I-V Curves Explained | Basics of Current-Voltage Curves for Solar & DER Systems

In this DER Tech Talk, Will White, Solar Application Specialist at Fluke, explains the basics of an I-V curve — a foundational diagnostic tool in solar and distributed energy systems. What you’ll learn: – What is short-circuit current and open-circuit voltage – How an I-V curve tester works – What the maximum power point (MPP) reveals – Why I-V curves detect issues missed by standard measurements Whether you’re working with a single solar module or an entire string, understanding the I-V curve helps ensure accurate, efficient diagnostics. ➕ For more info, visit: https://www.fluke.com/en-us/search/fl... #Fluke #IVCurve #SolarDiagnostics #DistributedEnergy #DER #FlukeTools
