Parallel String size affecting MPPT output

[TJ119189]

Hello all,
My question is whether to match the number of panels in 2 strings (parallel) when connecting to the MPPT?
e.g.
1) Should I have 2 identical string sizes (8 + 8 parallel) when connecting to 1 MPPT?
2) Or can I have 1 string of 4 panels and 1 string of 12 panels (4 + 12 parallel) connected to 1 MPPT?

Would the output of the MPPT be affected?
TIA.

When connecting strings in parallel you want to keep voltage as close as possible so, yes, you want to have equal panel count.
