azein Posted December 4, 2018 Share Posted December 4, 2018 I'm having an issue simulating an inverter with 4 MPPTs. The thing is that they are unbalanced, while when "Unbalanced MPPT" option is ticked in "Additional Parameters/Secondary Parameters" of the inverter, only two MPPTs can be defined. Please let me know how to simulate such inverters? Link to comment Share on other sites More sharing options...
azein Posted January 10, 2019 Author Share Posted January 10, 2019 Should I conclude it's not yet possible to simulate such inverters? Link to comment Share on other sites More sharing options...
murali1802 Posted January 16, 2019 Share Posted January 16, 2019 I am facing the same problem. Unable to define an unbalanced inverter with 4 MPPTs. Can the PVsyst team help please? Link to comment Share on other sites More sharing options...
André Mermoud Posted February 15, 2019 Share Posted February 15, 2019 The "Unbalanced" feature is a very special mode, only available for 2 MPPT imputs with very dissymetric inputs. When you have more than 2 MPPT inputs, you cannot define this mode and its very specific behaviour. But you can always define Sub-arrays of different powers on each MPPT. In this case you should use the "Power sharing" option for attributing a given PNom to each MPPT input. See the help "Project design > Grid-connected system definition > Multi-MPPT inverters: power sharing" for further details. Link to comment Share on other sites More sharing options...
