(Use, monitor and control any battery brand with any inverter)
This application is reading data from a BMS and sending it to an inverter. This way you have no restriction on what battery brands you can use with your inverter. Many inverter manufacturers only allow batteries from certain battery manufacturers and certain models. This project enables you to read your BMS's data via different protocols - RS485, RS232, UART, ModBus or CAN - and write the battery data to the inverter in a specification that the inverter supports - Pylontech, SMA, Growatt, Deye, SolArk, etc. You can monitor each of your battery packs cells and view alarm states on the included webserver or hook up via the MQTT broker on your smart home. Or you can just read out your BMS's data and use the optional MQTT broker or Webserver to monitor your batteries packs and cells wherever you are.
The (reference) project uses a Raspberry Pi 4B with a Waveshare RS485/CAN hat or Waveshare 2-Channel CAN FD HAT module but you can use any CAN or RS485 module for your PI that provides ports like can0 or /dev/ttyS0 or similar. It will also work on older/newer PI's such as 3 or 5.
The appplication supports multiple BMS (even mixes from different manufacturers), aggregating them and sending the data to the configurable inverter.
This way you control what gets send to the inverter.
A wide range of BMS and inverters already supported (see below). Any BMS or inverter can be supported in a very short time by just mapping the manufacturers protocol specification in an own implementation of the BMS or Inverter.
NOTE: If you would like me to add a BMS or inverter module just let me know! I would appreciate support to test the BMS and inverter bindings in all variations. Please let me know if you would like to support this project - Testers are very welcome! :)
