Modern photovoltaic energy generation is streamlined to efficiency.
Reliable surge protection with future-proof performance is a must to
maximise system uptime and profitability. The VARITECTOR PU PV
series is designed for use in PV string combiner boxes for generator
voltages up to 1,500 V and complies with latest UL and EN standards for
PV-System with lightning rod system
In case the separation distance (typical >0,7m up to 1m) is
met a Type II SPD can be used. Does the separation distance
not meet the required value a Type I SPD should be in place
for the DC-wiring.
PV-System without lightning rod system
This is a common set up in which a Type II SPD has to be in
place for the DC-wiring.
