.. warning::

    Enabling all modbus registers will probably cause a stack overflow in main


Tested with Tracer-AN Series 10A/20A/30A/40A and XTRA Series 10A/20A/30A/40A.
Probably works for other EPEver MPPT controllers as well.


Below is the ESPHome configuration file that will get you up and running. This assumes you have a ``secret.yaml`` with ssid, password, api_password and ota_password keys.
