Hi, I would like to ask if there is any way to put a different number of panels per string in 1 inverter? for example, I have a 30kW inverter with a total number of 54 panels, the only option that PVsyst has is 4 strings with 14 modules which are 56pcs of modules, is there any way I can configure it to 18,18,19? Thank you
