1) I am integrating a LFP ABMS based battery with Cerbo GX and WS500 already in the system. I would like to confirm that the REC Victron CANBus cable is internally terminated and it is suffcient to remove the termination on the GX previously necessary for the WS500 and that is all there is to it for physical configuration.
2) I need to configure the system Victron Multiplus and GX such that it plays nicely with the LFP and the auxiliary/emergency FLA bank. Both batteries connects and disconnect the the main P-bus via ML-RBS as does the LFP battery. FLA is behind an Orion XS DC-DC and other details omitted for brevity. I need to figure out the procedure to switch from LFP to FLA.
The manual indicates:
Update GX device to 2.90 or higher.
Connect BMS and GX device with CAN cable. Use BMS-Can port with Cerbo GX or VE-Can port with
other GX devices.
Open Settings menu and select Services. Set CAN-bus profile to CAN-bus BMS (500kbit/s) for Cerbo
GX. Then in Settings menu select System setup. Change:
- Battery monitor to REC BMS in CAN-bus.
In menu DVCC:
- DVCC→ON
- SVS→ON
- STS → ON
This is OK for LFP operation.
I would like to hear feedback on the procedure to switch to FLA operation. This is what i have in mind
1) Switch LFP OFF and FLA ON (via ML-RBS).
2) Manually Disable DVCC on the GX device.
3) Perform a VE.Bus Reset on the GX device.
The MultiPlus-II's inverter is now active and powered by the FLA battery and the FLA is charged via DC-DC.
I understand that this process could be controlled via node red, but that is to the future once all is up and running.
I appreciate any comments or corrections.
Thank you,
Stefano
