Cfos Charging Manager + VESTEL EVC04 (OCPP) – charging always throttled to 4,6KW max by load balancing

Hi all,

I have a Shelly 3EM measuring the total house input power on a 3 phase installation (3x40A) and a Vestel EVC04 charger limitted to 32A (i.e. 22kw mode) attached in OCPP mode which the Cfos Charging Manager in load balancing mode.  The Total household total max power is set to 26000W , max power available to all EVSEs (one single) is 22000W and charger max charging current to 32000mA, but the Cfos Charging manager limits the charger always as low as to 4,6Kw charging max  no matter what power is measured by the Shelly 3EM meter and how much power remains for use of the charger. Any ideas what can be wrong?

Thanks

Daniel

Finally I have a working setup. Tried MODBUS TCP connection of CFos CM to the EVC04 Wallbox. It works. Thanks. Needed to start MODBUS TCP server in the EVC04 configuration by enabling Local Last Management:MODBUS TCP. Then it started MODBUS TCP standard port 502/Device ID 255. Of course the Wallbox needs to be connected either by ethernet or through its own WIFI hotspot. RPI with CFos CM is connected to Wallbox's own wifi hotspot and to LAN by Ethernet. In this setup. The EVC04 is still attached to EON OCPP backend {almost useless} by built/in LTE/VPN and to CFos Charging Manager local load mgmt. Thanks a lot for suggestion.

Haven't tried MODBUS connection to the wallbox yet in order to avoid the necessity to open Wallbox and wire the serial lines up to the RPI running CFos CM (which is even currently not easily physically reachable). I am not sure if the EVC04 with this FW runs MODBUS TCP/IP and allows to be steered over it.  Will give it a try. A physical serial connection would be the last resort for me. I would say VESTEL EVC04 seems to be on first sight feature rich a good bang for the bucks, but poorly documented and supported.

Did you try to connect the unit via Modbus.

Yes it's an eon branded unit. The VESTEL technical support does not seem to be available anywhere. The ZSE Drive (eon group member) don't give a ... There is unfortunately no place to download the new FW from.

Is it an eon brand box? Current Vestel fw is V3.57.0.

Ask Vestel-Support for new FW.

Do you have installed the latest Firmware 1.14.6 ?
Could you please provide a diagnose log that records the issue?
