Deye - low power mode

Hello!
Anyone using "low power mode"?
It doesn't work for me.
I have a parallel system of two SUN-6K-SG03LP1-EU inverters.
Low Bat set as 51.2 Volt.
Time Of Use Voltage set as 51.1 Volt.
Checker for "Low Power Mode<Low Batt" set is on.
Grid is connected.
PV is disconnected.
The battery voltage reaches 51.1 volts. But the inverters do not switch to the low power mode.
Anyone have any ideas?
 
FYI

I contacted Deye about this a few months ago and this is the response from tech support.
The manual is really bad in my opinion.

TOU = Time Of Use

Low power mode:

Function description: When the current SOC is less than low batt and the photovoltaic voltage is less than 50V, the inverter will stop output after enabling this parameter for 20 minutes, and the red light and fault report will not be displayed. The power on the grid side is maintained at about 14 watts. If there is a load, the machine stops output, the power grid continues to run with the load, and the load cannot be stopped (the page normally displays power); When the photovoltaic voltage of any road is greater than 50V, the inverter starts, the normal light is on, the photovoltaic battery is charged until full in CT mode, and the remaining energy is connected to the grid after the power sale mode reaches the target value. (When the photovoltaic voltage is 50V~150V, the photovoltaic energy cannot be fully output, and when the photovoltaic power is greater than 150V, the photovoltaic power can be normally output). The TOU value can be set to less than low batt1%, and the battery can discharge to the TOU value, not the Low Batt value

Thanks!
But I'm using volts instead of percentages.
I also contacted tech support four days ago.
But I haven't received an answer yet.
