Low battery notification while it does not appear low

[christophedm]

Hi,

I am getting alarm low battery voltage, which then stops the operation.

When I check the battery it’s voltage does not appear to be low or discharged to a level that is alarming.

The alarms comming from the BMS are all OK

I also checked VE.Configure for the voltage values which are in alignment with the battery manufacturer.

Manufacturers manual for reference.

Update:

Appears to happen at 51.75v

What is causing the alarms? Is it an actual short voltage sag? Or more a configuration I am missing?

Thanks!

Just as a sidenode, the official documentation about using Pylontech batteries states to set these values to 46V.

Dynamic cut-off values: set all values to 46V.
