SofarSolar HYD inverter modbus AntiReflux Control

Can anyone help me?
I’m integrated and can read all data from inverter I need.
Now I would like to change AntiReflux_Control value but I’m unable to.

I see value that is inserted on inverter and if I change it on inverter, then I see changed value correctly.

number:
  - platform: modbus_controller
    modbus_controller_id: inverter
    id: power_reflux
    name: "Reflux (0 - can sell, 1 - no sell, 2 - limit)"
    address: 0x1023
    register_type: holding
    value_type: U_WORD
    min_value: 0
    max_value: 2

Now when I change it in mu home assistant then I see in logs

08:52:15	[D]	[number:054]	
'Reflux (0 - can sell, 1 - no sell, 2 - limit)' - Setting number value
08:52:15	[D]	[number:113]	
  New number value: 2.000000
08:52:15	[D]	[modbus.number:061]	
Updating register: connected Sensor=Reflux (0 - can sell, 1 - no sell, 2 - limit) start address=0x1023 register count=1 new value=2.00 (val=2.00)
08:52:15	[D]	[number:012]	
'Reflux (0 - can sell, 1 - no sell, 2 - limit)': Sending state 2.000000
08:52:17	[D]	[modbus_controller:032]	
Modbus command to device=1 register=0x1023 countdown=0 no response received - removed from send queue

And the value gets just changed back what it was before (as I understand, it does not reach to inverter at all).
What I’m doing wrong?

Hi Maarek!
Found the solution?

No I don’t have a solution.
With my hyd 8ktl-3ph it is not working,
with friends hyd 15ktl-3ph it works just fine.
I tried to update firmware, but no luck.

When I change reflux manually on my inverter, then I can see it change in homeassistant ESP also

Hi, are you able to see AntiReflux Power value in HA? Or could you set it like 0 - 6000 ?
