Since the end of 2018, overvoltage protection has been mandatory for solar systems in Germany, as instances of overvoltage can damage solar systems and their peripherals. System operators, be they private or commercial, therefore protect their photovoltaic systems with overvoltage protection.
The KOSTAL PLENTICORE G3 inverter has an integrable DC overvoltage protection module, which protects your photovoltaic system from overvoltage damage on the DC side.
Overvoltage protection must be installed at the point of entry into the house. If the cable length from here to the device is more than 10 metres, additional protection equipment must be installed just upstream of or inside the device. Installation and material costs can be saved by using an integrable solution.
This allows DC overvoltages can to be detected immediately and effectively discharged. Overvoltage protection is particularly useful for PV systems to which a battery storage system, heat pump or other powerful consumers such as an electric vehicle are connected.
