Technical Description
15 Sunny Boy in the Island Grid System
The following section provides information for configuring the Sunny Boy inverter in island grid
systems. The Sunny Island works with various inverters fromt the SMA Solar Technology AG.
15.1 Setting the Stand-alone Grid 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 an integrated "Power adjustment via
frequency" system (see section 15.2 "Frequency Shift Power Control (FSPC)" (Page 156)).
To activate this adjustment, you must configure the Sunny Boy as follows:
Sunny Boy with Stand-Alone Grid Parameters
As soon as you set the Sunny Boy to stand-alone grid parameters, the device no longer
complies with the DIN VDE 0126-1-1 and it is not allowed to operate connected to the
public grid directly.
Access Permission
For changing the grid relevant parameters in the Sunny Boy inverter you need a special
access code, the installer code. Contact the Sunny Island Hotline at the phone number
+49 561 9522 399 or by e-mail at SunnyIsland.Service@SMA.de to obtain this
personal code.
Required Communication Accessories
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 for data transfer (SMA
order number: "USBPBS-11" USB service interface)
•
Sunny Boy Control
•
Sunny WebBox
Additional information on communication can be found in section 7.5 "Communication"
(Page 53).
