Why doesn't my permit package include a single-line diagram?

Wondering why an SLD was not included in your permit package?

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

You can reduce the number of strings or inverters in the Electrical Design then finish the project 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.
