Eb3a shutting down due to lack of battery, even with capacity above 40%

Hello, I have a problem sometimes with my eb63a station, it turns off claiming low battery, but always above 40% 50% battery charge, I noticed that this always happens when I’m using 100% solar energy mode as a charging source. What I noticed is that for example the solar panel is generating 80w of power, and the ac consumption is 110w, in theory it should be taking this difference from the battery, and show in the battery status that it is discharging, but this does not happen, it shows that the battery is being charged including increasing the battery capacity on the display. I have already done the procedure to calibrate the SOC and I’m still having problems.
