I have two battery banks (EG4 and Eco-Worthy) and a Smartshunt. I use the Smartshunt to aggregate all the battery data into one BMS. I would like to just be able to view the other two as well in VRM to see how they are tracking. I can connect both batteries to the two Cerbo MK2 CAN BUS ports, and they show up just fine, but NOT when they are both plugged in at the same time. Can I trick the system by using USB adapters or some other input to see the SOC on both batteries at the same time?
Yes, once they have been detected. The problem is that it won’t detect two CAB BUS BMSs at the same time.
If you have the latest Cerbo GX, then there are 2 different CAN bus ports that can be used for the BMS, connect one to each.
you can’t operate 2 different BMS units on the same CAN bus, as the ID’s used for the data would conflict.
That’s what I did. As long as only one was plugged in, they each showed up, but if both were plugged in they
wouldn’t. Doesn’t the unit automatically assign two different IDs to the two different ports?
Don’t think so. Never tried this. Alternative is to use an external device to aggregate the data, and to work out the lower of the two CVL/CCL limits.
I have tons of ways to monitor these… just thought it would be nice to do it all in VRM.
