Abstract
In order to be able to perform a shutdown test on an inverter with little expenditure, a trigger signal is modulated to the AC current or the AC voltage at a first moment, and the inverter is used at a second moment, which occurs a defined duration after the start of the trigger signal at the first moment, to generate an AC current or an AC voltage with a fault signal that is detected by the inverter and which triggers a shutdown of the inverter, and the shutdown moment of the AC current or the AC voltage is determined. A shutdown duration of the inverter is determined from the difference between the shutdown moment and the second moment.
