SMA Grid Guard is a safety concept for country-specific settings in the inverter, determining the grid

and can only be changed with the SMA Grid Guard password. In order to change SMA Grid Guard
parameters, you will need to be logged in as an installer and you will need your personal SMA Grid
Guard password, which you can obtain from SMA. The application form for the personal access code
is available in the downloads area at www.SMA-Solar.com, in the "Certificate" category of the
respective inverter.

Information on password security
While you enter your password, the user interface of the Sunny WebBox displays
information on the security level of the password entered. The Sunny WebBox categorises
passwords as "very unsafe", "unsafe", "adequate", "safe" and "very safe". Only select
passwords with a security strength that is at least "safe".
Maximum number of upload attempts
If the data transmission from the Sunny WebBox to the Sunny Portal or external
FTP server fails, the Sunny WebBox will make further attempts to transmit the data.
The "Maximum number of upload attempts per time window" value specifies the number
of data transmission attempts the Sunny WebBox makes within the defined time window.
