Photovoltaic system without its own inverter at Fraunhofer ICT

Renewable energy company Baywa r.e. AG is installing a "technically very sophisticated, novel system combination of wind and solar energy, including battery storage, which is unique in this form in Europe" for the Fraunhofer Institute for Chemical Technology ICT in Pfinztal, Germany.
The 670-kilowatt solar power system, which consists of several partial module arrays on three roofs and an open area, does not have its own inverters, but receives its connection to the power grid via the existing wind power plant. In the concept, the solar and wind power systems and battery storage are connected to each other on the DC side and feed into the grid with one common inverter instead of several separate ones. This is intended to both increase efficiency and reduce costs.
