I have a trouble for mult RS solar to communicate with a battery BYD I try to connect still working but not charging
This is my setup but still not charging my anyone can help
Your first screenshot show a nearly full battery at 54.76 Volts, and yet current is still almost 92 Amps! I hope you have more then one battery!
Don’t charge the battery again until the battery is able to communicate with the Victron Cerbo or Gx device, unfortunately I have no knowledge about BYD batteries.
Battery is two
Because battery blinking orange not blinking green
These have quite strange values.
Read about them in the manual and set them accordingly.
I would try:
Restart = 48V
Charge detect = 48V
Absorption = 56V
Float = 54.4V
Are you using a GX in your system or trying to connect it directly to the RS?
Those will work too.
In the initial pictures, you set the float greater than the absorption and the charge detect greater than all, even absorption.
That is a VE.CAN port not a BMS.CAN port which the battery needs.
IIRC you need to add a Cerbo and connect the battery to a CAN port configured with the BMS.CAN profile for comms to work.
You are also missing a terminator.
Everything you need to know is in here:

The port is 250kb/s byd battery is 500. You need a GX.
