prometheus-solaxmodbus-exporter-php

Prometheus exporter for Solax inverter data over the modbus protocol

Requirements

Solax Pocket Wi-Fi 3.0

This seems to be the only dongle that supports modbus. I've also tested the Pocket LAN 3.0 and that definitely doesn't work.

Solax X3-Hybrid inverter

Other Solax inverters should work fine if you correctly define the registers in the registers.yml file.

Usage

Build the container

docker build . -t prometheus-solaxmodbus-exporter-php

Running the container

Make sure to properly set the 3 environment variables in docker-compose.yml

docker compose up -d

Check if it works
