An electrolysis system has at least two electrolysis installations, a power supply source with a direct voltage output, and a central supply line connected to the direct voltage output. A direct current, at a first direct voltage, can be fed into the central supply line. The electrolysis installations are connected electrically in parallel to the central supply line. For a direct voltage supply from the public power grid a central voltage source converter converts an input-side alternating voltage into the output-side first direct voltage at a direct voltage output. Each electrolysis installation is connected via a DC/DC converter that converts the first direct voltage into a second direct voltage, parallel to the direct voltage output so that the second direct voltage drops across the electrolysis installation. Each of the DC/DC converters can be controlled and/or regulated for adapting a level of its second direct voltage.
