October 7, 2025Oct 7 I've currently set my Deye inverter to discharge the battery to 1% starting from 12.05am to 12.00pm. So when the sunrises in the morning the battery starts charging again, around 70% is reached by 11pm. I have set the system work mode to "zero export to load" and the "grid selling when battery is fully charged" is turned on. however, when the battery reached around 70% the charging rate slows down, and it sells a lot of power to the grid. When I turn off "grid selling when battery is fully charged", the battery charging rate increases again. Does anyone know why this is and what I can do to make the grid selling does not happen until the battery is 100%?p.s. the inverter is connected to a JK BMS
