Abstract
An electrical power supply apparatus has at least one electrical load connection to which an electrical load can be connected. A first electrical power supply connection can be connected to a mains supply network. A second electrical power supply connection is connected to an autonomous electrical power supply, such as a photovoltaic system. A switching apparatus switches the connection of the at least one electrical load connection to the first electrical power supply connection in mains operation or to the second electrical power supply connection in island operation. In order to improve the energy management during island operation, the at least one electrical load connection has at least one associated evaluation and control apparatus, which identifies the island operation of the electrical power supply apparatus and switches the at least one electrical load connection on or off, at least during island operation, as a function of preset criteria.
