modbus-solar 1.0.0

A small package to pull stats from a Renogy Solar Charge Controller

Modbus Solar

Intro

This project is to pull stats out of a Renogy DCC50S solar charge controller.

The connection will be made via Modbus/RS485.

The end state will be to output stats in json format ready to be ingested into something like an InfluxDb instance or to publish to a MQTT Topic.

Pre-Reqs

You require a Modbus/RS485 connector, most probably will be a USB varient. Most applications will be using a small IoT device or Raspberry Pi to serve the USB device and then connect back to a logging system of some sort.

The Modbus parameters are hard coded but variabalised for the device ID and the salve address which could change.

Using

pip install modbus-solar

1. Python

   from modbus_solar import get_all
   
   stats = get_all()
