Requirements for Battery Inverter Grounding Cable

  • Conductor type: copper wire

  • External diameter: 18 mm

  • Conductor cross-section: 4 mm² to 16 mm²

  • Sheath stripping length: 250 mm

  • The cable must be dimensioned in accordance with the local and national directives for the dimensioning of cables. The requirements for the minimum wire size derive from these directives. 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).
