K24 Posted August 5, 2019 Report Share Posted August 5, 2019 Hello, I have a general technical question; is it ok to connect 2 strings with different modules number to one MPPT (18 and 19 for example when using the polystring feature in PV sol). I've read on some forums that there are losses due the voltage mismatch and the MPPT tracks the string with the lowest performance; but is it really a red line for PV designers or it's just not preferable and I can do it only when necessary? Thanks in advance Karam 1 Quote Link to comment Share on other sites More sharing options...
