I'm still receiving a overload warnings. Don't know what's a reason for this and if it's necessary to change any settings. Is this warning comming from the Multiplus ?
My configuration is :
Multiplus II 48V/5000
3x Pylontech US3000C
MPPT 450/100 + MPPT 250/60
Maybe problem is this setting :
Don't know if it's correct
Thanks for help

You are running the 4kW inverter flat out. The warning (it is only a warning) coincides with high usage, it is probably just a brief hiccup as loads shift.
The harder it is run, the hotter it becomes, the more it will derate.
If your firmware is up to date, it is just usage related.
You can see these warnings even on larger systems as it can also be grid related.
It is unlikely to be an input current limit, 40A equates to 9200W at 230V.
If everything is working fine I wouldn't worry about it, and just disable notifications for warnings, set it to alarm only.
Thank you, question is, why there is a overload warning, because on the AC OUT is "only" 2,4kW and the rest 1,9kW is supplied via AC IN and I think it isn't necessary for inverter to supply. So for me normaly overload warning is valid only for AC OUT.
You also appear to have a meter installed and AC loads parallel to the inverter which the inverter will try supply via backfeeding.
The diagram only shows the AC loads and Critical loads, not the grid supply.
But the total consumption indicates the inverter is suppling both at its full rated power.
So while critical loads may only be 2400W, it is also supplying near 1900W to the AC loads behind your meter on the grid side.
