March 1, 20224 yr Hello I have 2 different strings. This can be connected to MPTT 1,as shown in the drawing? I will connect the new MPTT 2 panels so that their performance will be the same. Thanks in advance. Greetings Antal

Any reason why you want to parallel them on one MPPT? Please see the photo below, same applies to what you are trying to do
March 1, 20224 yr Author Thanks for the answer. I know this, it was just this old system with 2 separate types of inverters & panels. Then I have to remove some panels to have the same voltage. MPPT 2 I install new identical panels. That's how it should be, so the difference between VDC and W is so small that even a shadow makes such a difference. Or I think wrong?
March 8, 20224 yr Author Hi This can be a problem if one wire is longer than the other? I can't solve it any other way. Greetings Antal
