protective devices, we offer robust surge protection with future-oriented installation and safety features.

One-piece T1/T2 lightning current arrester for photovoltaic systems
The one-piece T1/T2 lightning current arresters for two-position, isolated DC voltage systems with 600/1,000/1,500 V DC have a short-circuit current rating of up to 2,000 A. The products have KEMA approval and are available with or without floating remote indication contact. The extended insertion funnels on the main connections and the raised screw shafts result in increased resistance to creepage and safer installation. The visual status indicator on the device provides information about the status of the protective device.
One-piece type 2 surge protection for photovoltaic systems
The type 2 surge protection for two-position, isolated DC voltage systems with 1,500 V DC is short-circuit-proof up to 2,000 A. The extended insertion funnels and the raised screw shafts provide better resistance to creepage, thus making installation safer. Optional remote signaling allows the protective devices to be integrated into monitoring systems. When performing visual inspections on site, the visual status indicator on the device provides information about the status of the surge protection.
Photovoltaic systems require special protective circuits. Depending on the system configuration and grounding conditions, we provide suitable protective devices that can safely handle these high DC voltages.
Preassembled set solutions simplify the installation of surge protection in your photovoltaic system.
Tracking and monitoring systems must also be protected against interference and data loss. Use appropriate protective devices to protect the data and control cables.
