Since spring I use auto-modus with my Victron EVCS charger. However since then there is a grid draw between 250 en 550 Watt. Last year it didn’t do that.
My grid consumption is very low from spring till fall. And I am not aware of that I did any change in settings that causes this. I’ll attach a screenshot of the VRM.
In the shot EVCS charges with 9A while it can go down to 6A. But it doesn’t.
If the charging current goes up or down the grid draw stays the same.
These are the settings I can think of that have an influence and how they are:
Grid setpoint: -20W,
single phase,
tried DESS on or off doesn’t make a difference,
SoC 100% or less makes no difference, less then 100% keeps approximate 1000W for charching the battery (2x pylonthech u5000)
tried Grid setpoint to -500W no difference
Checked modbus against victron white paper settings, everything oke
Getting frustrated, did a lot of research online no solution.
Hope there is someone here that can help, what am I overlooking?
How is the grid measured? At least here, both the ACout load of 3927W and the PV production of 4015W do seem to correlate quite nicely, including some conversion losses.
What do the device details say of each device MP, gridmeter and EVCS in the remote console?
This is what happens in manual mode, Energy is drawn from the battery instead.
It’s better/cheaper, but beats the purpose of auto mode where it can go up further and automatically throttle down when ac-loads get higher.
EVCS rapport assumes 0kWh from grid, in reality it’s 1kWh. The total grid costs for my case, where my grid usage is minimal and fixed rates make high prices, it cost me 0,99€/kWh.
So this doesn’t make me so happy. Battery energy is cheaper.
