Multiplus II, AC OUT 2 - how to read relay state, how to recognize grid code LOM were triggered

Hi, we have one site where there are some issues with Grid frequency & voltage stability sometimes at night.

It seems to me that under frequency or low grid voltage causes gridcode LOM settings to be triggered and AC OUT 2 is being disconnected. Customers notice induction hob - beeping at night.

But from graphs of VRM, or via node-red I haven't found a way how to monitor state of AC OUT 2 relay via software (hardware relay is a possibility but installation is far...). Or how to monitor LOM detection (caused by gridcode settings...).

Do you have any advice?

Thanks :-)

Enable the grid loss monitoring in the GX, it will alarm for both grid loss and grid rejection.

The causes of which can be found in the NS log (under the grid tab) in the inverter using a mk3.

It can be extracted remotely via ssh to the GX but it is a bit more complicated
