What is there were a device at the alternator output that monitored the output voltage and switched off the alt if the voltage went outside adjustable voltage brackets? It could also trigger a light or alarm to signal a problem. Seems like a very simple device with minimal complications.
The main threat to the LFP batts overcharging (and BMS action for that fault) seems to be the alternator. I think it is pretty rare for a modern charger to go wonky enough to produce damaging charge voltage. We have surge suppressor devices to save the alternator in a BMS disconnect, but maybe a device to eliminate the risk of over-voltage from the alternator/regulator would get around the risk and concern of BMS disconnect from that cause.
It might be belt and suspenders similar to an exhaust temp sensor to warn you if you lose an impeller.
The other causes for BMS disconnect are less likely to take out the whole bank, so maybe alternator voltage risk management deserves a closer look. I agree the risk of all this is low, but I still run Sterling APDs on both alternators.
Sorry to veer so far off the Epoch track.
