Abstract
Controllable change-over apparatus for a solar module comprises an output terminal, a DC/DC converter, a controllable switching device and a control. The controllable switching device is implemented with a first switch position and a second switch position, wherein, in the first switch position, a power output of the solar module is connected to the output terminal via the DC/DC converter, and, in the second switch position, the power output of the solar module is connected to the output terminal by bypassing the DC/DC converter. The control switches the controllable switching device by using a performance characteristic for switching the same to the first or second switch position. In particular, the control is implemented to connect the solar module directly to its output terminal in the case of high power dissipation of the same, i.e. at strong solar radiation, and to connect the solar module to the output terminal via the DC/DC converter in the case of weak power dissipation of the same, i.e. during shading, which significantly increases the efficiency compared to a fixed connection of the solar module.
