AC cable requirements
The cable must be dimensioned in accordance with the local and national directives for the
dimensioning of cables. The requirements for the minimum conductor cross-section derive from these
directives. Influencing factors for cable dimensioning are, among others, the following: nominal AC
current, type of cable, cable length, routing method, cable bundling, ambient temperature and
maximum desired line losses.

A neutral conductor must be connected to the inverter in either grid situation.
Only use solid wire or stranded wire
• Do not use fine-wire strands.
Ambient temperature
The higher the ambient temperature, the higher the power losses.
• Use cables with large cable cross-sections in installation sites with high ambient
temperatures.
Routing method
The cables heat up during operation. If there are several cables in a conduit, the temperature
of all cables increases.
• Use cables with a large cross-section if you lay several cables in one conduit.
