<p>The protective device (100) comprises an input (101) for connecting to a photovoltaic generator (1) and an output (103) for delivering electrical power supplied by photovoltaic generator. A detector detects a signal supplied via the output and provides a low voltage (Us) of limited magnitude at the output, if the supplied signal does not meet predetermined criteria. The output is connected to the input via a switching element (110), at low resistance, if the supplied signal meets the predetermined criteria. An independent claim is included for operating method of protective device of photovoltaic system.</p> |
