Yes, I have converter connected to 5v, because this is a voltage provided by inverter. I don’t remember what’s the voltage according spec of module, but I remember that on RX and TX 3v3 signal level is supported and esp8266 operates on this level.
Hey @pawelka, congrats on the really great job! I’m using the ESPHome logger with D1 mini.
I now plan to use it to automate charging my EV from surplus energy.
One question: The enclosure in my inverter is metal, how did you insulate your module?
Also a suggestion: the logger sends huge amounts of data, for us using an SD card it is a little frightening. I guess you also wonder:
[TODO?] all registers or only useful one?
I suggest:
- Increase update from 10 to 60 seconds perhaps?
- For most of sensors (except power) you can add the following, this way people who need it will just enable it in HA:
disabled_by_default: true
BTW I think we’re from the same country. Thanks again for your contribution!
HI! Great add-on. I do get the following error:
2022-05-21 13:30:44 ERROR (MainThread) [homeassistant.components.hassio] Failed to to call /addons/3a87ddeb_sofarsolar_mqtt/stats - Container addon_3a87ddeb_sofarsolar_mqtt is not running
In MQTT viewer i don’t see the plugin.
What do I wrong?
When I start SofarSolarMQTT receive this error:

How can I resolve?
I have this same problem.
Trying to run rs485 logger on my Sofar Solar 8.8 KTLX-G3 but looks like G3 series has a different registers. How to fix that? Here you can find registers received from Sofar support: docs.google.com/spreadsheets/d/1p6p7n8-V2jlFid3FPPk5L4Sn4-tOWscQwpkahq5jRbs/edit#gid=157762751
Currently I can see just “0” value for every entity
And this is the output from the logs. So looks like modbus communication is established correctly
For example:
“Total Energy” in pawelka’s project has address 0x0015
which address should I provide to let my logger reading a correct values?
EDIT:
Just found solution. Registers provided by Sofar support are in DEC. It just need to be converted to HEX.
For example PV_Generation_Total is 0686 (dec) = 0x2AE (hex).
Just changed address from 0x0015 to 0x2AE and finally, the correct data is uploaded into Home Assistant

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?
