I would like to connect the two roof surfaces to the same inverter. Module Array 01 and 02 to the same inverter. How do I do that?

And my next question is about the DC cable going out to the panels. When I enter a length of, for example, 30 m, how do I change it so that it is 2 × 30 m? Since there is a positive cable and a negative cable.

Dear Anders,

Thank you for your inquiry.

To connect both roof surfaces to the same inverter, click "Configure all unconfigured modules", select the two module areas using the Shift key and click "Configure module areas together":

On the "Cables" page, enter twice the DC cable length for each MPP tracker, e.g., 60 m (if the outbound and return paths are each 30 m). The circuit diagram will then display the double DC cable length in the form "2 x 30 m":

In the attached project, you may want to work with different lengths of positive and negative cables. To do this, use the "Cable Plan" page within the 3D environment. For example, if the inverter is located at the southern end of the building, add two cable grommets there, connect four strings to each grommet, and let the software calculate the exact DC cable lengths:

Press the F1 key to access the help page for cable dimensioning.

The project file we have processed is attached.
