A method for controlling operation of a power supply system (10) for supplying electrical power to a power consuming device (17), the power supply system comprising a climate-dependent source (5, 6) of electrical energy, an auxiliary source (7) of electrical energy, and an energy storage device (14) in electrical connection with the sources of electrical energy for storing electrical energy generated thereby, at least the climate-dependent source and the energy storage device being connectable to the power consuming device (17) for supplying electrical energy thereto. The method comprises the steps of acquiring (101 ) power consumption data indicative of an expected future power consumption of the power consuming device (17), energy storage data indicative of a current energy storage level of the energy storage device (14), and power supply data indicative of a current supply of electrical power from the climate-dependent source (5, 6) of electrical energy; supplying (105), if insufficient power is available from the climate-dependent source, electrical power from the energy storage device (14) to the power consuming device (17); and determining (102), based on the acquired power consumption data, energy storage data and power supply data, an energy storage threshold level at which electrical energy should be supplied to the energy storage device (14) to enable operation of the power consuming device (17). |
