  "textContent": "A method and device is provided for calibrating a time base signal in a photovoltaic inverter, which has a conversion circuit configured to convert a DC current into an AC current. The method comprises the steps of: receiving a reference signal by a receiving unit from an external reference signal source; determining a deviation between the received reference signal and a time base signal which is generated by a local time signal generator; correcting the generated time base signal to minimize the determined deviation or calculating a correction factor, wherein the calibration unit automatically corrects the time base signal obtained from the time signal generator, even when a reference signal is temporarily unavailable, depending on at least one operating parameter which is stored in a data memory and which is formed by an internal temperature inside the housing of the photovoltaic inverter and/or by a measured supply voltage; and adapting predetermined values for components of the conversion circuit depending on the corrected time base signal or depending on the calculated correction factor.",
