Data Storage
Event messages and instantaneous values are saved in the Sunny Island. This data can be evaluated and thus the
operating processes in the Sunny Island system can be traced. From this, for example, parameter settings can be
derived that will e.g. increase the self-consumption of PV energy or the service life of the battery. For SMA Service, this
data simplifies the analysis of any errors present and the identification of possible solutions.
The storage capacity of the inverter can be extended with the optional micro SD card. Thus, for example, data can be
recorded over longer time periods, enabling extended diagnostics possibilities to be used (see Section 16.14,
page 182).
Grid management services
The product is equipped with service functions for grid management.
Depending on the requirements of the grid operator, you can activate and configure the functions (e.g. active power
limitation) via operating parameters.
