Live Webinar: Multichannel IV Curve Tracing with the PV Master 70

Solar plants rarely fail loudly. A degrading bypass diode, a string quietly losing output to PID, a handful of cells mismatched against their neighbours are the kinds of faults that chip away at yield for months before anyone notices a problem on the balance sheet. The inspection methods most teams reach for can catch some of this, but they take time most teams don’t have to spare.

In this focused 25-minute webinar, we will walk through how multichannel IV curve tracing closes that gap: what it actually reveals about a plant’s health, and what changes when a measurement covers up to 20 strings at once, or up to 28 with the PV Master 70. Learn how to take the diagnostic process that might otherwise take days closer to minutes.

The right measurement technology makes all the difference here — and we’ll show you what that looks like in practice. As always, there’ll be time at the end to ask questions and discuss your specific measurement technology challenges directly.

What You’ll Learn

You’ll get a sense of how IV curve interpretation actually works in practice as you trace up to 28 strings in one go: what a healthy curve looks like under standard test conditions, and how specific deviations point back to specific causes, from a voltage drop suggesting a broken bypass diode to a stepped curve indicating partial shading.

And you’ll come away with a clearer picture of where this fits into a maintenance workflow — whether that’s a one-off commissioning check, an annual compliance measurement under IEC 62446-2, or an ongoing way to compare a “golden string” against the rest of the array and quantify exactly what cleaning or repair work would be worth.

Learn more about the PV Master 10 and PV Master 70 in the meantime

The webinar will draw on real measurement data from NEO’s PV Master series, built to be the most versatile diagnostic system for solar power plants on the market. Both the PV Master 10 and PV Master 70 trace IV curves up to 1500V and 40A with 0.05% accuracy, and both run the full diagnostic suite — performance and efficiency per IEC 62446-2, leakage detection with distance-to-fault localisation, and automatic fault classification — directly on site!

Where they differ is scale and setting. The PV Master 10 is the mobile, handheld instrument for fieldwork, expandable up to 20 strings simultaneously. The PV Master 70 is the case-based, modular version built for larger sites, scaling from 1 up to 28 channels and supporting the latest high-efficiency cell technologies — N-type, P-type, HJT, TOPCON — with under 1% accuracy at the MPP point. Both finish a measurement cycle by generating a complete, customisable PDF report within seconds.
