Hello Everyone,
I have a LOT of Victron blue boxes already installed on my motorhome. CCGX, Mppt 100/50, Multiplus 3000 (12v) BMV-712.(I like them a lot).
Now I am interested in installing some Lithium batteries, thus I need a BMS. The battery will be a 12v 600Ah (or so - maybe more) battery - probably in a 3 or 4P 4S configuration. I would like the BMS to interface with the CCGX - with the CAN-BUS.
I have been looking at the REC-BMS. It seems to check all the boxes - I would like to hear from people that actually use it. How does it work for you? Any problems?
I have a few questions:
CAN Connection - From what I have read, it seems all I need to do is plug the BMS Can wire into a network cable that runs to my CCGX. Make a couple of easy software communication adjustments on the CCGX and it will work. Have I missed anything?
Charging the batteries: From my reading it looks like the BMS will be controlling the charging by sending signals to the CCGX, as it gets full, the BMS tells the CCGX to reduce the amps, and the CCGX passes that along to the MPPT's, then when totally full, the BMS says - no more power, and the MPPT's don't send any more power. Is that what actually occurs? Also, will the MPPT's produce power for the loads, so I don't keep cycling the battery between 99 and 100%?
Connecting the BMS to Connectors (Kilovolt EV200) I am a little confused about the connectors to the Kilovolt EV200. Is all I need to do is just the connect the two wires from the relay to the load EV200? Do I do the same for the charge bus? How do the digital relays work? This is probably the area that confuses me most.
Thanks for your help
