The communication with this component is done over a :ref:`UART bus <uart>` using :ref:`Modbus <modbus>`.
You must therefore have a ``uart:`` and ``modbus:`` entry in your configuration with both the TX and RX pins set
to some pins on your board and the baud rate set to 9600.

Configuration variables:
------------------------
- **inverter_status** (*Optional*): Status code of the inverter (0: waiting, 1: normal, 3:fault)
- **protocol_version** (*Optional*): Version of the protocol used by your inverter.
Old inverters use RTU (default). Newer ones use RTU2 (e.g. MIC, MIN, MAX series)
- **phase_a** (*Optional*): The group of exposed sensors for Phase A/1.
- **current** (*Optional*): Use the current value of the sensor in amperes. All options from
:ref:`Sensor <config-sensor>`.
- **voltage** (*Optional*): Use the voltage value of the sensor in volts.
All options from :ref:`Sensor <config-sensor>`.
- **active_power** (*Optional*): Use the (active) power value of the sensor in watts. All options
from :ref:`Sensor <config-sensor>`.
- **phase_b** (*Optional*): The group of exposed sensors for Phase B/2 on applicable inverters.
- All options from **phase_a**
- **phase_c** (*Optional*): The group of exposed sensors for Phase C/3 on applicable inverters.
- All options from **phase_a**
