Wire Length in Ohmic Losses

[NaK]

Dear PVsyst Team,

 

I would like to clarify the wire length definition used in PVsyst.

Could you please confirm whether the following wire length inputs should be entered as **one-way length** or **two-way length**?

1. DC Circuit: String module connections / Main box to inverter  
2. AC Circuit: Length Inverter to injection  

Thank you very much for your support.

 

Best Regards,

NaK
