The ``Havells Inverter`` sensor platform allows you to use Havells inverter data reading on modbus
(`website <https://www.havells.com/en/consumer/solar/solar-on-grid-inverter-and-solutions/solar-on-grid-inverter.html>`__)
with ESPHome.

    Havells On Grid Solar Inverter.

The communication with this integration is done over a :ref:`UART bus <uart>` using :ref:`Modbus <modbus>`.
You must therefore have a ``uart:`` 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.
