This setting can be carried out if the entire small wind turbine system consists of 3 inverters only
and the asymmetric load is to be limited to 4.6 kVA in case of failure.
– If one of the 3 inverters indicates a line voltage fault or a device fault and stops feeding
in, the other two inverters automatically limit their power to 4.6 kVA.
5.5.2 Cabling
Cable Requirements
To connect the SMA Power Balancer, use a "LiYCY" cable with the following structure:
• Indoors: LiYCY 2 x 2 x 0.25
• Outdoors: Li-2YCYv 2 x 2 x 0.25
Differing asymmetric load limit for Italy
In inverters configured to country standard DK 5940, the asymmetric load is limited to
6 kVA.
