ISOMETER® isoPV1685DP

  • For large photovoltaic systems up to AC 1000 V / DC 1500 V
  • 2 Separately adjustable response values 200 Ω...200 kΩ
  • Automatic adaptation to the system leakage capacitance
    up to 4000 μF
  • Modbus RTU interface for connection to monitoring systems
  • User-friendly operation through integrated display

The device is used for insulation of large photovoltaic systems up to AC 1000 V/DC 1500 V designed as IT systems. The measurement method specially developed for slow voltage fluctuations (MPP tracking) monitors the insulation resistance even in systems equipped with large solar generator panels where extremely high system leakage capacitances up to 4000 µF against earth exist due to interference suppression methods.
