This is a simple program designed to query the basic runtime parameters of Voltronic, Axpert, Mppsolar PIP, Voltacon, Effekta, and other branded OEM solar inverters.

Please see this blog post for the original findings, and inspiration for this project.

@ned-kelly has also created a docker based Home Assistant automation of this project and tested it with both Serial & USB. It can be used as a fully-fledged integration to the inverter, with a user-interface and hooked up to a monitoring system such as Grafana - If you are interested, please head to: https://github.com/ned-kelly/docker-voltronic-homeassistant
build/compilation procedure:
git clone git://github.com/manio/skymax-demo.git
cd skymax-demo
cmake .. && make
The code requires your inverter to be connected either via USB or RS323, and can be configured in the inverter.conf file...
You can then run the inverter binary afterwards - By default, it will query the inverter every few seconds and return a JSON response to the console...
USAGE: ./inverter_poller <args> [-r <command>], [-h | --help], [-1 | --run-once]
SUPPORTED ARGUMENTS:
-r <raw-command> TX 'raw' command to the inverter
-h | --help This Help Message
-1 | --run-once Runs one iteration on the inverter, and then exits
-d Additional debugging
Note:
- When using the
txcommand, your commands will need to follow the specification outlined here. - TX commands will be executed directly on the inverter, then the process wil exit thereafter.
