The Y or X cable is used to connect three or four elements of a PV system, such as the connection between PV panels, inverters and surge protection boxes. The cables are available in different connection variants.
The wide range of PV application specific labels and cable markers make the installation complete and make it easy to keep an overview during maintenance.
PV systems are directly exposed to environmental influences because they are always installed in exposed locations. Therefore the probability of lightning strikes and resulting overvoltage is high. The components of unprotected PV systems are again and again considerably damaged.
Type I devices are available in 1,000 and 1,500 V DC versions
Type II devices are available in 600, 1,000, 1,200 or 1,500 V DC versions
Optionally with or without a remote signalling contact
The entire product portfolio for photovoltaic systems complies with the current photovoltaic standard EN 50539-11
PV Protect is the compact solution for optimum protection of the inverter against overvoltages The ready-to-connect boxes are available for different system voltages and can be supplied with various arrester types and MPP trackers.
