Hello, I have specific issue. I have two roofs with PV modules (75pcs + 24pcs) and 3 inverters (33pcs per inverter). Two of them are on roof 1, third one on roof 2 which uses 24 modules and other 9 on roof 1. On third one polystring configuration is used. The issue occurs when I try to allocate modules manually. I can do it for some modules but then after allocation of 5x 11 strings on roof 1, the other modules are freezed and unable to select/allocate them. What can I do? Additionally, module counting seems not to work properly. Matija

Dear admins, I have a question regarding performances of the system that I have created.  I manually set in the program which inverters will be used, the string lengths, and their connections to the MPP inputs. The system is functioning, and there are no errors, but I don’t know how to assess whether the system’s performance is satisfactory. If there are any parts with significant losses, or any problematic spots, considering that I configured everything manually, please tell me. Also, if you could point out the fields I should check when manually setting the inverter selection and string connections, I would appreciate it. Thank you in advance, Gordana
