Connection socket, solar panel, use and method for generating a pre-defined current

The box (7) has actuators (13a-13c) i.e. direct current regulators, electrically connected to a regulating device (17). One of the actuators is supplied with electrical input current at a given time, where the input current is converted into a time variable output current at the device such that a predetermined super-positioned output current is generated at connection terminals (15a, 15b). The other actuator is supplied with electrical input voltage that is converted into a time variable output voltage at the device such that super-positioned output voltage is generated at the terminals. Independent claims are also included for the following: (1) a solar panel comprising a solar module (2) a method for generating a predetermined output current or a predetermined output voltage.
