Pvfrance Posted October 13, 2023 Share Posted October 13, 2023 Dear all, I'm a beginner in pvSyst and I'm trying to find out how I can put a certain number of previously calculated modules on an inverter. I already know the configuration and distribution of strings and modules on each MPPT. Should I use the subarrays and Power Swing functionality? If so, what are the best practices for waiting for a specific number of modules? Thank you Link to comment Share on other sites More sharing options...
Lazare Fesnien Posted October 13, 2023 Share Posted October 13, 2023 Dear Pvfrance, When you have a different number of strings on the MPPT inputs, you should create one sub-array for each configuration (for example one sub-array for the MPPTs with a single string, and another one for the MPPTs with two strings). Then, in ‘power sharing’, you tell PVsyst which sub-arrays belong to the same inverter and how the power of the inputs is balanced. I have attached a PDF document to this e-mail with short examples on how to proceed. You can also find more information in the help under: ‘Project design > Grid-connected system definition > Multi-MPPT inverters’ ‘Project design > Grid-connected system definition > Multi-MPPT inverters: power sharing’ Link to comment Share on other sites More sharing options...
