Once the correct grid code is selected and saved, the software automatically relocks the parameters upon exiting to maintain system security.
A: The grid code password is not about ownership; it's about regulatory compliance. Utility companies require that grid-interactive inverters cannot have their safety parameters altered by unauthorized individuals. This protects the stability of the public grid for all users.
The only safe, legal, and officially supported methods to obtain the password are: grid code password victron
detection and anti-islanding protections. Incorrect settings can be dangerous or illegal depending on local regulations. How to Get It : You must contact your local Victron dealer or distributor

| Issue | Solution | |---|---| | | This error means the selected grid code conflicts with your physical wiring or grid conditions. The correct remedy is to contact your distributor for the password to select a different grid code, not to attempt to bypass the protection | | Cannot change grid code after UK G98 selection | G98 limits inverter output to 3.69kW per phase. The password is required to upgrade to G99 for higher output limits | | Resetting to factory defaults does not clear grid code | This is by design. The grid code lock persists through factory resets to prevent accidental deregulation | | "Settings locked for access level" message | You are in User access mode. Navigate to Settings → General → Access and Security → Access Level and select "User and Installer". For older GX devices, the default access password is "ZZZ" (all capitals) |
