Multi RS change a second time Grid code setting

Hello users of the Multi RS,

When commissioning a Multi RS, I set the grid code to Germany. It now shows an error indicating that this setting is incorrect, and as a result, the grid relay does not switch on.

I now expect that I should have set it to Europe instead.

Coming from the MultiPlus-II, I was used to selecting Germany.

As already mentioned elsewhere, this setting can only be configured once.
Resetting to factory defaults unfortunately does not change this setting.

I am now unable to change the grid code, as it appears a password is required?

Is this correct? And should I now request this password from the supplier (NKON)?
Or are there any other ways to change this setting?

Yes do this.
Although i don’t see much difference in the grid code tolerances? So maybe you do need to trouble shoot a bit

I agree with you, it seems to be a different issue.
I have a 3-phase connection, with one Multi RS connected to Phase 3.

In the system settings, I can choose between Standalone or 3-phase (Left/Right).
When I activate 3-phase Right, an error occurs and the grid relay is disconnected.

#75 Network not properly configured
3-phase operation is not yet certified in combination with the selected grid code.

The Multi RS is connected via a Cerbo GX and is also equipped with a VM-3P75CT.
The latest firmware updates were done today.

Is it already possible to operate in a 3-phase network with only one Multi RS?

One mutli rs connected to grid and rest inverting?

Or a three phase connection from supply and only one phase with an inverter? If this is the case then it is a stand alone. No need to tell it it is three phase
