First time serial

Open Kirstabro opened this issue 3 years ago • 2 comments

I have just started using this project together with my SE3680H. Im trying to connect to it using RS485. Currently i have the Rs485-1 connected to a raspberry pi via a rs485-usb adapter. I have been struggling tryin to get the project working.

As of now I am running the command: sudo python3 semonitor.py -m -s 73****** -t 4 -vvvv /dev/ttyUSB0 However I keep getting a master ack timeout.

I am kinda lost, does anyone have any tips on getting this project to work?

Thank you in advance !

The parameters look like they are correct. The inverter needs to be configured to communicate over RS485 as a slave using the SE protocol. It's also possible that the data lines in the cable are reversed. Try swapping them at one end.

Thank you for your response ! I have switched the data lines and it still doesn't work. My solar edge settings are : rs485-2-conf > device type > solaredge Protocol > slave Device id > 1

I currently have a wattnode on the rs485-1 port. Do you have any suggestions as to what could not be working ?
