13.2 Setting Sunny Boy Parameters
Controlled battery charging is needed in a stand-alone grid. Sunny Boy inverters can
reduce their feed-in power for this reason. This task is performed by a "Power
adjustment via frequency" system (see section 13.3 "Frequency Shift Power Control
(FSPC)" (Page 120)).
To activate this adjustment, you must configure the Sunny Boy as follows:
1. Establish communication with the Sunny Boy.
2. Go to the parameter settings that are relevant to the type of communication
system.
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:
If you use the Sunny Boys with offgrid parameters in the public
utility grid, the inverter no longer meets the requirements of DIN
VDE 0126-1-1. Please observe all regionally relevant regulations
or discuss this with the local electricity supply company
responsible.
For changing the grid relevant parameters in the Sunny Boy inverter you need
a special access code, the installer code. Contact the Sunny Boy hotline
(telephone +49 561 9522 499), to obtain this personal code.
To set the parameters, a communication channel to the Sunny Boy is required.
Install one of these three variants:
• PC/laptop with Sunny Data software and a service cable (see section 2.6
"Accessories (optional)" (S. 17))
• Sunny Boy Control
• Sunny WebBox
Section 15 "Communication Interface" (Page 123) provides comprehensive
information on these variants and the components they require.
