Abstract: A method is described for controlling an electronic device with a programmable control unit based upon a plurality of operative parameters and a series of rules that these operative parameters shall satisfy. The method includes the following steps: associating a firmware with the electronic device; providing the firmware with a file containing the values of the operative parameters and the rules these operative parameters shall satisfy; and controlling the device by using the operative parameters and the rules contained in the file.

Abstract: A method for managing an energy generation system is disclosed. The system includes a cluster of power generators connected by a connectivity network. Each power generator includes an inverter having a respective controller, and at least a data set available to the controller for controlling the respective power generator. Each inverter transmits through said connectivity network, to the other inverters of the cluster, information concerning said data set available to it, said information being sufficient to check whether the data sets available to each inverter are aligned. Each inverter receives, through said connectivity network, information concerning the data set available to other inverters of the cluster and checks whether the data set available to it is aligned with the data sets available to the other inverters of the cluster.
