Electronic device (21) for controlling a solar panel (12) connectable, by means of an electrical power supply connection (23), to a control device (26, 26M) configured to send to the electrical connection (23) a control and supply signal (S OC ) modulated in frequency and/or amplitude, the electronic device (21) being configured to: detect the presence and absence of the control and supply signal (S OC ) on the electrical connection (23); electrically couple, in a first operating condition in which the control and supply signal is present on the electrical connection, the solar panel (12) to the electrical connection (23); and electrically decouple, in a second operating condition in which the control and supply signal is absent on the electrical connection, the solar panel (12) from the electrical connection. |
