Can't get useful data from SE10000H via RS-485, Unknown Function

[cschuhen]

Hello,

I have an SE10000H, connecting via RS-485, running latest firmware.

Inverter is set to SolarEdge Follower with ID of 1.

Python version 3.9.2 running on a Raspberry PI 2+.

I seem to getting some packets back but none that are recognized. I am getting these functions: 0302, 039a, 4288, 428a.

I also see this message on occasion: RS485 master ack timeout

I have tried many variations of the command for example:

sudo ./semonitor.py -t 4 -o 20221223.json -m -s 74047697 -d stdout -vvvv /dev/ttyUSB0 -b 115200 2>&1 | tee dump4.data

Here is some example data:

Ok, so I went to go check my firmware version to add do my post here. And noticed another configuration option.

In Monitoring Communication, I needed to also select RS485-1 as the connection type.

How stable is the connection for you, i've changed the monitoring to RS485 and i readed few data and the led turned blue but after few min the blue led turn off and receiving only 4288, 428a data.
