Running ESS and systems starts discharing 4kW, why?

I found another discussion ongoing which is probably exactly the same as I’m experiencing:

Ignores discharge power to float voltage

I’m using a JK BMS which uses float voltage and three Multiplusses 8000VA. When the charge voltage of 55.2V is reached for an hour it will go to float voltage of 53.6V. When it does that, the inverters will discharge at maximum power and it ignores the maximum discharge power set in remote console under ESS. I’ve set the maximum discharge power to 14.6 kW, but when this happens it will discharge with 21 kW and gives a high discharge alarm. Why does the systems ignores the set maximum discharge …
