Undervoltage alarm - why?

Can someone explain to me why I keep getting an "undervoltage alarm"?

I had already turned the settings down.

DC input low-turn off: 40.8V

DC input restart: 41.8V

DC input low pre-alarm: 41.8V


In the ESS Assistant:

Sustain voltage: 45.0V

dynamic shutdown: all 4 values at 46V


I can not explain it.

Check your battery connections. They may be loose.

Alternative is the bms is somehow causing an issue there. Check cell balance.
