I am asking the community if anyone is using the Orion bms 2 jr in their inverter setup. I know it works well with the can bus on the Quattro from what I have read. Trying to validate if it works well from someone with experience of this specific bms integration. Thx
Moved to "Modifications Space" for discussion regarding non-supported systems and components.
Did you ever get any clarity on this? I am trying to integrate a Phoenix inverter into my Orion Jr's CAN network and think I need some sort of gateway...
Chris,
no I did not and based on some info I got from another engineer I went with a less expensive BMS that is not can integrated.
good luck.

I'm successfully using Orion Jr 2 with my split-phase quattro setup & cerbo gx. The cerbo is required because that has the CAN bus on it (the quattro's don't).
How much data from the Orion BMS can you see on the Cerbo GX? Are you able to see individual voltage of each cell?
You can't see individual voltages (at least not out of the box). You see SoC, DCL, CCL, CVL, Health, temperature, and I think that's it. The advantage is that it controls the charge current across all the Victron equipment. The downside is there's no built-in way to go from Absorb to Float. There's only Bulk and Absorb. I think I'm going to need an external way to influence the separate "charge ready" signal which can have different voltage parameters so that I can treat bulk like float and have a manual absorb or something. That's OK for LiFePO4 ... not so great for many other types of cells/batteries.
You can also get lowest cell voltage and cell number and highest cell voltage and cell number.
The Absorb to Float isn't a problem for LifePO4 as you do a constant current/constant voltage charge anyways which the BMS can control with no problems.
