isv: Linux utility for controlling Voltronic hybrid solar inverters

Update from 2022: isv is no longer supported, please use inverter-tools instead.

Long story short, I have this thing called InfiniSolar V 5kW:

and I wanted to set up some sort of monitoring so that I would be able to access this thing remotely. Turned out that there were/are some projects for that (in particular this one worth mentioning) for similar inverters but they were using other (older?) protocol P16 while mine was using P18.

Luckily I found some leaked documentation on P18, so I wrote my own tool with all functions inverter supports and called it isv (for InfiniSolar V).

Please enjoy:
