5.7 Setting the Grid 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.
5.7.1 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 product (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.
5.7.2 Setting Stand-alone Grid Operation
To operate the inverter in an off-grid system with Sunny Island, you must set the inverter via the
"Default" parameter to stand-alone grid operation ("OFF-Grid").
You have several possibilities to set the inverter to stand-alone grid operation:
• Setting via Sunny WebBox
or
• Setting via Sunny Data Control or Sunny Explorer
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 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 grid operator.
DANGER!
Danger to life due to high voltages in the event of outage of the power
distribution grid.
If you set the inverter to stand-alone grid operation, it does not fulfill any country-specific
standards and guidelines. If there is a power distribution grid outage, there is consequently
a danger of back-feed.
• Never operate the inverter directly on the power distribution grid when set to
stand-alone grid operation.
