Power converter module, photovoltaic system with converter module and method for operating a photovoltaic system

摘要

The invention relates to a converter module, in particular for coupling a direct current source to an alternating current network on the one hand and an electrical energy storage system on the other hand, with a direct voltage input connection, which is designed to receive an input voltage from a direct current source, an intermediate circuit, which is directly coupled to the direct voltage input connection, one DC voltage output connection, which is designed to provide a DC output voltage, an AC voltage output connection, which is designed to provide an AC output voltage, a DC voltage converter, which is coupled between the intermediate circuit and the DC voltage output connection for taking an input voltage from the intermediate circuit, an inverter, which is connected between the intermediate circuit and the AC voltage output connection is coupled for taking an input voltage from the intermediate circuit, and a control device, which is coupled to the DC voltage converter and the inverter, and which is designed to control the input voltage of the inverter and the DC voltage converter for maximum power consumption from the DC power source.
