Where can i find the Low Battery voltage setting?

I've got a system with 400ah of 48v LiFePo4 batteries and I'm constantly getting low battery Voltage warnings. But they seem to be set at 52.08 volts which seems a bit high.

I have an ESS running in Battery life mode. Images of setting below:

I can't for the life of me find the setting that is causing this alarm. Can anyone point me in the right direction?

Can I also get a sanity check on my settings? Including recommended settings for the DC Input Low Voltage Shutdown?

Your dynamic cut-off values are to high.
I would recommend to set all to 48V or 47V.

You also have to check the Inverter Tab.

Thank you, that was it!!! I had more reasonable values set in the Inverter tab but apparently it is overwritten when an ESS is running with the dynamic cut-off values.
