:description: Instructions for reading data from a SUN-1000G2 grid tie inverter using ESPHome

The ``sun_gtil2`` component allows you to get voltage, power and temperature readings from your ``SUN-1000G2``
|
|
or ``SUN-2000G2`` grid tie inverter. This is done by reading the UART data transmitted from the inverter's
|
|
controller board to the display board.
|
|
|
|
.. note::
|
|
|
|
You need to open your inverter to apply this modification. Use at your own risk! If you want to connect your
|
|
inverter via the (more limited) external RS232 interface you should use the
|
|
:doc:`Modbus </components/modbus_controller>` component instead.

Simplified connection diagram
|
|
|
|
As the data is read from the inverter using UART, you need to have an :ref:`UART bus <uart>` in your
|
|
configuration with the ``rx_pin`` connected to the TX pin of the inverter's controller board. Additionally, you
|
|
need to set the ``baud_rate`` to 9600.
|
|
|
|
|
|
|
|
The inverter will report new measurements approximately every 1.3 seconds.
