Abstract: An inverter system for a photovoltaic panel includes: an inverter adapted for transforming a DC voltage from the photovoltaic panel into an AC voltage to be supplied to an electrical grid; a DC link interconnected with the inverter and providing a positive DC link output connectable to a positive pole of the photovoltaic panel and a negative DC link output connectable to a negative pole of the photovoltaic panel; a switch for disconnecting the negative pole of the photovoltaic panel from the DC link; and a controller for controlling the inverter and the switch; wherein the controller is adapted for opening the switch, such that the photovoltaic panel is solely supplyable by the positive DC link output.
