Protect Your Photovoltaic Systems Against Surge Damages

Weidmuller 3/27/2018

PV systems are installed in exposed locations and are directly imperilled by environmental influences. Therefore, the probability of a lightning impact that causes surge damage is high. Costly repairs, system downtimes and loss of revenues are the result.

A reliable overvoltage protection with future-proof performance ensures the profitability of PV systems in the long-term. PV inverters and the related infrastructure are well protected by VARITECTOR PU PV in accordance with the latest IEC and UL standards. VARITECTOR PU PV products are particularly powerful, compact and intended for use in PV systems with up 1,500 V.
