6.5 Interface for External Communication
The communication interface is used to communicate with SMA communication devices
(e.g. Sunny Boy Control, Sunny WebBox) or a PC with appropriate software (e.g.
Sunny Data Control). Depending on the selected communication interface, up to 50
inverters can be interconnected. Detailed information on this topic can be found in the
communication device manual, the software, or on the Internet at
The following communication interfaces can be integrated into the Sunny Island 5048:
•
RS232
•
RS485
The detailed wiring diagram for the individual communication interfaces can be found
in the communication device manual. This wiring diagram includes:
•
Details on the required cable type
•
Which of the inverter's connections are used
•
Whether or not the communication cables must be terminated
•
Whether the protective earth needs to be connected to the cable shield
The next pages will describe the following:
•
The housing feed-throughs for the communication interface
•
The permitted cable route in the Sunny Island 5048
•
The location of the sockets for connecting the communication wires
•
The location of the interface port
6.5.1 Connection of the Interface
Installation or replacement of the communication interface is only to be
carried out by a trained electrician.
Communication via Powerline/Powerline modem (NLM) is not possible in stand-
alone grids.
When opening the Sunny Island 5048, follow all the safety instructions as
described in section 3.2 "Potential Hazards" (Page 24).
