Product Advantage
PV disconnectors offer a multitude of advantages that make them indispensable components in photovoltaic (PV) systems. they prioritize safety, which is paramount in solar installations. These devices enable reliable isolation of PV arrays from the grid or other system parts during maintenance, repair, or emergency situations. By cutting (interrupting) the electrical circuit completely, they protect technicians from electric shocks and prevent equipment damage caused by unexpected current flow, adhering to strict international safety standards like IEC 62271-121.
