5.6 Setting the Mains and Country Parameters
A detailed description of the operating parameters for the inverter is available in the download area
at www.SMA.de/en in the category "Technical Description" of the respective inverter.
5.6.1 Setting the Installation Country
Using the "Default" parameter, you can set the installation country and/or the mains connection
standard valid for the country via a communication device (e.g., Sunny WebBox) or a PC with
corresponding software (e.g., Sunny Data Control or Sunny Explorer). This, however, is only required
if the inverter was originally ordered for another country. You can see the standard to which the
inverter was set upon delivery on the type label and on the included supplementary sheet with the
default settings.
5.6.2 Setting Stand-alone Mains Operation
To operate the inverter in a stand-alone mains system with Sunny Island, you must set the "Default"
parameter to stand-alone mains ("OFF-Grid") operation.
You have several possibilities to set the inverter to stand-alone mains operation:
• Setting via Sunny WebBox
or
• Setting via Sunny Data Control or Sunny Explorer
Changing mains-relevant and country parameters
To change mains-relevant parameters, you need a personal access code – the so-called
SMA Grid Guard code. The application form for the personal access code is available in
the download area at www.SMA.de/en, in the "Certificate" category of the respective
inverter.
Ensure that you discuss the changes to these parameters with your network operator.
DANGER!
Danger to life due to high voltages in the event of outage of the
power distribution mains
If you set the inverter to stand-alone mains operation, it does not fulfill any country-specific
standards and guidelines. Therefore, in the event of power distribution mains outage, there
is a danger of backfeed.
• Never operate the inverter directly on the power distribution mains when set to
stand-alone mains operation.
