The Sunny Island 5048 SMA Solar Technology AG
14 SI5048-TB-TEN110340 Technical Description
The anti-islanding procedure is required in order to ensure that, in case of a power distribution grid
failure or generator failure, the Sunny Island reliably prevents possible reverse voltages in these
power supply units. In case of a power distribution grid failure, Sunny Island disconnects from the grid
and continues supplying the the loads.
The Sunny Island can be integrated into different system constellations. The following graphics show
the Sunny Island's system components and the different wiring options (single-phase / single-phase
parallel and three-phase).
