Remote access to growatt inverter by esp32

stefboss59 · December 30, 2025, 2:08pm

Hello,
It is my first topic, to Ask for help.

I’m trying to connect my growatt inverter (spf 5000 es) with an esp32 (esp32dev) with the rs485 connector.
So i add a max485 to ttl to be able to comunicate with my inverter.

For the moment i’m still not able to get information from esp32.

I make a configuration over esphome, my esp32 is well discovered and can be accessed by OTA.

First question : is my growatt inverter able to communicate with my battery by CAN and also with my esp32 with RS485 simultaneously?

I would like to keep my usb dongle wifi shine s to communicate with growatt server without modification (as my inverter and my dongle under warranty).

What i did :

use GPIO16 and 17 as TX/RX connectors.
use GPIO4 as sens detector (as max485 is not able to detector auto-sens)
use GND as ground for my MAX485
use VIN as +5v for my MAX485
on my MAX485 i did connect pin 1 and pin 2 of RS485 câble coming from inverter

In the logs i still obtain “no respond”

Can someone help me ?

Please, please use the code format tags because how the code is added now is useless.
Same goes for the log file.

stefboss59 · December 31, 2025, 12:32pm

Can you tell me how to do so ?

Karosm · December 31, 2025, 12:49pm

Also, how is your wiring? Where does gpio16 connect? Where gpio4? How long, soldered or jumpers?
You should power the max485 at esp32 operating voltage, 3.3V.
Did you try to invert RS485 lines? How long are they? Do you use termination resistors?

stefboss59 · December 31, 2025, 1:32pm

The connector GPIO16 is connected to RX on rs485 and the connector GPIO17 to TX, yes i tried to invert them.
The connector GPIO4 is connected on both sens transmit and receive connectors to rs485

I don’t insert a resistor between them, should i do ? If so on which pin and for which resistor value?

For the moment everything is connected by jumpers about 20 centimeters.

The MAX485 is powered by 5 volts from esp32 and is lighting.

The answer is in the FAQ of this forum.

stefboss59 · December 31, 2025, 1:53pm

Here are some pictures of testing plateform.

Karosm · December 31, 2025, 1:56pm

Common max485 converters without automatic flow control usually have pins DI and RO… Yours not?

Depends on you RS485 wiring length, if it’s short, keep it without termination for now.

And Esp eventually frying. Go with 3.3V (or carefully add level shifter).

Also, where did you get those register addresses, they don’t make sense to me. Do you have protocol sheet for your model?

stefboss59 · December 31, 2025, 1:57pm

i modified the logs and the configuration respecting format.

stefboss59 · December 31, 2025, 1:58pm

yes they do have DO and RI.

when you say to insert a resistor it is on every connector ?

i will try with 3.3V instead of 5V, i did connect on 5V because merchandiser told it was under 5V.

register address have been found under some configuration describe in this forum in another topic, but, effectively from some body like me where it wasn’t working…

Karosm · December 31, 2025, 2:00pm

So where is your gpio16 connecting then…?

stefboss59 · December 31, 2025, 2:08pm

GPIO16 ---- RO
GPIO17 ---- DI
GPIO4 ---- DE+RE

i connected to 3.3V instead of 5V it is lightning also, but still not value in HOME ASSIST.

Karosm · December 31, 2025, 2:20pm

ok, that part is correct

You are far from that, stay with esphome logs. 3.3V power doesn’t solve your problems, but it prevents your Esp dying.

Two things now:

your registers don’t match with this, so do you have some other reference to spf5000 register map?
https://watts247.com/manuals/gw/GrowattModBusProtocol.pdf
this is from one spf5000es project in github:
“According to SPF5000ES User Guide RS485 pins to be used are 1 and 2 but I find out that pins are 8 (RS485B) nad 7 (RS485A) are the one used.”

stefboss59 · December 31, 2025, 2:36pm

i saw this topic telling that pin 7 and 8 from inverter where ok instead of pin 1 and 2, in my configuration book it is written that pin 1 and 2 should be use to communicate from RS485, but i also tried to use pin 7 and 8.
This triying happened in a older session and wasn’t working.
i will retry now.

and i will try to match the modbus protocol you gave to me.

if i take an example (extracted from my configuration) :

- platform: modbus_controller
    name: "${device_name} PV1 current"
    **address: 4**
    register_type: "read"
    unit_of_measurement: A
    device_class: current
    icon: mdi:flash
    value_type: U_WORD
    accuracy_decimals: 1
    filters:
    - multiply: 0.1

the register address to use is in bold in this example ?
and should have been :

stefboss59 · December 31, 2025, 2:42pm

or maybe :

stefboss59 · December 31, 2025, 2:55pm

I make some change with bus address modified and i’m compiling to deploy and see if some values are now right, i will let you know about the issue

stefboss59 · December 31, 2025, 2:59pm

here is the result :

Note: The reported total sizes may be smaller than those in the technical reference manual due to reserved memory and application configuration. The total flash size available for the application is not included by default, as it cannot be reliably determined due to the presence of other data like the bootloader, partition table, and application partition size.

I would expect the range from 0 to <100 is correct.
If I was you I would remove all sensors except one (or few) until you get response. You likely need to try both, contacts 1/2 and 7/8 to A/B and to B/A (4 combinations altogether).
