AC cable requirements

  • Conductor type: copper wire (flexible)

  • External diameter: 14 mm to 25 mm

  • Conductor cross-section: from 1.5 mm2 to 10 mm2

  • Insulation stripping length: 12 mm

  • Sheath stripping length: 80 mm to 90 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).

  • Recommendation: Use a cable with the marking H07
