EV Charging Station on AC IN - charging only from grid not from solar or batteries

Dear community,

I have EV Charging Station on AC IN. Consumtion is metered via inverters (no ET or CT).

All loads except the EV Charger are on AC OUT.


Explanation of problematic behaviour:

- when charging, only grid power is used - the system does not start to discharge batteries or ramp up solar

- the consumption of the EV is not summed up with grid consumption.


My initial idea was that Cerbo / EV Charger comms. are broken, but it is not the case. Also I did upgrade all FWs to latest versions.


Thank you very much for support.

Any chance you are using some mqtt-2-evcharger implementation there?


Some of them are not well programmed, and only report the AC-total to dbus. Then it will show the total values, but nothing on grid, because L1,L2 and L3 powers are left at 0.

Nope, :-( MQTT is disabled, and no instance such as Node-red nor any other automation platform is implemented on this site.


Only a Fronius is AC coupled, but we use native Victron integration.

That being said, no custom plugins or software that would interfere with dbus are implemented.
