If your design has more than four (4) strings/branches per inverter and/or more than two (2) inverters, and/or uses a microinverter with three (3) or more inputs a single line diagram cannot be generated.

You can reduce the number of strings or inverters in the system builder, then re-specify the BOS components to generate your permit package with the SLD.

Note: When using micro-inverters the same four (4) branch limit applies to the array, meaning you can configure one array with up to four (4) branches, or two (2) arrays with up to four (4) branches each, for a total of eight (8) branches.
