This Python code is intended to read recorded data from a Fronius Symo inverter device, typically used in connection with photovoltaic panels. It reads information about power, voltage, current, and energy from the networked inverter (readout_*.py files) . Information is then stored in an SQLite3 database. The same database is used for evaluation of data using Matplotlib (plot_*.py files).
The code can be deployed to a Linux platform, with periodic execution for data collection and evaluation. This can be realized with e.g. cronjobs. The resulting graphics can be published on e.g. a webserver.
