How do i control Inverter via VE.Can connected BMS?


I'm using the Victron CCGX, v 2.23 to interface a BMS(Custom made one using CANBUS) and the Victron Energy Multiplus 48V 5000VA 70 Amp inverter/charge. I send the CCGX the charge/discharge and voltage limits, as well as the other battery parameters. I expected that when the charge current i send to the victron CCGX exceeds the limit i set, the inverter/charger should switch off but this is not the case, nothing happens.

I tried turning on DVCC as directed by the manual, turning the victron CCGX to an active controller, but it still didnt work. I then noticed that there is a parameter called "BMS control", which is off and i tried turning it on but it doesn't want to turn on.

Please what am i doing wrong, how should i configure the victron CCGX to allow the BMS sent values to take control of the inverter/charger.

Hi @Engineering_Centre

Please start by updating the GX firmware, then next steps. (is BMS seen? parameters visible?)

Hey Daniel

The BMS is seen as i am able to send paramters such as charge/Discharge current limits and low/high battery voltage limits as well as the SOC, SOH, Current, Voltage, Temperature values.

I will update the Victron and repost if there were differences.

Hello @Daniël Boekel (Victron Energy Staff)

I have updated the firmware to version 2.6.

The BMS is seen along with the parameters. I have attached a picture of the Victron displaying the parameters sent via the CANBUS.
