Sensorless fault-detection method for rooftop, large-scale solar Turkish researchers have developed an algorithm to distinguish faults and changes in PV plant output. The sensorless method only uses electrical data gathered from the DC inputs of inverters. They tested it on 8.5 MW of ground-mount PV at nine sites, as well as 8.2 MW across 18 rooftops.Scientists from Turkey's Dokuz Eylul University and Turkish EPC contractor Entegro Enerji Sistemleri have developed a new fault-detection method for large-scale PV plants. They said it works "smoothly" for both small and large PV systems. They also claimed that it improved operations and maintenance by distinguishing ... Den vollständigen Artikel lesen ...
