System configuration

The following table shows the possible system configurations for the inverter types:

*not SB 11000TLUS-12

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.

SB xxxxTLUS-10 ✓ ‒

SB xxxxTLUS-12 ✓ * ✓

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.
