HT PV-ISOTEST: Essential Safety Tester for 1500V PV Systems

The HT PV-ISOTEST is a dedicated safety tester designed for verifying the insulation resistance and protective conductor continuity in photovoltaic installations up to 1500V DC. It meets the requirements of IEC/EN62446 and IEC/EN61557 for insulation and continuity testing, making it a core tool for commissioning and maintenance of solar PV systems.

Comprehensive Insulation Testing

Ensure the integrity of your DC circuits with multiple test modes, as detailed in the product datasheet:

  • Test Voltages: Selectable 250V, 500V, 1000V, and 1500V DC to suit various system requirements.
  • DUAL Mode: Measures insulation resistance between positive/negative conductors and earth simultaneously.
  • TIMER Mode: Performs a timed insulation test (3s to 999s) for specific diagnostic procedures or testing unearthed metal masses.
  • High Resistance Range: Measures insulation resistance up to 100 MΩ.

Ground Fault Locator (GFL) Function

A standout feature for efficient troubleshooting:

  • Pinpoint Faults: The GFL function helps locate the position of a low insulation fault within a single string (disconnected from the inverter and earth connections).
  • Reduces Downtime: By identifying the approximate location of the fault (accuracy ±1 module according to the datasheet), technicians can target repairs more effectively, saving time and reducing system downtime which impacts returns associated with different energy tariffs.
  • Conditions: Requires specific test conditions, including Vtest ≥ Vnom and a single fault < 0.23 MΩ, for optimal results.

Continuity of Protective Conductors (RPE)

Verify the effectiveness of your earthing system:

  • IEC/EN62446 Compliant: Performs continuity tests with a test current >200mA DC, as required by the standard.
  • Wide Range: Measures continuity resistance from 0.00Ω up to 1999Ω.
  • Cable Compensation: Although not explicitly stated for this model in the provided datasheet snippet, similar testers often include cable resistance compensation for accurate low-ohm readings (verify in full manual if needed).
