З приводу підключення RX/TX до USB , щось там наплутали. Так і спалить вихід можна. В середині інвертора до юсб підключений USB -> com перетворювач. Ніяких RX/TX там не отримать.
Я нічого не наплутав, у мене прямо зараз працює така схема. Перетворювач в самому usb-донглі, а не в порті.
У вас вийшло зробити комунікацію таким чином через USB WiFi порт?
Я всі комбінації A+/B- та Rx/Tx спробував, не працює
Яка саме модель інвертора у вас?

MUST pv18-5248 pro
Already tried that,, i will try another RS485 to UART board and update
I used this one, works ok: https://www.aliexpress.com/item/1005001621746811.html
I also connected it to the USB port of the inverter. It uses the same RS485 (at least on the PV1800 series, as far as I know), but additionally has 5V to power the ESP and adapter, so you don't need to use an additional power supply.
So, in my case, 5V connected to the ESP, GND connected to the RS485 converter board GND and to the GND of the ESP, and middle USB pins to A/B (not sure which one is which, try to swap if it does not work). The 3.3V from the ESP connected to the other side of the RS485 converter board to the VCC, RX/TX to the ESP and swapped, and the ESP GND to the board GND.Вітаю! Тобто ви підключили плату RS485 не до RJ-45 а до порта USB Type-A (позначений як USB WiFi) ?
Привіт. У вас вийшло зробити комунікацію таким чином через USB WiFi порт? Я всі комбінації A+/B- та Rx/Tx спробував, не працює
якщо питання до мене, то так, у мене вийшло.
Поки до HomeAssistamt не підключив, але віддалено оригінальним софтом Solar Power Monitor від Must я підключився через WiFi (ESP + esp-link) до інвертора Must PV18-3224.

Тобто це така сама solar2mqtt? У мене так і не виходить одружити з моїм anenji. 6500вт 48в. У нього на борту 232 та 485 порти, я правильно зрозумів, 232 до вайфай, у мене він є та працює (заводський) але додтаок та сервери ... це мрак. У мене також є налаштований та працюючий home assistant. 485 для підключення фірмових батарей? Я тільки сьогодні побачив цей пост, допаяв до esp8266 (nodeMCU) все як у вас, ткнув в 485 - нема (перетворювач у мене э). 232 - так само, також э саморобний перетворювач на max232 та заводський. Байдуже, тиша. Можливо є якісь інші распіновки? але ж живлення та земля співпадають у мене 4й 12в, 8й - земля. Це я про 232. У вас є схема та бінарний файл для вашого девайсу? Можливо є для 8266?
У вас вийшло зробити комунікацію таким чином через USB WiFi порт?
Я всі комбінації A+/B- та Rx/Tx спробував, не працюєЯка саме модель інвертора у вас?
MUST pv18-5248 pro
У мене такий же інвертор, все працює.
В червоній термоусадці модуль RS485 - TTL, посилання кидав вище.
Такий же інвертор, така сама RS485-TTL, на базі esp32 wroom32 (gpio 1/3 у якості tx/rx) - все перепробував, досі отримую
[21:33:24][D][modbus_controller:038]: Modbus command to device=4 register=0x6295 no response received - removed from send queue
для всіх каналів. Вже не знаю яку ще комбінацію спробувати.
UPD: ще отакий побачив ворнінг
[22:59:44][W][modbus_controller:027]: Modbus device=4 set offline
UPD: спробував інший rs-485-ttl та А/В брати з перших пінів RJ45, а не USB WiFi, результат такий самий

Я не читав ще про Wroom плату, але у мене була схожа ситуація з NodeMCU (ESP8266). Проблема у тому, що на платі для розробок NodeMCU вже є модуль USB-UART і він під'єднаний до RX/TX контролера. І виявляється що він постійно тримає RX в стані HIGH. Тобто використовувати RX пін напряму майже не можливо.
Можливо з wroom платою така сама засада ?

Дійсно, перекинув на інші gpio піни які вміють UART і запрацювало.
Велика подяка вам і автору конфіга!

Have additional experiments and results.
I use ESP-01 with latest ESPHome firmware + your YAML config. I chosed original RX/TX for communication with RS485 becouse ESP-01 have only this pins.
So , it works if I doesn't try to view LOGs from device.
If i try to view LOGs - Inverter are stuck and stop give parameters. And only one solution - restart Inverter.
So I suppose that LOG (Debug) use the same UART and thus stuck Inverter with flooded information.
I have changed UART for logging but withh no success ;(
I use such config, but only works if don't use LOG :)

There is a mistake in the code probably, adress should be 0x4, not 0x04
