      PV Array Insulation Resistance Detection

      IRD300

      Ground Fault Detection

      The IRD300 PV array insulation resistance detection (also called earth fault detection) satisfies the need for detecting abnormal PV array (open-circuit voltage range: 60-300V) insulation resistance to ground, with high compatibility to work with non-isolated solar charge controllers. When abnormal PV array insulation resistance to ground is detected, the fault indicator will be presented by means of 1) the alarm indicator light on the device, 2) fault reminder sent via RS485 communication, or 3) an alarm relay output.
