2 s surge protection solution for solar energy has always been very active in creating products and solutions with low environmental impact and searching and developing new technologies, anticipating customer needs. Today, renewable energies play a fundamental role in future energy policy along with a more friendly impact on our environment. Solar energy, is with no doubt an energy source of huge potential, one that can be exploited without harming the environment. With its will to always offer the more efficient solution along with a safe and reliable protection to equipment, and its long experience in creating surge protective devices (SPs), has developed specific SPs, the OVR PV range. Thus with the OVR T1, the OVR T2 and the OVR T range, the OVR PV ensure the safety of your solar equipment.

3 specific OVR PV MOVs (Metal Oxyde Varistors) are mainly used in SPs Type 2, some Type 3 and in SPs designed for solar applications. Their quick response time gives a good protection to the equipment. However, they have a shorter life time than other technologies (like spark gap or gas tube used for the Type 1) and when they aging, they finish their life (EoL) in short circuit. When this occurs, it is very important to be able to disconnect the SP. Thus, every SP using MOVs must have an internal thermal disconnection. SP disconnection in normal condition Fast disconnection in progress specific backup protection (fuses or Ms) is also generally recommended. However, on PV networks due to low current and high voltages, it is much more difficult to disconnect the MOV of the SP in case of end of life in short circuit. Thanks to the specific disconnection of the OVR PV, with very quick response time and the isolation of the disconnection device from the MOV, OVR PV offer a very safe and reliable protection. disconnection completed and isolation from the MOV in end of life Solar energy Lightning and surge protective devices 3

The surge protective device depending on the environment should be installed in a leakproof casing. onnection to the earthing bar and to the ground of the inverter on the side should be as short and rectilinear as possible. The main features of the OVR PV range for surge protection of photovoltaic systems are: PV current withstand (Iscwpv) up to 100 without any backup protection, pluggable cartridges for easy maintenance, auxiliary contact with the "TS" option, "Y" configuration for a better protection, specific thermal disconnection for a safer protection. Protection of the inverter output on the side Routine installation onnection to the earthing bar and to the ground of the inverter on the side should be as short and rectilinear as possible. head protection at the entrance of the building Routine installation onnection to the earthing bar should be as short and rectilinear as possible.
