Hello all,

I have a question in my charge config I have a charge curve for go down withe the Amps near the max voltage. Can I also make this near the discharge limit? My problem is that the bms say max upload and if the inverter go to max upload Amps than jump the voltage to fast down and he stop. This situation I have it a long time before it's empty.

Best Regards Michael

Hello Stuart,

for better understanding i have a 70kwh battery withe 3x Deye 12kw hybrid. If i come down to 41v than he have to stop but the discharge current is to high and the voltage go to much down and the system say its to down and i load from the grid to the battery and this go over the night every hour. A Curve for emty the battery is a must to have. see movie below.
