1. An energy store, comprising:
- at least one interface by which charge is provided to locally connected power consumption devices and by which charge is provided to and received from a power grid, wherein the energy store receives and stores charge from a photovoltaic system; and
a control device that;
measures an actual state of charge of the energy store;
in a first capacity range of the energy store, transfers energy only between the energy store and the power grid;
in a second capacity range of the energy store, transfers energy from the energy store to the locally connected power consumption devices and transfers energy between the energy store and the power grid; and
in a third capacity range of the energy store, transfers energy only between the energy store and the power grid, wherein the first capacity range, the second capacity range and the third capacity range are mutually exclusive, wherein;
the first capacity range is between a first level and a second level,the second capacity range is below a third level and above the second level,the third capacity range is below a fourth level and above the third level, andeach of the first, second, and third capacity ranges corresponds to a respective state of charge of the energy store.
