The following problem occurs: DESS no longer follows its planning, when the planning indicates to only charge the battery, the current goes from the battery charger to the battery. However, the AC PV inverter puts all the current on the grid, which is not the intention. The target charging status in the Cerbo, under ESS->DESS is --%. The target charging status is then apparently not sent from the VRM to the Cerbo or vice versa. Also when DESS is switched off, the functionality of ESS does not work, including the functions “grid setpoint”, “turn off PV feed-in to grid”. The system now lives a life of its own and can no longer be influenced by manual settings. Before August 28, everything worked perfectly and without changes to the system this problem arises. The change came into the system around 10-11 am. How does this happen and how can I solve this. Do other people have problems with this?
In the screenshots you can see the difference between the planning this morning en what DESS actual did this day. Since 12 o’clock this morning the heating of the buffer tank has been turned on (6 kW) to be able to give a little bit of control to Victron.
