Abstract
The dynamic system is part of a dynamic apparatus having at least one photovoltaic generator, at least one battery and at least one device for controlling the dynamic apparatus. The method for controlling the dynamic system on the basis of sunlight involves electrically isolating the photovoltaic generator from the battery, reading the no-load voltage of the photovoltaic generator, determining a numerical value on the basis of the no load voltage, corresponding to the no-load voltage reading, and comparing the predetermined numerical value with at least one reference threshold value. When the predetermined numerical value corresponds to a value range limited by at least one such reference threshold value the dynamic system is controlled so as to thereon confer a configuration corresponding to the value range.

Abstract
The dynamic system is part of a dynamic apparatus having at least one photovoltaic generator, at least one battery and at least one device for controlling the dynamic apparatus. The method for controlling the dynamic system on the basis of sunlight involves electrically isolating the photovoltaic generator from the battery, reading the short circuit current of the isolated photovoltaic generator, determining a numerical value based on the short circuit current, said numerical value corresponding to the reading of the short circuit current, and comparing the numerical value determined with at least one reference threshold value. When the numerical value determined corresponds to a value range limited by at least one such reference threshold value, the dynamic system is controlled so as to thereon confer a configuration corresponding to the value range.

Abstract
A method for using a stand-alone system, provided with an actuator connected to a battery, comprises during a discharging phase of the battery at a predetermined current the measurement of a temperature representative of the battery temperature and the determination of a first voltage threshold depending upon the measured temperature. Then, a voltage is measured at the battery terminals. An operating mode, selected at least between a normal and deteriorated mode, is determined, said stand-alone system being in the normal operating mode when the measured voltage is higher than the first voltage threshold, and in the deteriorated operating mode when the measured voltage is lower that the first voltage threshold, the current provided by the battery during an actuation being reduced when going from the normal mode to the deteriorated mode.
