Question about EM540 and feed-in with negative grid set point

Hello, I have three questions


1. Is it worth setting the EM540 baud rate to higher than the default (9,6kbps) or the cerbo supports only (9,6kbps) ?

2. Is it normal that the EM540 meter has bad data (consumption, export and import to the network) on the VRM portal?

1. And another question, when I have set the grid point to -350W(permanently) and still at the end of the day I have a grid import of about 150-300W. Is it normal?

Setup:

EM540 (via usb rs485 to cerbo gx), cerbo gx, 3x MP II 48/5000/70, pylontech US5000 battery, ESS mode without battery life, all latest firmware
