Sma Operation - SMA Sunny Island SIC50-MPT Installation Manual

SMA Solar Technology AG
6.6.3 SMA Operation
The communication between the charge controller and the Sunny Island 5048/2012/2224 allows
the charge controller to be controlled in a coordinated manner. This ensures precise calculation of the
state of charge in the Sunny Island without an additional battery current measuring shunt.
All important operating data of the charge controller can be read on the Sunny Island display. In
addition, the most important values are saved on the Sunny Island SD card.
Up to four charge controllers can be connected in parallel to one Sunny Island system.
