Epever status unknow value 19

Hello everyone, I have a template where I can view the values of the photovoltaic system. I have a “19” value for a few seconds in the Pv system which I don’t know what it corresponds to in the modbus . I am attaching the image and the taml file of the section.

              '2' : 'UNDER VOLTAGE',
              '3' : 'NONE',

          {% set state =  states.sensor.PV_Battery_Status_1.state %}
          {{ mapper[state] if state in mapper else 'Unknown' }}
