<p>The protective device (100) for a photovoltaic system comprises at least one input (101, 102) for connecting to a photovoltaic generator (1) and at least one output (103, 104) for delivering electrical power supplied by the photovoltaic generator (1). The protective device (100) is characterised in that it comprises a detector for a signal supplied via the at least one output (103, 104) and is arranged so as to provide a low voltage (Us) of limited magnitude at the at least one output (103, 104) if a supplied signal does not meet predetermined criteria, and to connect the at least one output (103, 104) via a switching element (110) at low resistance to the at least one input (101, 102) if the supplied signal meets the predetermined criteria.</p> |
