@Tarek YagOk I will try this configuration in the next few days. But I'm not convinced. I only have a battery pack made up of 2 batteries, a master and a slave. With your setup it's as if there were 2 groups with a master drum each. The current configuration is attached. The L0 cable goes into the BMS port of the inverter.

Good afternoon everyone, I have a Model AVM4T4K5K-24 inverter, connected to 2 PYLONTECH UP2500 batteries, the "A70" error often appears despite the batteries being at 75%. The firmware version is:
U16003
U23905
U30000.
The parameters 
12 is at 10%
13 is at 20%
29 is set to 10%
The inverter is not connected to the public electricity grid.
I had the manufacturer send me a new firmware, 60.87 and MC 39.17
Do you know if there is a newer version?
Furthermore, by changing parameter 5 from PYl to USE and setting the right voltages, the inverter works correctly. The batteries are all connected correctly with the original cables. The Dip Switches are 1 ON 2-3-4 OFF on both batteries.
Do you know if there is a newer version?
I attach received firmware.
