Victron system integration

Hi,

Sorry i have posted this on Victron forum and if something comes up there i’ll sync here.

I have following :

• Multiplus II
• Cerbo GX
• Fronius AC Coupled inverter (connected to Cerbo with modbus)
• Carlo Gavazzi EM24 meter (connected to Cerbo with modbus)
• Victron MPPT

My system is 3 phase, the Fronius is producing on L3 and Multiplus II on L1
I want to have the battery, grid and solat into Home Assistant Energy dashboard and i got most of it in but it seems wrong, HASS shows more usage compared to VRM dashboard so i think it’s wrong.

For now i am using :

Grid L1 - Energy from net 2603
Grid L2 - Energy from net 2604
Grid L3 - Energy from net 2605
Grid L1 - Energy to net 2606
Grid L2 - Energy to net 2607
Grid L3 - Energy to net 2608

to get the consumpton from grid and return to grid.

To get the Victron MPPT in i use :
PV - DC-coupled power 850
to get the Fronius production in i use :
PV - AC-coupled on input L3 813

For battery i use :
Battery Power (System) 842
and then i make two sensors to have both + and - energy going to/from battery

My problem is that when i compare VRM portal to HASS i see following :

• Grid consumption in VRM is lower than HASS shows
• Solar production is higher in VRM than on HASS
• Total consumption from GRID is higher on HASS compared to VRM
• Energy to battery is higher in VRM than on HASS

Any ideas whats causing this ?

I should mention that my electricity provider has a meter where it calculates on all phases therefore i always go for hitting 0 meaning don’t feed back if i can use it. The consumtion in the house is on 3 phases and Victron system using ESS makes sure that when i use 1000w on one phase the system produces 1000w on the phase the inverter is on so the sum is 0w and i don’t pay to use 1000w when i also return 1000w but on another phase. I don’t know if any of this makes problem for the energy dashboard.
