ISOMETER® isoPV1685 Series
- Application photovoltaic systems up to DC 1500 V
- Separately adjustable response values 200 Ω…1 MΩ
- Automatic adaptation to the system leakage capacitance up to 2000 μF
- Interface selectable RS-485 or Modbus
The device is used for insulation and residual current monitoring of large photovoltaic systems up to 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 against ground exist due to interference suppression methods. Adaptation to system-related high leakage capacitances also occurs automatically. The device generates locating current pulses required for ground-fault location. That allows the localization of the ground fault using permanently installed or mobile ground-fault locators. Integrated ground-fault monitoring allows fast signalling of a measured ground faults on the AC side (inverter, transformer).
