Abstract: DIAGNOSTIC SYSTEM AND METHOD FOR PHOTOVOLTAIC ARRAYS ABSTRACT Disclosed is a diagnostic system (100) and a method (200) for photovoltaic arrays. The system (100) comprises a load module (103) including an Insulated-Gate Bipolar Transistor, a string-switching module (102), including a plurality of relays, each of which is connected to an electronic controller module (106) configured to activate the Insulated-Gate Bipolar Transistor by sending a pulse width modulated signal thereto, a supervisory control and data acquisition module (107) coupled to the electronic controller module (106), a current sensor (104) and a voltage sensor (105) to measure the values of current and voltage for the string, and a cloud-based interface (108) coupled to the electronic controller module (106) to receive the data therefrom. The system (100) and the method (200) identify the causes of the underperformance of PV arrays and facilitate remote triggering of IV tracing operations at prescheduled intervals or on-demand, improving maintenance efficiency.
