I've forked a project I found on github and made some mods to it so that it polls a voltronic inverter and spits out the values received to standard out in JSON format. The program is written in C++, requires no external dependencies and is very light weight. In fact I helped develop it to compile and run on my Raspberry Pi 1 B+. The point of it is to use some other program to run it and handle it's output. For instance I use telegraf's exec plugin to run the program once every 15 seconds and take it's output and send to an InfluxDB instance where I can later graph it with something else (grafana).
Also the program can be used to send raw commands to the inverter (some examples given in the programs help). Anyway I have been using it for half a month now and I figured I'd share it if anyone else wants to try it out.
