A side project to collect, transport and store data from a Goodwe solar inverter.
Based on Marcel Blijleven's Python library, ported to Go and re-packaged as a client/server application.
This project is mostly for personal use - it hasn't been polished for wider usage and isn't yet compatible with the full range of inverters supported by the above library (it has been tested against a GW5000-EH).
The main git repo is: https://git.netflux.io/rob/solar-toolkit
It is also mirrored on GitHub: https://github.com/rfwatson/solar-toolkit
A binary which can be triggered using using a cronjob. It queries the inverter for metrics, parses and encodes them and sends the result over HTTPS to the server process.
A binary which accepts incoming HTTP requests containing inverter metrics, and writes them to a PostgreSQL database.
Once collected, the metrics can be visualised using any graphing software, e.g. Grafana.
- (client) improve error handling, e.g. during network outage
- (client) support more Goodwe models
- (client) allow fine-tuning of the collected metrics (e.g. ignore selected metrics)
- (database) migrate from fixed schema to a single JSONB column

To build the client for linux-arm64 (e.g. Raspberry Pi):
GOOS=linux GOARCH=arm go build -o solar-toolkit-daemon ./cmd/daemon
