摘要: In this paper, an innovative sensor suited to perform real-time measurements of operating voltage and current, open-circuit voltage, short-circuit current string-connected photovoltaic (PV) panels is presented. An effective disconnection system ensures that the does not affect behavior string during measurement phase offers many benefits like automatic detection bypass events; moreover, require additional cables thanks a wireless communication power supply section based on energy harvesting. extensive experimental campaign performed prove reliability usefulness for continuous monitoring PV plants. The capability detect faults accurately localize malfunctioning in highlighted.
