Electronic circuit for a photovoltaic module and method for switching in a photovoltaic module

An electronic circuit for a photovoltaic, PV, module, comprising:

• PV terminals for coupling to the PV module;
• and string terminals for coupling to a PV string;
• a current path running between the PV terminals and the string terminals, which current path is configured to conduct an electric current generated in the PV module in a first current flow direction to the PV string;
• a disconnector arranged between a first terminal of the PV terminals and a second terminal of the string terminals, which disconnector is configured to interrupt the current path in a first state along the first current flow direction;
• and to close the current path in a second state along the first current flow direction;
• a controller, which is configured to acquire current flow information about a current flow in at least one sub-portion of the current path along a second current flow direction opposite to the first current flow direction;
• and to control the disconnector from the first state into the second state based on the current flow information.
