+# solax-x3
+####  Read in real-time all parameters provided by Solax X3 solar inverter via its Modbus S-485 serial interface.
+
+<br />
+
+## Prerequisites
+
+* Solax X3 inverter
+* Modbus RS-485 serial adapter/interface
+* [Modbus cable](https://github.com/mkfam7/solaxx3/blob/main/diagrams/rs485_cable.png)
+* python version >= 3.8
+* This python module
+
+## Installation
+
+```
+pip install solaxx3
+```  
+
+## Usage
+
+
+```
+from solaxx3.solaxx3 import SolaxX3
+
+# adjust the serial port and baud rate as necessary
+s = SolaxX3(port="/dev/ttyUSB0", baudrate=115200)
+
+if s.connect():
+    s.read_all_registers()
+
+    available_stats = s.list_register_names()
+    for stat in available_stats:
+        print(stat)
+
+    battery_temperature = s.read("temperature_battery")
+    print(f"\n\nBattery temperature: {s.read('temperature_battery')}")
+
+
+else:
+    print("Cannot connect to the Modbus Server/Slave")
+    exit()
