To start, open the Build System menu. After we have our first inverter set up in a way that we like (e.g. however many branches and strings we need), click on the "Create New Array" option on the left side of the page.
Once we select this option, the tool will automatically add an array with the same module selection, and an adjustable inverter selection.
If we need to add any additional inverters, we can repeat the same steps as above (i.e. set up the new array how we like, and then use the "Create New Array" option again).
Continue to build your system and perhaps (re)arrange modules to fine-tune the array layout. Then, we'll want to specify the mechanical & balance of system components being used.
