SMA Solar Technology AG
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:
No. Parameter
1 I-NiTest
2 Uac-Min
3 Uac-Max
4 Fac-delta-
Lower range, where the Sunny Boy is active,
based on f
0
5 Fac-max+
Upper range, where the Sunny Boy is active,
based on f
0
6 dFac-Max
max. rate of change
7 Fac-start delta
frequency increase in relation to f
point the power adjustment via frequency begins
8 Fac-Limit delta
Frequency increase in relation to f
point the power adjustment via frequency ends.
The power of the Sunny Boy here is 0 W.
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!
