Thats one of the threads that helped me 
EDIT: Just for completeness; i just learnt from another thread here that our RoarPower battery isn’t strictly compliant with the Victron BMS-can spec, specifically this comment from @guystewart ;
MPPT Charger stops generating, excess DC PV not being feed-in - #3 by guystewart
Our battery reduces CCL to zero when full, despite having a specific Victron setting in the BMS software.
