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 optional Sunny Display integrated in the
front panel of the Sunny Boy or on the LCD of the Sunny Boy Control or 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 or print out 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: ‘Data Transmission via Powerline’). 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
•
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
•
When using a PC: graphical representation of the data from single Sunny Boys or
comparison of the data of several ones
•
Modification of operation parameters to optimize the entire plant
