hcapdevi Posted February 11, 2022 Share Posted February 11, 2022 Hello,I am testing different inverter on the same project to make a choice. I am testing an inverter from the brand Kaco with only one MPPT. I don’t know how to, or if it is even possible, to create a system with different string’s length on a same MPPT. Since I only have one MPPT I can’t use the multi mppt function. Kaco is telling me that the mismatching losses of such a configuration (different number of modules in parallel string on a single mppt), is balanced with the better efficiency), but I would like to see that myself on PVsyst.Does anyone can help me?

Lazare Fesnien Posted February 11, 2022 Share Posted February 11, 2022 Hi, The only way is to re-define your inverter as 2-MPPT inputs, and define one sub-array per kind of modules. By the way the mismatch between strings of different but close voltages is completely negligible. You can have a look on our tool "Detailed Losses > Module quality – LID – Mismatch > String voltage mismatch, strings study". And on the Help "Project design > Array and system losses > Array mismatch losses". Link to comment Share on other sites More sharing options...
