In other news, SMA is a preferred supplier in a revolutionary 12MW ground-mounted solar PV project in Gardessen, Germany, complemented by a 4 MW/8 MWh battery storage system. With innovative technology, including three SMA Medium Voltage Power Stations (MVPS), SMA Power Plant Manager and ten SMA DC-DC converters, this project is creating a future-proof energy supply.
Starting in spring, sheep will once again take care of the grass beneath the PV modules, keeping the vegetation neatly trimmed.
Gardessen is already the fourth project by Green Energy 3000 featuring TESVOLT AG batteries and SMA components, following Großschirma (Saxony), Maulbeerwalde (Brandenburg), and Schnaittenbach (Bavaria). These hybrid plants bring additional storage capacity to the grid, contributing to the transformation of the energy system in Germany
