That would depend on how the system was setup, one could program the software for non critical fault and use an expansion board to trigger another shunt trip breaker if a breaker was on each battery or a parallel bank. There are multiple ways it can be done, the system is flexible and adaptable.The way this is worded can be misinterpreted. If you have a Batrium Core and 2 K9's for each of your 16s batteries it can not shut off an individual battery bank. Your entire system will turn off if one of the battery banks triggers a fault. With two JK-BMSs only the battery bank that has the issue would be turned off so you would still have power from the other bank to power your system.
It's always been an argument, some prefer complete shutdown until the fault is found, others want the ability to run in a limited capacity but this might cause failure of the battery still running due to the increased load on it .
What's the answer? If one is totally dependent on their solar system, it needs redundancy where it can still handle full load. It can be accomplished several ways, however if one had a large load on a 2 battery bank with FET based BMS's and one suddenly shuts down, the increased load on the remaining battery might cause catastrophic failure in the FET based BMS.
There isn't one answer for every system, much depends on the needs of the user.
