T1+T2 PV Surge Protection Device FLP-PV1000G-S

T1+T2 PV Surge Protection Device FLP-PV1500G-S

FLP-PVxxxG series is the range of combined devices for discharging lightning currents (Type 1 / Class I), and protecting against induced transient over-voltages (Type 2 / Class II), for Photovoltaic installations, in accordance with EN 50539-11, EN 61643-31, IEC 61643-31.

This DC surge protective devices offer unique hybrid technology and multiple benefits not found in traditional surge protection solutions. The design incorporates a combination of MOV and GDT technology to maximize the SPD’s performance level and reliability. This technology is optimized for robustness and network stability, providing the highest level of protection available.

This combined arrester was specially developed for use in PV installations and protects the DC side of the inverter against partial lightning currents and surges.

Install LSP's surge protection device (SPD) for the inverter, junction boxes, combiner box and panels to protect both the AC and DC sides of the solar power plant.
