ABSTRACT:
The object of the present invention is to provide a structure for the electrical protection of photovoltaic facilities in the event a photovoltaic generator (G1-Gp) is connected with its polarity reversed, for what it includes a protection cell that comprises two connection points (1, 2) at which the photovoltaic generator is connected (G1-Gp), at least one device (D) in charge of reducing the voltage of the photovoltaic generator (G1-Gp) in the event of polarity reversion, which is connected in parallel between the aforementioned two connection points, at least one element (M) of breakage and/or protection of the photovoltaic generator (G1-Gp) serially connected to the preceding elements, minimizing the loading on the aforementioned break and/or protection elements.
