hcapdevi Posted August 10, 2022 Share Posted August 10, 2022 I am used to using the power sharing function, but this time it is not working. I define my sub arrays I use the power sharing function (everything works fine) I start the simulation, but the power sharing is not taken into account, and it is not saved after the simulation is done. Is this a bug or a miss used of myself? Thank you for your help ? Link to comment Share on other sites More sharing options...

hcapdevi Posted August 11, 2022 Author Share Posted August 11, 2022 I do normally select it (just not here on the screenshot), it has not effect unfortunately. Link to comment Share on other sites More sharing options...
Bruno Wittmer Posted August 11, 2022 Share Posted August 11, 2022 This looks indeed strange. The definitions are all correct, but it seems that the information was not propagated to the variant. I have not seen this before, would it be possible to export this project and send it to support@pvsyst.com, so that we can check why this is happening?

hcapdevi Posted August 11, 2022 Author Share Posted August 11, 2022 Yes of course, can you explain the procedure? What file do you need? Link to comment Share on other sites More sharing options...
taahxr Posted August 18, 2022 Share Posted August 18, 2022 (edited) I have been having the same issue. While doing the Power Sharing in the SYSTEM Tab, - all seems fine. But after running the simulation the PNOM reverts back to the "non-powering sharing" value. See my screenshots below From my experience, it seems to only happen when more than one inverter type is used.

hcapdevi Posted August 18, 2022 Author Share Posted August 18, 2022 "From my experience, it seems to only happen when more than one inverter type is used." No, in my case, I'm using two 100KTL and the problème is the same. Link to comment Share on other sites More sharing options...

To export the project, please go to 'Files-> Export projects' in the main window. Select the project and click on 'Export'. This will create a single file with .zip extension, that you can e-mail to us. Link to comment Share on other sites More sharing options...
Awie Botes Posted August 23, 2022 Share Posted August 23, 2022 Hi everyone, I am having a similar solution (where the Pnom values change) when using the Huawei 60 kW and 100 kW KTL's. Is there maybe an update on the problem? Link to comment Share on other sites More sharing options...
hcapdevi Posted August 23, 2022 Author Share Posted August 23, 2022 Hello, PVsyst is working on it As soon as the problem is fixed I will post it here Link to comment Share on other sites More sharing options...

Awie Botes Posted August 25, 2022 Share Posted August 25, 2022 Hi, I don't know if this has been stated yet, but the problem only occurs when I use two different inverters. For example a 100 KTL and 60KTL. Is there maybe an update from your side? Link to comment Share on other sites More sharing options...

hcapdevi Posted August 31, 2022 Author Share Posted August 31, 2022 Hello, Awie Botes : no the problem the problem occurs even with two same inverters (two 100 KTL) taahxr : no updates for now, the PVsyst 7.2.18 does not solve the problem. I will let you know. Link to comment Share on other sites More sharing options...
Bruno Wittmer Posted September 1, 2022 Share Posted September 1, 2022 The source of the problem has been identified. We did not handle correctly all cases when you add or remove sub-arrays to a system that is already configured for power sharing. As a consequence, it is possible to end up with some of the sub-arrays that are included in the power sharing configurations, but which are not flagged as using power sharing. The power sharing configurations of these sub-arrays will be reset when starting the simulation. As a workaround, you can uncheck and check again the box at the top of the power sharing configuration: This will force all flags in the sub-arrays to their correct state, and the problem will be gone. We will secure the code such that these inconsistent states cannot happen any more. Link to comment Share on other sites More sharing options...
Zeira Alford Posted September 6, 2022 Share Posted September 6, 2022 Hi, I got another bug that it always remain error message even if the number of MPPT inputs is a multiple of the number of inverters. So I cannot click OK for that. Link to comment Share on other sites More sharing options...
Manuel Maier Posted December 20, 2022 Share Posted December 20, 2022 @PVsyst forum Dear PVsyst-Team, is there any update on Zeira Alford's problem? I am facing the same issue. Thank you! Link to comment Share on other sites More sharing options...
