Connection requirements of the utility operator
Always observe the connection requirements of your utility operator!
Wire Design
The cable cross section should be sized using the "Sunny Design" design program
(www.SMA.de/en) so that output losses do not exceed 1 % at nominal power.
The maximum line length for each cable cross section is shown in the following table.
Cable cross section
10.0 mm²
16.0 mm²
Depending on the type of cable installation, observe the requirements of the following factors when
selecting the cable type / cable cross section:
• the ambient temperature
• the type of cable installation and
• the UV resistance.
Cut line losses in half
If three Sunny Mini Centrals with symmetrical feeding are combined to form a three-phase
system, the neutral conductor is not subjected to any load, and the line losses are halved.
Thus, the maximum possible cable length is doubled.
