1. A method for transmitting data via direct current lines for energy transmission from a first communication unit to a second communication unit, comprising:
generating a high-frequency signal having a predefined voltage amplitude by the second communication unit and coupling the generated high-frequency signal onto the direct current lines using the second communication unit;
sensing a current level caused by the high-frequency signal on the direct current lines by the first communication unit;
determining a voltage amplitude for a high-frequency data signal based on the sensed current level caused by the high-frequency signal using the first communication unit; and
coupling the high-frequency data signal having the determined voltage amplitude onto the direct current lines by the first communication unit for the purpose of transmitting data to the second communication unit.
