| 摘要 |
The invention relates to a photovoltaic system having: an energy storage device for generating a supply voltage at output terminals of the energy storage device, which has at least one parallel-connected energy supply line with one or more energy storage modules connected in series in the energy supply line, each module comprising an energy storage cell module with at least one energy storage cell and a coupling device with a plurality of coupling elements which is designed to selectively connect the energy storage cell module to the respective energy supply line or to bypass the same in the respective energy supply line; a photovoltaic module with one or more photovoltaic cells which is coupled directly to the output terminals of the energy storage device; and a control device which is coupled to the energy storage device and is designed to control the coupling devices of the energy storage modules for adjusting a supply voltage on the basis of the current flow into the one or more photovoltaic cells at the output terminals of the energy storage device. |
