Controllable switching device for solar module, has control provided to control controllable switching unit to switch switching unit in one of switch conditions using output of solar module or input at output terminal

摘要

The device (100) has an output terminal (102), a direct current-to direct current (DC/DC)-converter (105), and a controllable switching unit (103) with two switch conditions, where an output (110) of a solar module (101) is connected to the terminal via the DC/DC-converter in one of the switch condition. The output is connected to the terminal through the DC/DC-converter in other switch condition. A control (104) controls the switching unit to switch the switching unit in one of the switch conditions using the output of the solar module or an input (111) at the terminal. Independent claims are also included for the following: (1) a method for controlling a controllable switching device for a solar module (2) a computer program with program code for implementing a method for controlling a controllable switching device for a solar module when the program runs in a computer.
