Patent ID: 7969700

Claim:
An electrical system for protecting a photovoltaic system, the electrical system being provided for preventing damage in the photovoltaic system in an event of a reverse connection of a photovoltaic generator inside a photovoltaic field, the electrical system comprising a protection cell, wherein the protection cell includes: two connection points at which the photovoltaic generator is connected; at least one device in charge of reducing a voltage of the photovoltaic generator in an event of a polarity reversion due to the reverse connection, the at least one device being connected in parallel between the two connection points at which the photovoltaic generator is connected; and at least one element of breakage and/or protection of the photovoltaic generator, the at least one element of breakage and/or protection being serially connected to the at least one device in charge of reducing the voltage of the photovoltaic generator and the two connection points at which the photovoltaic generator is connected.
