Wet leakage current test system of photovoltaic module

Standard

  • IEC 61215: Terrestrial Photovoltaic (PV) Modules – Design Qualification and Type Approval
  • UL 61730: Safety Standard for Photovoltaic Modules
  • ISO 17025: General Requirements for the Competence of Testing and Calibration Laboratories
  • CE Certification(Conformité Européenne)

Product Advantages

  1. IEC 61215 Compliance
    • 22±3°C Temperature Control: Ensures consistent test conditions for wet insulation resistance measurements.
    • <3,500 Ω·cm Liquid Resistivity: Guarantees accurate leakage current detection per standard requirements.
  2. Multi-Directional Spray Simulation
    • 360° Adjustable Nozzles: Replicates rain, dew, and irrigation scenarios for PID testing.
    • Variable Flow Control: 0–10 bar pressure adjustment for customizable exposure intensity.
  3. Corrosion-Resistant Design
    • 15mm Plexiglass Tank: Withstands salt spray and UV exposure without degradation.
    • 316L Stainless Steel Fittings: Prevents electrolyte contamination during prolonged testing.
  4. Safety First
    • Ground Fault Interrupter (GFI): 30mA trip threshold for operator protection.
    • Door Interlock System: Halts testing if enclosure is opened during wet cycles.
  5. Smart Data Acquisition
    • 16-Bit Resolution ADC: Captures microamp-level leakage currents with 0.1% accuracy.
    • AI-Powered Diagnostics: Flags insulation defects and predicts PID degradation risks.

Product Features

  • Dual-Zone Temperature Control: Separate heating/cooling circuits for water and ambient air.
  • 7” Touchscreen HMI: Preloaded IEC 61215 test sequences with customizable hold times.
  • Remote Monitoring: Wi-Fi/Ethernet connectivity with SMS/ alerts for anomalies.
  • Self-Cleaning System: Automated tank drainage and nozzle flushing protocols.
  • Modular Design: Expandable from single-module to 10-module parallel testing.
