Fraunhofer ISE Goes with Medium Voltage for Resource Efficiency in PV Plants
Press release from 19.06.2024
Enormous quantities of raw materials are required for the conversion of the energy system, for example, in the form of copper and aluminum cables to connect renewable generators to the grid. One promising approach to save raw materials is to move from the low to the medium-voltage level in renewable energy power plants. The Fraunhofer Institute for Solar Energy Systems ISE sees a huge potential for savings with higher system voltages, especially in large PV power plants. The institute is planning first pilot power plants with this technology and is aiming for a broad market launch together with industry. To kick-off its new research topic "Medium Voltage – A Resource-Efficient Way to Interconnect", Fraunhofer ISE will be presenting the world's first medium-voltage PV string inverter and a medium-voltage battery inverter at the Smarter E trade fair in Munich (June 19-21).
