Sale

The I‑V 400w is a rugged, field-ready I‑V curve tracer and IVCK tester designed for PV module and string testing up to 1000 VDC and 15 ADC. It measures the full I‑V characteristic, along with solar irradiance and module temperature, and compares results to manufacturer-rated performance at standard test conditions (STC) to provide immediate "OK / NO" pass/fail feedback.

Key Functions

  • Captures I‑V curves and identifies key working parameters (Voc, Isc, Impp, Vmpp, Pmax)

  • Measures solar irradiance via reference cell, and module temperature using optional PT1000 probe and inclinometer

  • Compares measurements with a database of 30,000+ PV module types, user-updatable via onboard interface or PC software 

  • Displays both numerical and graphical I‑V curves and gives visual test status (OK/NO) instantly 

  • Supports remote operation with optional SOLAR‑02 wireless unit for decentralized irradiation/temperature logging (~1 m RF range) 

  • Connectivity via optical/USB port and Wi‑Fi for data export and remote diagnostics
