File SOFARMap.xml contains MODBUS inverter's registers mapping for Sofar Solar K-TLX product line
and Prometheus metrics configuration.
Edit i.e. to get different language, other Prometheus/InfluxDB metrics names or
if Your inverter has different register's numbers.

Steps to run Prometheus+Grafana support:
    1. Configure prometheus options in config.cfg
    2. Serve prometheus metrics file using any web server (name it index.html to be the default page in configured path)
    3. Configure prometheus target to access the file 
    4. Add Prometheus datasource in Grafana
    5. Import grafana_en/pl.json file (Dashboards->Manage->Import).
    Enjoy :)

Steps to run InfluxDB+Grafana support:
    1. Configure InfluxDB options in config.cfg
    2. Create database to store inverter data in InfluxDB (i.e. create database Data)
    3. Add InfluxDB datasource in Grafana (name it InfluxDB)
    4. Import grafana_iflux_en/pl.json file (Dashboards->Manage->Import).
    Enjoy :)
