Decoded

Reports reverse polarity, unbalanced MPPT string connection; look at PV array; confirm with string polarity measurement; do: string polarity correction, string configuration correction.

What can be behind Reverse polarity

Failure modes that present as the reported condition, and the tests that tell them apart.

What can be behind Unbalanced MPPT string connection

Failure modes that present as the reported condition, and the tests that tell them apart.
