Dear Nikoloz, It seems that the inverter you want to use is a central inverter with only one MPPT. This means all strings connected to it must be identical. So, you don’t need to worry about the MPPT definition. In PVsyst, just select the configuration “PNom sharing within the inverter” (see below). Then, you only need to specify the number of inverters. Regards,

Dear Ishan, First of all, the Unlimited Tracker represents an idealized PV table layout, with all rows having exactly the same length. Most likely, your 3D scene doesn't follow this idealized representation. Could you please send us your project by email at support@pvsyst.com, so I can check it and explain why you're seeing these differences? Regards,

Dear Oli, Unbalanced inverters are not designed for power sharing. Regards,

Dear Arisk, Unfortenately, this is not possible. Regards,

Dear Ville, Unfortunately, with a central inverter in PVsyst, it's not possible to perform what you want to do. You can try to modify the OND file by allowing multiple MPPTs, but this will not reflect reality. Regards,

Dear Edwin, Thank you very much for your feedback and for taking the time to report this bug. Could you tell me how this situation occurred in your case, where the Medium Voltage panel remains visible even though you selected HV transformers? I need to reproduce this bug on my side in order to fix it. Regards,

Dear, I can’t help you with AutoCAD or how to convert the topography to a CSV file. Maybe just make sure to check the X, Y, Z coordinates in the CSV. With version 8, we can import topography from the internet — it might also be useful for you. Here’s how to do it: In Near Shading, click File > Import > Download a satellite ground image and/or ground data Then, don’t forget to check “Also import topography data” Regards,

Dear Cleyson, I created the PAN file based on the datasheet and didn’t get any error messages, see below: Click on the "Model parameters" tab and select the default value for series resistance, as shown below: Try using exactly the same settings and let me know if anything changes for you. Regards,

Dear, We update the database using the requests of the manufacturers, and publish it with each new issue of PVsyst. We can't of course follow all the new products of all manufacturers in the world. Therefore, please ask your provider/manufacturer to take contact with us for updating the database. Nevertheless you can easily create your own components by yourself. The easiest way is to choose a similar existing device in the database, modify its parameters according to the manufacturer's datasheets, and save it under a new name, therefore creating a new file in your database. You have a tutorial for that on youtube: Regards,

Dear Terence, Is it possible to send us the DAE file to "support@pvsyst.com" so we can also try it and check why there's a difference between the near shading and the report? Regards

Dear Andrés, I suggest grouping your PV array based on the electrical layout you have planned with the inverters. It can add complexity to your project, so if you have a varying base slope, it's better to use a single orientation. PVsyst has implemented a new tool to estimate the percentage of losses due to slope variation. Go to the Near Shadings > "Orientation Management", then click on the "Orientation Distribution Analysis" tab. Choose the plot type "Base slope deviation, absolute errors". In my example below, you can see a loss of -0.02% due to averaging the base slope into one orientation: Regards,

Dear Swonno, Can you explain what "origin feature in 3D scene" means? Also, could you share how you placed your PV tables and what type of tables you are using? In PVsyst, under Tools, there is an automatic altitude feature, but it works well only if all the tables are independent from each other. Regards,

Dear Johnny, First of all, in a self-consumption + storage system, the system responds to the user's load. So, if you have a small load profile and a large PV system, excess energy will be injected into the grid. Since I don’t know your exact goal, I suggest creating multiple variants — starting with fewer PV modules, then trying with higher storage capacity. This will give you different results and help you find the best configuration. Regards,

Dear Stewart, In the Near Shading tool, you need to draw your 3D scene manually — it is not generated automatically. I suggest watching our tutorial related to near shadings: Regards

Dear, See my example below on how to proceed: Click Orientation Management: Then, select the orientation you want to delete and delete it, as shown below: Regards,
