Remote access to growatt inverter by esp32

ESPHome
21

I tried every contacts and inverts 1/2 and 7/8 with a short list of sensors, they still appears unknowned.

Configuration :

That’s not important. What you need is response. Modbus devices supposed to respond in any case if they receive request in correct slave address. If your register address is wrong or CRC doesn’t match they still give exception response. Which you only see on esphome logs, not on HA.
Check your wiring for loose connections etc, everything has to be rock solid.

Also, the protocl sheet mentions that min interval for requests is 850ms. Add this to your modbus_controller:
command_throttle: 1s

And you didn’t reply, how long is your RS485 wiring?

And if I can anyhow read your terrible photos, it looks to me that white wire is between RO and TX2(gpio17), which is incorrect and not what you wrote here.

25

The wiring RS485 from inverter to TTL converter is aproximatively 150 centimeters.
Do you think it’s too long?

When i used it to communicate between battery and inverter it was 300 centimeters long and communication was good (now i passed it to CAN with the same câble, just changed port and configuration on inverter)

26

So i should invert RO and DI on MAX485?

27

It was supposed to be like this…

Rs485 length of 150cm is ok, you don’t need to bother with terminations. I ask because otherwise after 90 posts I find out that it was 150meters…

28

IT WORKS !!!
you were right, the gpio16 and gpio17 were inverted.
I used pin 1 and 2 from inverter to TTL and i got values in home assistant

I will configure every sensors, make a schematic and give back to the forum my configuration.

Thanks a lot.

29

You are welcome. If you ever replied correctly to my first question, you saved lot of time…

Now read the protocol sheet well. Most of the values are double registers and you need to set them correctly.

For example if you need “output active power”, you read register 9 set as
value_type: U_DWORD
This way 9 and 10 are combined together.

hello, as promised i give you my defintive cabling diagram :

and my ESPHOME configuration, for the moment there is both Bluetooth for my apexium battery (survey, control, program) and RS485 to TTL for my hybrid inverter GROWATT SPF-5000-ES :
