Could you share your config? I’m trying to get my G3 to work and there is not much data about that to work with.
Hi,
Have you managed to create full config file for ESPhome? Would be really great if i could save some time porting it for G3 by myself 
Hello,
I would need help. In the case of “8.8 KTLX-3”, where should the TTL converter be connected?
I tried it on “Electric meter RS485A” and “Electric meter RS485B” but without success.
Where should it be plugged in? It doesn’t have an RJ45 shape for me.
I will add a picture from the manual.
Thanks for help
Thomas
Or 7 and 12 ports should I use?
7 to the negative and 12 to the positive?
Just so you know I have started to add in support for Sofar Solar on my SolaX custom_component SolaX Inverter by Modbus (No Pocket WiFi) ( now a custom_component ) if you fancy Beta testing give it ago and let me know. (It will probably fail on the serial number check (only checks first couple of digits to determine model) but that can be easily fixed once we know what it is)
Did you get connected?
I don’t own a Sofar but looking at that Diagram you want Pins 1&3 or 2&4 You might need to connect Ground as well Pin7 but on SolaX Inverters that’s normally not required.

Witajcie, czy macie pomysł jak zintegrować falownik Corab Encore FALOWNIK CORAB ENCOR HYBRID 8K+MODUŁ KOMUNIKACYJNY WIFI ?
Hi,
Is-it compatible with sofar 2200 TL G3 ongrid inverter ? Thx
@sargus123 Hi,
Sorry to bother you… I tried your code with my 2200 TL-G3… I have no data 
…
I triple checked all connexions… You are using the 2p RS485 port ? with TX-<=>B- and TX+<=>A+ ? No extra GND ? (I don’t know in this case how to wire it, no GND pin available). Do you power your RS485 converter with 3V3 or 5V ?
Best regards,
Udało Ci się wykonać integrację z Corabem?
