SMA Solar Technology AG Sunny Boy in the Island Grid System
Technical Description SI2012_2224-TEN082311 155
1. Establish communication with the Sunny Boy.
2. Go to the parameter settings.
3. Set the parameter "Default" to "Off-Grid" (stand-alone grid).
The "Off-Grid" parameter setting automatically sets the following Sunny Boy parameters to the
following values:
This completes the stand-alone grid parameter settings for the Sunny Boy.

WARNING!
Risk of lethal electric shock!
If there is an outage of the public grid there is the danger of feeding back into it
• Never operate your Sunny Backup system directly on the grid with these settings!
