sungrow

A Prometheus exporter that scrapes a Sungrow inverter for information about solar generation, usage, and other fun data. It includes a (minor) fork of github.com/goburrow/modbus (to enable working with Sungrow's "encryption").

This is part of my own custom solar monitoring setup, so has a few quirks suited to me. In particular, it exports the necessary tariff values to compute import cost and export value - if you are using Aurorar Tariff 93 in Tasmania. It defaults to connecting to the IP address of the inverter on my home network.

⚠️ There is ABSOLUTELY NO WARRANTY provided with this code. If for whatever reason it blows up your inverter, THAT'S ON YOU.

Building

Docker is recommended:

$ docker build -t sungrow .
