Abstract: A controllable system for shutting down the connection between photovoltaic panels is provided. A connector with the function described in the present invention is arranged on a current transmission line between two photovoltaic panels adjacent to each other. A signal processing system, a power supply system, a control circuit, and an electronic switch element are arranged in the connector. The signal generator inputs a signal into the current transmission line, and the signal processing system separates the signal. A part of the signal continues to be transmitted along the current transmission line to other connectors on the current transmission line, and the other part of the signal is divided into a control signal and a power supply signal. The control signal passes through the control circuit and controls the electronic switch element to be turned on or off.
