How can I detect a defective PV converter?

I have 7 PV panel converters, 1 of which appears to be defective.
I want to create an automation that can tell me which converter is defective and send me a notification so that I don’t have to manually check all converters periodically.
Hopefully there is someone who can help me with this?

This concerns these PV sensors:
sensor.inverter_408000040627_power_ch_1 (ch_2)
sensor.inverter_408000041521_power_ch_1 (ch_2)
sensor.inverter_408000043541_power_ch_1 (ch_2)
sensor.inverter_408000043710_power_ch_1 (ch_2)
sensor.inverter_408000043914_power_ch_1 (ch_2)
sensor.inverter_408000045919_power_ch_1 (ch_2)
sensor.inverter_408000045948_power_ch_1 (ch_2)

Thank you in advance.
