BMS collects the voltage and temperature of the single cell of the battery module (supporting lithium iron phosphate and ternary lithium) to calculate SOC, SOH, the max. single cell voltage/temperature, the min.

The real cause is often a limit in the path from battery to inverter. It can be a strict low-voltage cutoff, a surge that exceeds the BMS limit, or a simple voltage drop in the cables. The inverter can click off when a compressor.
