Sunny Boy
SMA Solar Technology AG

SBU2200-TEN083320
Technical Description
1. Establish a communication connection with the Sunny Boy.
2. Navigate to the parameter settings.
3. Set the "Default" parameter to "Offgrid" (stand-alone grid).
The "OffGrid" parameter setting automatically sets the following Sunny Boy parameters to the values
below:
This completes the stand-alone grid parameter settings for the Sunny Boy.

DANGER!
Risk of lethal electric shock.
Risk of feedback if the public grid is down.
• Never operate the Sunny Boy directly on the grid using these settings.
• Only run the Sunny Boys in the Sunny Backup System S using the Automatic Switch
Box S connections specifically provided for this purpose (see section 8.2.2 „PV
System (X2/PV System)“ (75)).
Using the communication bus
If a Sunny Boy and Sunny Backup 2200 are operated together on a communication bus,
the "270.06 ComBaud" parameter in the Sunny Backup 2200 must be set to "1200"
(default).
The Sunny Backup 2200 only communicates through the SMA-Net protocol; Sunny-Net is
not supported.
