Battery data cable requirements

Battery data cable for the connection between the SMA Home Storage and Sunny Tripower Smart Energy

For the connection between the SMA Home Storage and Sunny Tripower Smart Energy, a pre-assembled battery communication cable must be used (SMA order number: HS-COM-CBL-3-10). This battery data cable has an RJ45 and a COM connector.

A commercially available network cable can be used as a battery data cable. The cable length and quality do affect the quality of the signal. Observe the following cable requirements:

  • Cable category: minimum CAT5e

  • Plug type: RJ45 of Cat5, Cat5e or higher and without integrated locking lever protection

  • Shielding: SF/UTP, S/UTP, SF/FTP or S/FTP

  • Maximum cable length between 2 nodes when using patch cables: 50 m

  • UV-resistant for outdoor use
