Hi has anyone got a clue how to connect the batrium bms to the ccgx, I have cabled it up, put in the correct resistors, gone through all the settings multiple times and can not see the bms on the device list. I have spoken with batrium (and apart from putting a new cable in, which I will do today) they were not a lot of help.
I would appreciate any help you can offer as I am about at the end of my patience :)
Batrium is not a compatible battery system, so I've moved this question to Modifications.
Hi
Is this still a problem? I have used a Batrium WatchMon 4 and Venus connected via CANbus for the past year and recently setup another similar system. The sequence of startup was the only issue and this appeared to improve with the most recent WatchMon 4 Firmware 2.0.12 upgrade. Doing a Power cycle on the WatchMon 4, after connection has been made, was how I got them talking before this Firmware version and this was a frustrating solution but makes some sense for devices establishing communication with each other.

I have a number of Batrium BMS/CCGX or GX systems running, the integration is very good and works very well.
My initial suggestions are to ensure the interconnecting cable is correct, and that you have the expected continuity - also confirm you have the data rate correct, ensure you do have a battery monitor selected - then reboot the Venus device, and then (after Vidtron GX has been selected from within Batrium toolkit/integration) reboot the WM4.
I can confirm that the instructions detailed on the Batrium site are accurate and that a Victron system re-detect is not required.
Edit: you've mentioned "resistors" - plural. How many do you have on the bus ?
are u running the batruim shunt ? do u know weather it will show up as a bmv would on the vrm portal thanks
Any help will be immensely appreciated....

I presum you have followed all the details for setup from batrium. https://www.batrium.com/pages/how-to-control-victron-venusgx-with-watchmon
if it still does not work and as this is a not supported product you should contact Batriuym support
Another thing make sure you do a system re-detect after you set the battery up, it could be as simple as that for it to show
As I don't see the re detect in there instructions
its under the multiplus and then under advance pages in the Venus
Hi Paul B
I have not jet purchased the Batrium BMS, I am currently comparing it with REC BMS, another option I have.
I am a bit puzzled about the "how to guide". It doesn't really explain how this will work in the end, but maybe that has nothing to do with the BMS. As soon as the CCGX gets feed in data from the BMS over CANBus it does all the "right things" both in controlling the MPPT as well as the inverter
It also refers to ESS, to my knowledge ESS is for GRID connection only, and not ment to be used for an off-grid solution.
A Batrium BMS will provide comprehensive charge & discharge control, assuming you have compatable components in your system - if you view Batriums control logic you'll see exactly what variables it can use, which include SoC, battery voltage, cell voltage, charge & discharge target rates etc etc.
Question to the Batrium experts:
Does the CANbus communication give Venus/CCGX device "instructions" on when to reduce charging , with how much, and in the end shut off completely and also shut down the Multiplus should the SOC get to low?
