Multi-Channel IV-Curve Tracer

The NEO PV Master products ensure quick and reliable inspection and evaluation of solar plants including a fully-automatic AI based system diagnostic. Up to 24 input channels with a rating of up to 1600V DC together with the smart IV-curve diagnostic function allows simultaneous evaluation of multiple PV strings and complete PV arrays.

WORLD’s first and most powerful solar power plant diagnostic system.

FAULT DETECTION

  • Mismatch Losses

  • Hotspots

  • PID (Potential induced degradation)

  • Bypass diode defect

  • Cell Crack

  • Soiling & Glass breakage

  • Delamination & Discoloration

  • and a lot more

4. AUTOMATIC DIAGNOSTIC

The patented diagnostic system automatically shows the condition of each string. Different colours outlines the string performance and shows different PV module faults.

Fault detection: Mismatch, PID, Hotspot, Bypass diode breakage,  Shading, Soiling, Glass breakage, Delamination, Cell Crack etc.

…. PV inspection was never faster and easier

… no other technology gives as much details as the smart diagnosis function

How Not To – Out-dated Measurement Approach

Analysing the effects of Supraharmonics asks for Power Quality Analyzer that cover a frequency range up to 500 kHz. Classical PQ Analyzers present problems because of their limited bandwidth. Typically they can measure up to the 50th Harmonics (2.5kHz), but cannot detect higher emissions of voltage and currents. By design, they are not able to be used in the troubleshooting process at all.

How To – Troubleshooting with the PQA 8000

In this Application Note, we outline the complexity and shortcomings of traditional measurement approaches we often see out in the field. Fortunately, all these problems do not concern engineers with the appropriate measurement equipment. Our customers appreciate the PQA8000H in troubleshooting Supraharmonic emissions, where its strengths really come into play ..
