DVCC takes FULL Control?

Morning @all

My installation consists of 2 batteries, 12 and 48v, with two separate shunts. 48v (lifepo4) battery is charged by 2 MPPT’s (and a Multiplusll), 12v (AGM) battery by one MPPT.

All are hardwired to CerboGX as well as the REC bms, which controls the 48v battery.

BUT, using DVCC, the REC bms takes over the control of ALL chargers (which works perfectly for the 48v battery) including the charger for the 12v battery.

This charger shows „remote controlled“ and stops charging .

How can I exclude this mppt from being controlled by the bms (without disconnecting from VE direct, it has no BT) ?
As far as I digged into this issue, it seems not possible right now?

What you are trying to do is unsupported in that scenario.
You need to separate them, either standalone or with a dedicated GX for the mppt, or maybe a DC to DC converter and shunt (as DC load) from the 48V system is a better option.
