The Multiplus should switch of the charger when Charge Current Limit (CCL) is 0 and should switch of the inverter when Discharge Current Limit (DCL) is zero, to really ensure, that there is not forbidden charging or discharging.
Currently Mulitiplus is still charging and discharging inspite of zero limits so driving a battery into overvoltage or draining a battery which already signalled discharge limit zero.
There is an issue on githib and also code which seems to solve the problem, but it has not been integrated: https://github.com/victronenergy/venus/issues/736
Also the Multiplus II is not behaving like it is documented in https://www.victronenergy.com/live/ess:ess_mode_2_and_3#running_software_on_the_ccgx_and_using_dbus_paths
It is not possible to disable charging via Modbus register 38.
