String Cable Length

[Sondre207]

Hi,

On the length of the DC-cable, what does 2x Go-and-return means? 

Does the cables between panels count? And is it the length as cable 1 in my drawing, or 1+2?

Hello Sondre207,

since you chose to connect two strands onto an inverter which supports interconnecting MPPs, we have to expand your screenshot a bit further:

2x Go-and-return means that (in the example case above) the 17m get divided to 8.5m for each cable leading to the both module areas. The green color of the cable section corresponds to the graphic on top. Within the section DC topology per MPP tracker and String cables PV*SOL shows the interconnection of the MPP trackers.

I hope this helps to better understand.

Kind regards,
Frederik
