Abstract:
1. A method of determining starting conditions of a solar converter in a photovoltaic system, the photovoltaic system including a photovoltaic panel system having one or more photovoltaic panels, the method comprising: determining an open circuit voltage of the photovoltaic panel system; determining beforehand limit values for the starting conditions, the limit values including an open circuit voltage value and a temperature value, with which values the solar converter is configured to be started; determining beforehand a temperature dependency of the open circuit voltage of the panel system; determining a temperature of the panel system; and setting a criterion for starting the converter, the criterion comprising determining, by using the determined temperature dependency and the determined limit values for the starting conditions, whether the determined temperature and the determined open circuit voltage enable the starting of the converter.
