Victron Cerbus GX stops charging intermittently

Hi,
I’m controlling a Victron Cerbus GX system via Modbus. To charge the battery I issue a modbus command as per below. I notice some strange behaviour that it will happily charge for a period (10-20 mins) and then stop charging. If I send the modbus command again it does not start charging either. If the Cerbus GX is rebooted it will start working again. Why would this happen?

address: 2700
unit: 100
value: "10000"
hub: victron

Maybe some more info are in order?..
Meaning, type of system, feed-in or not, ac loads at the moment of stopping, SOC at the moment of stopping, etc.
