5 Upgrading your Sunny Boy
Like all inverters of the Sunny Boy family, the Sunny Boy 2800i
can be equipped with different communication interfaces. The
operator can see operating values and failure messages in detail
and can process them on a PC with the software tools provided
by SMA free of charge.
In addition the installer can easily adjust the Sunny Boy 2800i to
specific conditions (e. g. too high grid impedance or PV modules
not based on silicon cells).
Currently there are three ways to transmit data:
• via the grid cable (PLC = Power-Line-Communication)
• via a seperate cable with RS485 signals
• via a seperate cable with RS232 signals
For continous data acquisition SMA Regelsysteme GmbH
developed the data logger Sunny Boy Control. All values
recorded can be visualized on a four-line LCD. A convenient and
complete data acquisition system can be established by coupling
Sunny Boy Control to a PC that you only need to switch on
occasionally.
At the moment there are three different versions of the Sunny Boy
Control:
• Sunny Boy Control Light
Simple data acquisition and reduced measurement data sto-
rage with PV plants consisting of up to 20 Sunny Boys
• Sunny Boy Control
Data acquisition for plants with up to 50 Sunny Boys, long
term data storage
• Sunny Boy Control Plus
Fully compatible with Sunny Boy Control with analog and
digital ports for enhanced data acquisition with external
sensors
