A method for optimum matching of the voltage from a solar generator to a parallel-connected battery in different operating conditions. A DC/DC voltage converter (chopper) which produces the optimum matching is arranged between the solar generator and the battery. In order to reduce the power losses caused by the DC/DC voltage converter and in order to avoid such losses at the time of year when it is cold and when the battery voltage is low, the voltage of the solar generator is matched precisely to the battery at low temperature and hence at the maximum voltage produced by the solar generator and when the battery is partially discharged and the battery voltage is in consequence relatively low. The DC/DC voltage converter is used only to increase the voltage of the solar generator and is switched on only when, as a result of the prevailing operating conditions, an increase in the voltage provided by the solar generator is necessary for optimum matching. <IMAGE>
