Research direction

Start by opening the attached SAM_2126.zip in SAM 2025.4.16 or later and running all cases. Compare the inputs and outputs for one and two subarrays, then trace whether tracking, subarrays, or MPPT inputs cause the discrepancy; done when equivalent cases produce the same results.
