Read value from Inverter of solar energy station via Modbus RTU RS485

We are developing a project: a solar energy monitoring system.

We need a program running on linux, it can read values from inverters via Modbus RTU RS485. And upload to [url removed, login to view](you don’t need to implement this uploading function)

Totally 3 kinda brand of inverters should be implemented. User can edit the configure file to choose which inverter this program gonna read.


1. Data sheet of Modbus protocol will be supplied

2. The flow chart of the program and The Schema of Parse will be supplied, but if you have better suggestion provided, we can pay extra.

3. The flow of this program should be,

1. check if configure file configured

2. if the profile of electricity station in the configure file exists on parse

3. scan all the inverters connected

4. check if the inverter profile

4. The program should be commented well
