Chae Han Lee Posted August 21 Share Posted August 21 Hello, Can I simulate mixed orientation in central inverter with one MPPT and mixed orientation in one string? A7-03 is one string with Orientation #1, A7-10 is one string with Orientation #2, A7-02 is one string with Orientation #1, #2 (Mixed orientation in one single string) Please, tell me how to simulate this project.

Michele Oliosi Posted August 21 Share Posted August 21 Dear Chae Han Lee, At the moment, it is not possible to simulate a mixed orientation in a single string. By the way, doesn't that cause important mismatch losses within the string? For the other cases (mixed orientation in a central inverter) that is possible, as long as each string has a given orientation. Link to comment Share on other sites More sharing options...
Chae Han Lee Posted August 22 Author Share Posted August 22 Dear @Michele Oliosi Thanks for reply to my question. Is it possible mixed orientation in a central inverter with one MPPT? Can you give me some information about how to give orientation each string? Link to comment Share on other sites More sharing options...
Michele Oliosi Posted August 22 Share Posted August 22 Yes, it is possible. In the sub-array with the central inverter, you should use the “Mixed #1 and #2” orientation. Then you can distribute strings using the slide bar at the bottom, or the tool “Orient distrib.”. For example (using the DEMO residential, and modified): Link to comment Share on other sites More sharing options...
Chae Han Lee Posted August 22 Author Share Posted August 22 Dear @Michele Oliosi Thanks for reply to my question again. If there are more than 3 orientations in single central inverter, do I have to simulate modify OND file with multiple MPPTs? like link below? I think if I modify central inverter's OND file with multi MPPTs, it is not diffrent from multi MPPT string inverter even if using power sharing. isn't it?

Michele Oliosi Posted August 22 Share Posted August 22 Yes, currently you can mix only two orientations, so indeed, if you have 3 orientations or more, you should artificially add MPPT inputs to your inverter. Link to comment Share on other sites More sharing options...
