Hello, I have worked on project which is tracker PV system. If I run the same simulation with same inputs in Version 7.4.8 and Version 8.0.3, there is a huge gape of Near shading loss value and Electrical loss value in both versions. I have attached the simulation results and shading diagrams for both version. Is there any bug in the software or due to update? Thank you

Hello, Is there any update that what is the reason behind getting different result value in version 7 and 8?

Hello, There is no bug in the multi-MPPT features. As I saw the video of Multi-MPPT and Power Sharing, It is just Workaround to share the different sizes of strings within the correct number of MPPT inputs and then everything seems to be fine. Thank you so much for sending me this video.

Hello, Good afternoon I am using PVsyst version 7.4.5 right now. Recently, I was working on a project capacity of 2008.55 kWp. It consisted of an East-West orientated PV system. I used the multi-MPPT feature to distribute the different sizes of strings. Having done the simulation, there was very high value of Inverter Loss over nominal inv. power (more than 2%). On the other hand, when I did not use the multi-MPPT feature and distributed the different sizes of strings within whole inverters, there was a very low value of inverter loss over nominal inv. power (-0.09%). Is there any bug in the software when it comes to using the multi-MPPT feature for the East-West PV System? Thank you
