at 99% it's a wiring problem.... Be aware if you are using a DB9 male or female, the 1-4-5 can be reverted. In pratice with your RS232, you have 4 four combinaisons to test.

You are welcome! If you want to do me a favor please provide a photo of your rs232 converter + wiring. It looks like a proper connection/wiring is the hardest part of the journey. ;-)

I would like to add something very important.
It looks like after working OK for some time, occasionally my inverter stops sending data. I need to reset the unit to work again. In my case, I have to unplug both solar and grid power.
This is especially relevant if you're trying to make the adapter and you're not getting data, it could also be that the inverter doesn't actually send it so after each try power it off and on again.

Could you enable the debug output of the uart component and provide some more logs? It looks like the response to QPIGS is just QPIGS.

But please not my baud_rate is 2400. Changing the baud rate to 9600 doesn't see to change anything. It looks like it's working exactly the same.

Sorry for the confusion. I didn't want to suggest another baudrate. The important part was:

This isn't real traffic / this aren't real responses from your device. It looks more like an echo / wrong wiring:

I just received a new adapter and I tried with this one instead. The messages changed but they still don't look good to me.

Does this tell you anything? I will also try to make some photos and send them.

Did you connect GND properly? Please make sure the baudrate is 2400 baud.

Dude, you are the best!
This new adapter had a different pinout even though the board is quite similar. I incorrectly assumed the pinout would be the same but GND was switched with TX on this board as opposed with the other board. It's impressive that the chip was powered though.
Thanks a lot!
In conclusion for others reading this thread in the future:
- syssi is the best
- not all adapters actually work. I have one with MAX232 which works.
- try to rotate RX/TX until you get it right.

To be very precise: You are using a MAX3232. This is the 3.3V version of the MAX232. This is important & good because driving a MAX232 with 3.3V is out of spec and driving a MAX232 with 5V leads to a logic level (TTL) of 5V too. The GPIOs of a ESP aren't 5V tolerant.
