When the temperature derate table is incorrectly formatted, clicking Update plot causes a callback error. It should display an error in a message box instead with a suggestion of how to fix the problem (incorrect number of rows or columns, etc.).

This is not a critical issue because SSC does catch the error.

To replicate:

1. Create a Detailed PV case with any financial model.
2. On the Inverter page, under Inverter Temperature Derate Curves at the bottom of the page, change Cols from 5 to 8.
3. Click Update plot.
