How to detect PV system underperformance using only AC-side inverter data

An Australian research team has developed a five-step, rule-based method that detects and classifies underperformance in PV systems using only AC-side inverter data. Validated across more than 1,000 systems, the approach offers a low-cost, low-intervention solution for improving reliability, fault response, and PV system performance.A research group from Australia has developed a novel rule-based method for detecting and classifying underperformance in PV systems, using only inverter data from the alternating current (AC) side. The method was validated using more than 1,000 PV systems across Australia, ...
