EG4 18kPV To MQTT ( Home Assistant ) - OpenSource - Python Server / Script - [PythonProtocolGateway]

[hotnoob]

EG4 inverters have been confirmed to be working with my project... which i swear i rebranded / renamed for the last time

This allows you to plug your inverter into a server / computer / device with usb ( in the case of eg4 a modbus to usb cable ), and have it dish out it's information to Home Assistant via MQTT.

with the help of the community i'm confident that basically any inverter / solar device can be added to this project.
but with it being the summer time i'm a bit too busy with adding new features, so could be a while
on the todo is weird dynamic protocols such as pylon rs485 ( half working ) and canbus

Python Protocol Gateway is a python-based service that reads data via Modbus RTU or other protocols and translates the data for MQTT. Configuration is handled via a small config files. In the long run, Python Protocol Gateway will become a general purpose protocol gateway to translate between more than just modbus and mqtt.

For specific device installation instructions please checkout the wiki: Growatt, EG4, Sigineer, SOK, PACE-BMS https://github.com/HotNoob/PythonProtocolGateway/wiki

Intro to the project

Nice! Definitely will be doing this! What RS485 port did you use on the 18Kpv?

i'm suspecting inv485, i'll get the wiki written for detailed device specific instructions in a bit.
have to collect some firewood first

It looks like INV485 is in parallel with the network dongle, but Meter485 might be available if you don’t have a Smart Meter to talk to.

yup, manual says all 3 can be used. in the above case, the INV485 port was being used.

Yay! Now to figure out where to mount the batteries/conduit boxes, and inverters so I can get started!

Thanks for doing this!
