6.1 Data Transmission via Powerline
Signal transmission between the Sunny Boy and the Sunny Boy Control or the PC is
done with the grid connection via Powerline. This requires a minimum of installation
(see Fig. 6.1: Example of data transmission via Powerline’). The Sunny Boy must be
equipped with a Powerline modem for data transmission. The PC must be equipped
with the socket modem (SWR-COM). This is already integrated in the Sunny Boy
Control, the specific controller for PV-plants. The PC or the Sunny Boy Control can
be positioned anywhere within the in-house network as they acquire data directly
from the AC circuit.
For trouble-free operation the Sunny Boys and the PC socket modem or the Sunny
Boy Control must be connected to the same phase of the in-house network. If the
communicating partners are connected to different phases the communication must
be established with a so-called phase coupling device. The phase coupling device is
available from SMA and must be installed by qualified personnel. It will make com-
munication within the entire in-house network possible.
