Need recommendation for AC coupled inverter for 48V batteries (Australia)

[mynamebestname]

Bit weird to ask but has anyone seen these in full set up working state

I have 3 in parallel connected to a Victron Multiplus II 48 3000. I am working on getting the BMS to talk to the inverter but in the meantime, I am running without comms and it is doing fine. I have the batteries talking to each other, but not to the inverter (or the outside world at all) yet.

When running the three batteries without master comms , are all batteries maintaining equilibrium , ie no drift in total voltage ?

you have network cables just bridging between the three units right ?

I have two batteries, both showing BMS errors (LED blinking)). I suspect the BMS units are either faulty or in protection mode as swapping them causes the LED blinking to shift. If the fault were genuine, the blinking pattern would remain the same for each battery.
Also wondering if is any possibility to connect the pc with BMS board in order to read real time status and errors, maybe create a log file etc...

Any suggestion?

I had my battery modules get out of sync and then had an over current which has put the Samsung BMS into permanent fault and has fused the protection. I am replacing with JK-BMS as the Samsung BMS cannot be fixed.
