SAFETY DEVICE FOR PHOTOVOLTAIC PLANTS

摘要

A safety device for photovoltaic plants comprises a disconnecting unit (20), which can be actuated by a remote control so as to electrically disconnect a photovoltaic panel (10) from the string of panels it belongs to, and a control device (60) that periodically checks the correct operation" of each photovoltaic panel (10); in the · absence of a signal (Z) of correct operation coming from a photovoltaic panel, the safety device electrically disconnects the photovoltaic panel from the remainder of the plant.
