André Mermoud Posted February 8 Share Posted February 8 If you have 2 cables of 240 mm², you can indeed choose 500 mm² in the box. The red values indicate that the cable section is "slightly" undersized with respect to the norms. PVsyst doesn't allow to use too undersized cables. NB: If you want to really define 480 mm² instead of 500, you can do this correction by increasing the cable length, in order to get the same Resistance.
