AC cable requirements

• Conductor type: aluminum or copper wire

• The conductors must be solid, stranded or fine-stranded. When using fine-stranded wire, bootlace ferrules must be used.

• Conductor cross-section: 16 mm² to 95 mm²

• External diameter: 35 mm to 48 mm

• Insulation stripping length: 30 mm

• Sheath stripping length: ≤ 375 mm

• The cable and conductor cross-sections must always be dimensioned according to the local and national directives and within the range specified by the manufacturer (SMA Solar Technology AG)." If the manufacturer (SMA Solar Technology AG) requires a higher conductor cross-section than the standard, the range of the manufacturer must be observed. Examples of factors influencing cable dimensioning are: nominal AC current, type of cable, routing method, cable bundling, ambient temperature and maximum desired line losses (for calculation of line losses, see the design software "Sunny Design" from software version 2.0 at www.SMA-Solar.com).
