Abstract

This paper describes a new advanced string monitoring box (ASMB) with a different measurement regime i.e, with or without its own system on chip (SoC) can identify the defective string instantly for a power loss of less than 0.1% of the sub-array that results in huge improvement in reliability and higher yields of solar photovoltaic (PV) power plants by reducing mean time to repair (MTTR) substantially. ASMBs and programmable data logger combine turns out to be a stand-alone, limited but effective back up to supervisory control and data acquisition (SCADA). Its capability to audit the performance of the inverter and SCADA combine is an excellent spin off with both sets of data monitored at remote monitoring console.
