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’
