MP-II, DESS, Cerbo GS // node red // disable charge from grid, only charge from AC-PV

Hi all,

if i use trade mode (works pretty good) it will charge the battery most of the time in the night to 100%.
this mean between 10:00- 15:00 the AC coupled PV’s deliver back to the grid becouse the battery is allready full. (i want to safe that energy)
i,m looking for an option to disable CHARGE BATT FROM GRID after 80 %, the first part i have in node red. so the last 20% can charge from the AC-PV
but can’t find a way to disable charge from grid only. if i complete disable charge it won’t charge from AC-PV…
