Board does not connect to inverter

[Crapoto94]

Hi all, and sorry for my bad english :)
My sofar2mqtt is not connecting to the inverter.
The serial monitor show : "Timeout waiting for RS485 response."
For compiling, i changed D6 in 12, D7 in 13 and D5 in 14.
I can see the RS485 logo on the inverter, but the LED display CRC-FAULT ERROR.
I tried to invert the wires, the logo is still there, but il's stll not working.
I changed the MAX485 board, same issue. There is a red light on the board.
Can anibody help me ?
