  • Patent number: 9735777
    Abstract: A method is provided for safely switching off a photovoltaic module comprising solar cell groups, a first conductor electrically connected to the solar cell groups, and a second conductor electrically connected to the solar cell groups. The safety device comprises at least one first safely switching element and one second safety switching element, wherein the safety switching elements are arranged in parallel across the solar cell groups and are connected to the first conductor and the second conductor in an electrically conductive manner. If an error state occurs, at least one of the safety switching elements is switched by means of a switching process, such that a shorted circuit is produced across the solar cell groups. The at least two safety switching elements perform the switching process in working areas that differ at least partially regarding the temperature.
