5.7 Setting the Grid and Country Parameters
Changing Grid-Relevant and Country Parameters
To change grid-relevant parameters, you need a personal access code - the so-called
SMA Grid Guard Code. The application form for the personal access code is located in
the download area at www.SMA.de/en, in the "Certificate" category for each inverter.
Ensure that you discuss the changes to these parameters with your electric power company.
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.
5.7.1 Setting the Installation Country
Using the "Default" parameter you can set the installation country and/or the grid 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 from the type plate and the supplementary document provided with the
factory settings.
5.7.2 Setting Off-Grid Operation
To operate the inverter in an off-grid system with Sunny Island, you must set the inverter via the
"Default" parameter to off-grid ("OFF-Grid") operation.
You have several possibilities to set the inverter to off-grid operation:
• Setting via Sunny WebBox
or
• Setting via Sunny Data Control or Sunny Explorer.
DANGER!
Danger to life due to high voltages in the event of outage of the power
distribution grid.
If you set the inverter to off-grid operation, it does not fulfill any country-specific standards
and regulations. Therefore, in the event of outage of the power distribution grid, there is a
danger of back feed.
• Never operate the inverter directly on the power distribution grid when set to off-grid
operation.
