Via the control device 8, a corresponding control of the individual components, such as the input DC-DC converter 2 or the output DC-AC converter 4, in particular of the switching elements arranged therein, are made. In the control device 8, the individual control or control processes are stored for this purpose by appropriate software programs and / or data or characteristics.
- FIG. 2 shows an inverter 1 according to the invention, which is expanded with a memory DC-DC converter 9, to which an energy store 10 can optionally be connected.
- the inverter 1 in addition to the functionality of a grid-connected inverter 1 also fulfills the functionality of a so-called island inverter.
- an inverter 1 with these functionalities is called a hybrid inverter.
- the memory DC-DC converter 9 which is connected to the intermediate circuit 3.
- the input DC-DC converter 2 and / or the memory DC-DC converter 9 can supply the intermediate circuit 3, wherein the memory DC-DC converter

- the memory DC-DC converter 9 is activated and supplies the required additional energy to the intermediate circuit 3, so that the output DC-AC converter 4 can supply the consumers 7 with the corresponding energy. Should a consumer 7 be switched off or more energy supplied from the solar modules, the memory DC-DC converter 9 can be disabled again.
- the solar modules supply the consumers 7 completely with electrical energy. Thus, the energy storage 10 is conserved, whereby its durability is extended and a power failure can be bridged longer. If, for example, a consumer 7 is switched on, in turn energy can be taken from the energy store 10.
- the consumers 7 must be supplied entirely from the energy store 10.
- the input DC-DC converter 2 is deactivated and the memory DC-DC converter 9 supplies the intermediate circuit 3 and thus the output DC-AC converter 4, the consumers 7th
- the state of charge of the energy store 10 can also be monitored when it is removed from this energy. This ensures that the energy storage 10 is not completely discharged and recharging is possible. As a result, the energy storage 10 is spared and its durability extended.
