Hi,
I've got an ESS with PV in front and on the back of an Victron Quattro 8 kVA.
I get the PV values from SMA SB 2.5 via ModbusTCP, so no real Sensor.
If i calculator the production and the AC usage, I do not come to the same number as advertised at Grid. I hope you can understand my Question.
CCGX, Quattro 48/8000, ET340 with RS485 to USB, BYD LV 7 kWh at 48VDC, 4x SMA SB 2.5, ESS.
As this is 3 phase and there are lots of connections and cals and there is no details
A full wiring diagram would be needed and setup description IN DETAIL
there are multi areas that the info comes from as well
so maybe you will have to work it out by disconnecting this and that and seeing the results
we can try and help and guide when needed
Probably a configuration error for one of the PV inverters / critical loads.
the error seems to be about 2-2,5 kW so that's a clue.
