Device for an energy generation unit of a user's installation, which is connected to an energy supply network and to at least one energy consumption unit of the user's installation and comprises a programmable logic control which controls an internal energy consumption, by the energy consumption units of the user's installation, of the energy generated by the energy generation unit.

Method and device for managing energy consumption of energy generated from a renewable resource

The invention relates to a method and an apparatus for performing a switching operation with the aid of a operation element (). In order to avoid mechanical components, at least one light-emitting diode () is used as the operating element (), and the voltage (U) on the at least one light-emitting diode () is measured in the switched-off state, and the switching operation is performed when the measured voltage () falls below a pregiven lower threshold () over a pregiven time period ().

Method and apparatus for carrying out a switching process using an operating element including at least one light-emitting diode as a display and a device for measuring the voltage of same
