Technical Description
16.2 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 a "Power
adjustment via frequency" system (see section 16.3 "Frequency Shift Power Control
(FSPC)" (Page 119)).
To activate this adjustment, you must configure the Sunny Boy as follows:
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:
As soon as you set the Sunny Boy to use stand-alone grid parameters, the
device no longer meets the requirements of DIN VDE 0126-1-1. Observe
all regionally relevant regulations and 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 Island Hotline at the
phone 49 561 95 22 399 and by e-mail at
SunnyIsland.hotline@SMA.de 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 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 6.5 "Interface
for External Communication" (Page 51).
When you order Sunny Boys for a stand-alone grid, they are already
programmed with the stand-alone grid settings at the factory. No other changes
are required.
