摘要： A method for controlling the power of a system, and a device for controlling the power of a system, the system having an electric energy source, electric consumers, an energy store, an inverter, and a charge controller, the system being connected via an interconnected power sensor to the in particular public AC electric power supply, and the power sensor may be used for ascertaining the power withdrawn by the system from the in particular public AC electric power supply, or for ascertaining a corresponding quantity, such as the active power withdrawn from the in particular public AC electric power supply, the sensor signal being transmitted to a controller which regulates the power withdrawn from the in particular public AC electric power supply toward zero by appropriate actuation of the inverter and the charge controller.

摘要： A charging system including an accumulator, a use of an MPP tracking method for charging an accumulator, and a method for charging an accumulator with the aid of a charging system, the charging system including a voltage source, a converter, and a rectifier, the current supplied and/or driven by the voltage source being supplied to the DC-voltage-side terminal of a converter, the converter having semiconductor switches, which are controllable in a pulse-width modulated manner, in order to generate an output-side AC voltage, the output-side AC voltage feeding a rectifier, whose output-side voltage, especially rectified voltage, functioning and/or acting as charging voltage for the accumulator, an arrangement for detecting the output current of the inverter being situated in the converter, the effective value of the output current in particular corresponding to the charge current of the converter, a current limiting arrangement of the converter limiting the output current of the inverter to a current value such that the charging power, i.e., the product of charging voltage and charge current, is controlled toward a maximum value.
