Abstract: A protection system configured to couple between a generator that has a number of partial strings and an inverter includes a control device, and a series-connection switching device configured to selectively connect the partial strings together in series. The system also includes a parallel-connection switching device configured to selectively connect the partial strings together in parallel, wherein the series-connection switching device is actuated by the control device such that it interrupts the series connection of the partial strings in case of a hazard, and the parallel-connection switching device is actuated by the control device such that it connects the partial strings together in parallel in case of a hazard.

Abstract: An inverter operable to interface with a generator that has a number of partial strings includes an inverter bridge circuit configured to connect to the partial strings, and a control device operably associated with the inverter bridge circuit. The inverter further includes a series-connection switching device configured to selectively connect the partial strings in series in response to a control signal from the control device such that the series-connection switching device interrupts the series connection of the partial strings in case of a hazard condition detected by the control device.
