What should I consider when planning large systems with multiple inverters?

For inverter configuration, it is recommended to divide large systems into subsystems, for example, one subsystem per building, per building section, or per inverter. If you need to add or delete modules later, you only need to delete the inverter configuration for the relevant subsystem, not the entire system.

To maintain the inverter numbering, we recommend using the "Define Module Areas for Configuration" function. Detailed instructions with screenshots can be found in this article. First, define which modules should be configured together. Select the desired modules of the first module area, right-click on the selected modules, and choose "Add to 'Define Module Areas' Dialog." Repeat this for all module areas belonging to the same inverter/subsystem. (To access a different building, use the drop-down menu in the top menu bar.) Then, click "Configure" and configure Inverter 1/Subsystem 1. Repeat these steps for each subsystem/inverter. Subsequently, subsystems 1 to x have a fixed inverter assignment 1 to x. The inverter numbering is transferred to the string diagram and remains unchanged even if minor subsequent modifications are made to one of the configurations.
