Decode SOFAR HYD 15KTL-3PH #2

Greetings. Thanks for the info, you did a great job. I tried to connect your block "node-red-sofar-ktl-x" to Wifi logger Firmware version LSW3_14_270A_1.08 inverter SOFAR HYD 15KTL-3PH, but my data does not match. The inverter sends me two packets:

  1. Length 14, every 2 minutes Inverter : msg.payload : buffer[14] [ 165, 1, 0, 16, 71, 31, 32, 6, 244, 70 … ]

  2. Length 834, every 5 minutes

inverter : msg.payload : buffer[834] [ 165, 53, 3, 16, 66, 32, 33, 6, 244, 70 … ]

I have a modbus table for this inverter, but I don’t know how to find the correspondence between addresses and actual data. Can you send the address table from where you filled in the "decode msg" function?

I did not use any table, i logged data to file, than with hex editor compared with https://home.solarman.cn/ data to find what is what. I took me some time but here are my results.

If u can get data from your WiFi logger with this python script, i will have node-red implementation in the near future.

You can try my node-red-sofar-ktl-x-request subflow. Change registers in subflow proprieties and than edit decode response node inside subflow according to your modbus table. I hope it will work for you.
