8.5 SMA Grid Guard
SMA Grid Guard is a security concept for country-specific settings in the inverter which determine the
grid behavior within a utility grid. These settings (SMA Grid Guard parameters) are dependent on the
country standard configured in the inverter and can only be configured with the SMA Grid Guard
code.
In order to change SMA Grid Guard parameters, you will not only need to be logged in as Installer,
but you will also need your personal SMA Grid Guard code which can be obtained from
SMA Solar Technology AG. You can find the relevant application from the download area at
www.SMA-Solar.com.
Entering the SMA Grid Guard Code
Requirement:
☐ You must be logged into Sunny Explorer in the user group Installer.

the grid operator.
