Abstract (en)
[origin: EP2743442A1] The invention relates to an automatic roller blind (1), in particular for roof windows, comprising a curtain (15), a motor (2) driving the curtain (15), a rechargeable battery (6) to store energy required to operate the motor (2), a photovoltaic panel (4) charging said rechargeable battery (6), and a microcontroller (7) to control an operation of the blind in response to control signals including at least a control signal representing a sunlight level. The invention also relates to a method of controlling such an automatic roller blind. In order to make the blind virtually and fully autonomous, i.e. capable of continuous automatic operation for a relatively long period of time without an auxiliary power supply or frequent battery (6) recharge sessions, said control signal representing a sunlight level is an output electrical power of the photovoltaic panel (4), and the microcontroller (7) controls the operation of the blind also on the basis of the output voltage of said rechargeable battery (6).
