  1. Your inverter is not defined as allowing work with a cos phi. To resolve this you must modify the OND file from the database
  2. Dear Nikoloz, This comes from the PAN file, can you send it to us at support@pvsyst.com ? Regards
  3. We update the database using the requests of the manufacturers, and publish it with each new release of PVsyst. We can't of course follow all the new products of all manufacturers in the world. We don't want to include data without the acknowledgement of the manufacturer. 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: https://www.youtube.com/c/PVsystTutos, page Component database

  12. The speed of the simulation mainly depends on the complexity of the system and the complexity of the 3D scene you are trying to simulate. Here are a couple of ideas: In the 3D scene: When near shadings are used, the calculation of the shading factor basically requires to compare each elementary surface to each PV table (goes with the square of the number of elements) You can simplify the calculation by using arrays of tables instead of single PV tables if your tables are well aligned; The shading calculation with trees is very slow, as each face of each tree has to be calculated independently. For tree arrays, you are advised to use a single parallelepiped; A significant time may also be due to the pre-calculations for the optimization of the shading factor calculation, or the check that each table should not interpenetrate any other table or objects. Try to avoid interpenetrating objects; Too much detail in the topography will lead to long import and simulation durations and possibly slows down the user interface. There is a limit of 500โ€™000 unique points when importing topography data through a CSV file, and a maximum of 1โ€™000โ€™000 triangles when the triangulation is performed. In the ground data details, you can use the simplification tool to reduce the number of points. System definition: You can simplify the definition of the system if you have defined many sub-arrays with a single inverter. This will make the simulation very slow, and it is best to group identical inverters in the same sub-arrays; Using the multi-MPPT feature will slow down the calculation. If possible, you can disable it, which means considering inverters as a whole; With string inverters, the simulation is performed for each inverter input, which significantly increases the simulation time. Shadings calculation: When using the โ€œModule Layoutโ€ for electrical mismatch effects, defining more than 1โ€™000 - 1โ€™500 modules leads to extremely long calculation times; You can simplify the shadings calculation by using "According to module strings", and if necessary the "Fast (table)" option, instead of "Detailed electrical calculation (acc. to module layout)". The shadings calculation will be less accurate but it should be much faster. Here is the link to the help page that explains how to set up partitioning: https://www.pvsyst.com/help/index.html?shadings_partitioninstrings.htm In the slow case, at each simulation step the shading factor is recomputed.
  13. Dear Berthiaud, The SolarEdge architecture obeys very strict rules, established by SolarEdge. PVsyst strictly applies these rules. These rules namely define the compatibility conditions between the optimizer and the inverter models, , as well as some maximum sizing and operating limits. Please ask the SolarEdge team.

  15. Dear Pvfrance, When you have a different number of strings on the MPPT inputs, you should create one sub-array for each configuration (for example one sub-array for the MPPTs with a single string, and another one for the MPPTs with two strings). Then, in โ€˜power sharingโ€™, you tell PVsyst which sub-arrays belong to the same inverter and how the power of the inputs is balanced. I have attached a PDF document to this e-mail with short examples on how to proceed. You can also find more information in the help under: โ€˜Project design > Grid-connected system definition > Multi-MPPT invertersโ€™ โ€˜Project design > Grid-connected system definition > Multi-MPPT inverters: power sharingโ€™
