Abstract
The invention relates to a safety device (20) for a photovoltaic system for feeding into a power supply system (50) comprising at least one input (21 22) for connection to a PV generator (10) and at least one output (23 24) for connection to an inverter (30) and comprises a switching element (29) for de energizing the at least one output (23 24). The safety device (20) is distinguished by the fact that it comprises an evaluating unit (27) which is arranged for switching the switching element (29) in dependence on a low frequency signal at the at least one output (23 24). The invention also relates to a method for operating such a safety device (20).
