2.2 Diagnosis and Communication
The modular PV system technology leads to a spread out distribution of the Sunny Boy
String inverters. A simple and fast function monitoring of the status and measured val-
ues for each single Sunny Boy can be achieved with only a few system components.
The data collected is either displayed on the LCD of the Sunny Boy Control or is shown
on the screen of a PC running the according SMA software. Two programs “Sunny
Data“ and “Sunny Data Control“ are based on a comfortable Windows GUI and allow
the user to process the data with other programs such as MS Excel.
The signal transmission between the PC and the single inverters is normally done via
Powerline communication (see chapter 6.1). The Sunny Boy String Inverters support the
following monitoring concepts developed by SMA:
•
PC with Sunny Data for Windows for small and medium size PV-plants, also
with Sunny Boy Control.
•
Sunny Boy Control as stand-alone controller for any PV-plant size.
•
PC with Sunny Data Control for Windows together with a Sunny Boy Control.
Communication based on one of the above concepts supports the following func-
tions:
•
Continuous acquisition of operation data of all connected Sunny Boys.
•
Supervision of operating states and failure indication.
•
Spot value transmission from one or several selected Sunny Boys.
•
Identification of failures in the single strings.
•
Graphical representation of the data from single Sunny Boys or comparison of
the data of several ones.
•
Modification of operation parameters to optimise the entire plant.
