-Edit the script and put your API key, site id and inverter serial number
+Usage:
+```
+solaredge_modbus.py [-d] [-l LISTEN] [-p PORT] HOST [PORT]
+
+Prometheus exporter for SolarEdge inverters
+
+positional arguments:
+  HOST                  Inverter Network Address
+  PORT                  Inverter Modbus/TCP port (default: 1502)
+
+options:
+  -h, --help            show this help message and exit
+  -d, --debug           Enable debug info in HTTP answers (default: False)
+  -l LISTEN, --listen LISTEN
