DVCC Maximum charge current problem

My system: 12V Victron smart lithium 200AH, MPPT 150/60, MP 12V/3000/120, CCGX, BMV702

This is on a mobile unit and therefore is NOT on ESS

I have used VE configure to increase the charger to 60A on the MP and when using the limit charge current under the DVCC settings on the CCGX, it doesn't seem to recognise the MP charger at all. For instance, I can set the limit current to 3A and although it will reduce the MPPT to about 40W and works fine in that regard, when I increase the setting to 80A I only get the max that the PV is producing and no input whatsoever from the charger on the MT. I assume that both the MPPT and MT should provide current to the battery in that scenario with priority for the MPPT. This is not happening.

I suspect the charger may have stopped working as it only seems to be working on ‘Passthrough’

Thirst thing I would check is neutral / live error on the AC input.

Make sure that in the MP that the remote control is turned on for the current limit. otherwise the change in the CCGX will not make any changes

its a smail tick box

this is done in the ve configure

On VE Configure, under the 'General Tab' the AC input is set to 16A and next to that is a 'Overruled by Remote' checkbox which is ticked and under that is a 'Dynamic Current Limiter' checkbox which isn't ticked. This is for generators anyway.

Under the 'Charger Tab' the 'Enable Charger' tick box is ticked.

Thanks very much for your answer but I don't think it can be the solution.

Problem solved, I contacted my dealer and it turned out to be a detail in an assistant that I had changed!

Problem not solved, although the MP charger is now working, it is dominating the PV charger and not controlled by the DVCC current input limit.

It might help if you post screenshots of all the setting pages in VE-Configure, and also of the assistants.

My dealer has now got Victron involved so I think once the problem is solved I will update here with the solution.
