The non essentials are not being fed from the battery what so ever. During the day time when there is sun on the panels as per the screenshot it is allowing to push back to the grid for a few seconds at a time of 700W. The essentials and non essentials are split correctly in the DB.

Hi everyone I have a Deye 8kW Inverter with 7,2kW panels and 3x 5,1kW.h lithium batteries installed. The inverter is set up with zero export to CT with sell solar function off (should not export to grid) however I find that the inverter from time to time for a second or two, it does export power to the grid (usually 700W) however I can not see any units being pushed back into the grid it does show it on the Solarman smart app. Looking at the total grid feed in for the day it shows as 0,0kW.h for the day. My concern is that I have set up the inverter to use panels as 1st priority, battery as 2nd priority and grid as last resort. I don't buy any electricity from the grid thus the inverter pushing power back into the grid will give me a neg reading on my meter over a longer period of time if this continues. I have attached a screenshot of what is currently happening - it then immediately returns to work as it should after a few seconds. It might not be a big issue but I would like to understand why this is happening, if anyone has an idea please let me know. My thinking is that it is a software glitch but I am hoping for a better answer to give to the customer as to why it is happening. Thank you
