A grid-connected PV array consisting of sixteen150-W modules can be arranged in a number of series and parallel combinations

Q3) A grid-connected PV array consisting of sixteen 150-W modules can be arranged in a number of series and parallel combinations: (16S, 1P), (8S, 2P), (4S, 4P), (2S, 8P), (1S, 16P). The array delivers power to a 2500-W inverter. The key characteristics of modules and inverter are given below. INVERTER Maximum AC power Input voltage range for MPP 250 V-550 Maximum input voltage Maximum input current MODULE Rated power Pdc. STC 150 W Voltage at MPP Open-circuit voltage43.4 V Current at MPP Short-circuit current 2500 W 34 V 600 V 11 Amp 4.40 A 4.8A Using the input voltage range of the inverter maximum power point tracker and the maximum input voltage of the inverter as design constraints, what series/parallel combination of modules would best match the PVs to the inverter? Check the result to see whether the inverter maximum input current is satisfied. For this simple check, you don't need to worry about temperatures.
