5 Extending the cable

If you must bridge large spans between two Sunny Mini Centrals, you can extend the SMA Power
Balancer cable.

Use an "LiYCY" cable for this with the illustrated layout:

Indoors: Li-2YCY 1x2x0.25 mm²

Outdoors: Li-2YCYv 1x2x0.25 mm²

Proceed as follows:

1.

Cut the SMA Power Balancer cable in the middle.

2.

Connect the wires and shield inside a junction box (outdoors) with an extension
cable 1:1 (max. cable length 300 m)

.

3.

Connect the SMA Power Balancer cable to the Sunny Mini Central as described in section 4
„Cabling” (Seite 17).
