Measurement of battery storage energy direction

[larryj]

Hello,

I have in my set up a vehicle to grid car charger (v2G) where energy flows in and out. I would like to identify on the V2G circuit energy flow direction i.e. when it swaps from charge to discharge. Technically it’s difficult to do but I currently do this outside of the app by summing up the demand and PV generation and the net of this determines the chargers energy direction. Any way of doing this automatically?

Picture of the output I can produced from the data received.
