Solis Data

Gather data from a Solis inverter and push to web server.

Requirements

• Any Raspberry Pi with USB working;
• Raspbian 10 or higher;
• USB to RS485 Converter;
• Python 2.7.16-1 or higher;
• Solis inverter with COM port.

Installation

sudo apt-get install python python-pip 
sudo python -m pip install pyserial

Then place solis.py anywhere you want, create a cron like: */5 * * * * python /root/solis.py Finally adjust the code in solis.py, upload the PHP part to any webserver and start pushing data!

Hardware

Note that the COM input of Solis is proprietary, so I used some hacking to connect it, see the photos below.
