In the inverter selection window I combine two or more different roof areas in the tree. Mark both by using the Control (Ctrl) key and the left mouse button as recommended. Afterwards the icon "Configure selected module Areas together" is activated. I do click the icon and both areas will be merged.

When selecting a suitable inverter, there I can select only one inverter, no number of inverters offered, no copying, incresing no. of inverters, adding inverters offered. So I cannot complete the configuration. How can we fix this problem?

Hello rui,

 

It is right. If you combine to different module areas to configure them to an inverter with multiple MPP trackers then you have to find one inverter wich matches the number of modules.

 

If you need more than one inverter you have to arrange the moduel areas or modules in advance.

 

In the 3D planning you have to select all modules which should be configured on one inverter in the module configuration window. This can be done with your mouse and if necessary the CTRL key. After you have selected the modules, right click on them and choose "Add to Group Module Ares Dialog". You have to do this for the different roofs. If you have add all needed modules to groups please use the button "Group module areas for the configuration" (3rd icon from the left). In the appearing window you should now have different module groups with different orientations or tilt angles. Select the groups which should be configured. You can also merge gropus if needed. Afterwards select "Configure" and the inverter selection window will open. Here you have to do the steps which you have described and select your inverter.

 

In the 2D planning you have to divide your module areas into "sub" areas. For Example: you have to module areas with 40 modules. You want to configure all the 40 modules module of one area and 20 modules of the other to one inverter. You have to divide one of the module areas into two module areas with 20 modules. Now you can select the area with 40 modules and one of the areas with 20 modules, combine them and choose an inverter.

 

Best regards

Hi,

just a short update: In the meanwhile we fully overhauled the design and simulation of PV plants with varying module areas. You can now build any configuration you want with the new 'Polystring feature'. For example:

• Two module areas on one MPP tracker
• Different module types in one string
• Parallel connection of strings with different number of modules
• etc etc

It is available in PV*SOL premium 2018.

Hello,

 

I have seen the update but I'm also not able to add an inverter that would have a different arrange of strings when combining more than one area. Could you tell me if there is a solution to this?

 

Thanks,

Hello Jamie,

At the moment you can only have one inverter type if you combine multiple module areas. The Polystring option only offers more options for configuring the strings.

Kind regards,

Marcel
