Many thanks 'Littleharbor2' -
When connecting strings in parallel you want to keep voltage as close as possible so, yes, you want to have equal panel count.Leave a comment:

Parallel String size affecting MPPT output
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.
