Did you update the inverters mk3 version via the GX inverter tab?

No, I just updated the Cerbo through the VRM, all the other items were fully updated.

Yes I’ve rebooted the Cerbo, but will try again today. Prior to this last update all was working fine!

It is hidden away in the GX settings under the inverter tab and is not shown on VRM.

@Big Ste

I find it easier to pull the power cable out and wait a few seconds before reconnecting.

It always required 2-way comms.

Again, on the GX, check the inverter section and see if it is asking for a mk3 version update.

No MK 3 update request on the inverter

I assume this was a VRM issue since without doing anything everything works fine (for me) this morning.

Either that or there is a bug in v3.12

If that were the case I suspect a manual update of the firmware would have been necessary as it wasn't possible to communicate via VRM. I think there was a bug in one of the VRM updates which got fixed "overnight".

I did a hard reset, pulled the power cable off the Cerbo and all working again on the VRM
