ESS not discharging the battery

DIY

Hi,
It’s my first installation. A multiplus-48-5000, with Enphase MOs AC-coupled and monitored with an ET112, plus another ET112 on the grid IN. Battery is 3*dyness B4850 : 150Ah.
All seems well being, flows are recognised in the good directions in venus.

But since I added the ESS Assistant, all settings done on self-consumption are not working. I see ESS in venus, but the batteries are not used to feed the house.

All loads on AC-OUT
Batterylife ON
Min SOC 25%
Target 0W
DVCC ON with all options OFF (split charging well with it)

I’ve checked all possibilities of the FAQ, except LOM suppression.

I’m stuck to find what is wrong.
Example of low utilisation of the SOC :

I found out my error.
I was playing with the MPII modbus register for automation weeks before the real installation. I made mistakes on register 2701 and 2702 set at 1 instead of 100. Don’t know why
