Dimensioning of the grid supply cable
Select the cross-section of the AC grid supply cable in such a way that the cable
losses are kept as low as possible (max. possible cross-section, with min. cable
length).
The following table shows the maximum cable lengths in dependence on the
cable cross section. The maximum cable length should not be exceeded in order
to limit the ohmic voltage drop in the cable to < 1%.
