Introduction
First, the MPPT effectiveness of most inverters manufactured today is quite high, providing 98 to nearly 100% of the energy available from the PV array. Second, MPPT effectiveness is very difficult to measure because it requires simultaneous measurements of dc-power into the inverter and the maximum power point (Pmp) of the PV array.
The inverter model, particularly when coupled with an accurate array performance model, provides significant improvements in the ability to analyze PV system performance, monitor inverter and array performance, and diagnose causes of system performance degradation.
