A system for controlling photovoltaic electricity production equipment having photovoltaic modules each equipped with a DC/DC microconverter connected to a DC bus, a DC bus manager, and an inverter for converting the direct current from the photovoltaic panels into alternative current intended for an electrical distribution network. Power is injected into the DC bus when the voltage of the DC bus is less than a minimum voltage until the minimum voltage is reached. Each of the microconverters injects a maximum power from the photovoltaic modules into the DC bus when the voltage of the DC bus is between a first voltage and a second voltage. The injecting of power from the photovoltaic modules into the DC bus is stopped when the voltage of the DC bus is less than a low threshold voltage or greater than a high threshold voltage.

Secure control mechanism for distributed photovoltaic system

The probe comprises at least one optic fiber and an electronic circuit comprising a securing device for securing the optic fiber in optic connection with signal conversion means. The electronic circuit comprises a removable electrical connector connected to the signal conversion means such as a light-emitting diode and/or photo-detector to supply or receive electronic signals used by a processing circuit. A measuring device comprises at least one optic fiber probe connected by means of the removable connector to a processing circuit. Application in particular to temperature measurement probes and devices which comprise optic fibers and to installations comprising electrical conductors.
