Solax X1 Mini with Limiter and SDM72 Smartmeter

Hello,
I looked at the Tread #20/32 but I don't understand what I need to adjust for my solution. I would like to control the Soalx inverter with the power meter. I'm using an SDM72 which is not from Solax but which counts 3 phases. Accordingly, the SDM72 also has consultative registers, as is the case with the SDM230 with the 30013 register. For the SDM72 it would be the register 30053 Total System Power. What does the digestion of the Modbus have to look like? AB from the Sloax parallel with Smartmeter and the esphome? The ESP Home only uses one UART. Does the ESPHOME convert any data between smartmeter ans solax inverter?

Many thanks in advance.

Greetings Dirk

Support for solax X1-1.1-S-D(L)

Hello,
I have a Solax inverter Model X1-1.1-S-D(L) version Manager.1.07 Master: 1.08 to which I have connected an RS485-to-TTL module and a Wemos D1 mini pin TX (GPIO1) and RX (GPIO3) . Unfortunately I cannot recover the data from my inverter. See logs:

With my oscilloscope I see signals on the TX / RX pins and I see the TX led of RS485 converter blink periodically.
It looks like my inverter modbus is not active. I tried passwords 2014 and 6868 but I have no option for modbus, only DRM (disable)
Could you help me ?`

Add ESP8266 config example

Add documentation how to use the `solax_meter_gateway`

The solax_meter_gateway can be used as SDM230-MID-SOLAX (SDM230 with solax firmware) drop-in replacement. The Solax inverter with export control: meter enabled setting will request the current power consumption periodically. The solax_meter_gateway responds to this request with a sensor measurement retrieved from another sensor/device.

How to enable the "export control: meter" mode:

Settings -> Pin: 6868 -> Export control -> Meter enable

See #32
See #20

Probably more Solax inverters are supported. This feature isn't limited to the Solax X1 series.

Indicate if the inverter is unavailable

At the moment the mode is 0 ("waiting") at night. We could introduce a new mode (-1) to indicate the device is unavailable.

Rewrite from yield to async/await

Looking for SDM230 protocol details

Maybe you have communication protocol Invertor <--> Meter

I am investigating:

Solax X1 mini:
That ask every second like a ping. That works.
send solax: b'\x01\x03\x00\x0e\x00\x01\xe5\xc9'
meter SDM230 not from Solax anw: b'\x01\x03\x02\x00\x00'

send solax: b'\x01\x03\x00\x0b\x00\x01\xf5\xc8'
meter SDM230 not from Solax anw: b'\x01\x03\x02\x00\x00'

But that probably Solax request Data:
send solax: b'\x01\x03\x00\x08\x00\x04\xc5\xcb'
meter SDM230 not from Solax anw: b'\x01\x03\x08\x00\x00\x00\x00\x00\x00\x00\x00'

Meter answer: 00 00 00 00 00 00 00 00
I do STM32 rs485 gateway, but need to know from Original Solax Meter what answer.

Maybe someone has that information? Thanks.

Meter functionality

Hi There.
I stumbled upon this project, and I´m curious if there is some "external meter functionality" planned?

As you know Solax inverter support external power meters in order to be able to handle export control.
I have a larger PV set than allowed, thus I want to limit the power which gets exportet to the grid.

On the other hand I do not want to always limit the inverter output power because I want to use full PV power when some consumer in my House demands it.

As I have already a power meter installed (no modbus/not supported by Solax) and it´s values are available in my home network, it´d be great to have the possibility to feed these values to the Solax inverter.
Then I would be able to perfectly limit the exported power to the grid.

Feature Request: Override Switch for Export Control

Discussed in #60

^{Originally posted by Sven177 December 8, 2023}
Having an Override Switch for the Meter Gateway, to toggle between either listening to an existing sensor´s value to determine the current power demand, or using a fixed value (like 500W) would be nice.

This would allow to "disable" the export control function on the Meter Gateway side whenever needed, while leaving the actual export control function of the Inverter (and according settings) still active and untouched.

(Hope this is the right way for a Feature Request - first time for me) 😉

Add flow control pin support

Hey guys,

thank for this modules. In my case I try to use it with a Solax X1 mini 1.5 V2.
And I only receive the text which is mentioned in the title.
May anyone has the same issue and can help me to fix it.

regards
frank

Still problems with sporadic meter faults

Hi Sebastian,

the export control is basically working, and I am using 2x D1 Mini Boards for 2 separate inverters.
But sometimes, I get the meter fault error thrown by the inverter and I haven´t yet figured out why.
I found, that the source sensor for power consumption (Shelly 3EM) sometimes takes 10-15 seconds to update values regarding power consumption. To get around this, I added an heartbeat filter to the code, to send the source value to the power demand sensor every (tried) 3 or 5 seconds, even if the power consumtion sensor hasn´t been updated in between.

But despite that change, sporadically the meter fault still shows up.
Any ideas what would cause this? Could it be related to using 2 Boards at 2 Inverters sharing the same code?

Out in the field currently (work related), will be back on Thursday to provide according logs or increase the Log Level

Temperature reading wrong when temperature is negative

The temperature reading of the inverter seems to be a signed value, but the component interprets it as unsigned.
This results in an overflow when Temperature is below 0°C.

Meter fault (solax-meter-gateway)

Hallo,
nachdem ich endlich dazu gekommen bin das gateway live in betrieb zu nehmen, habe ich festgestellt, dass der Umrichter immer auf "Meter fault" stehen bleibt.
Wenn ich das Log richtig interpretiere, bekoomt das Gateway die Werte vom Meter und kommuniziert auch mit dem Solax Umrichter. Warum geht der Umrichter nicht in die Produktion.
Solax Umrichter ist unter Erweitert - Einspeisebegrenzung auf Meter gestellt und in der Begrenzung auf 20000 für unbegrenzt, oder 0 auf keine Einspeisung gestellt. Der Umrichter bleibt aber mit fehler ausser Betrieb.

Support for SolaX X1 (ModbusRTU via RS485)

From the readme I understand that the SolaX X1 (not mini) isn't supported, but is there any reason to believe this project won't work with that inverter?

can't connect to X1 Mini

I'm in a simiar position to the one another user was in here: #33

The output is the same, with this block repeated every few seconds:

I have checked the wiring on my RJ45 cable against the RS485 pinout in the X1 mini installation manual and everything's right. Multimeter says there's continuity on A+, B- and GND.

The light on the HW-219 flashes repeatedly so it does seem to be getting communication from at least one side. I've tried both GPIO1/3, which are my D1 mini 32's TX and RX pins, and GPIO16/17.

I was able to sign in to the advanced device menu through the Solax cloud with password 2014 and set the modbus support to "enable" and modbus address to "1".

I tried powering the HW-219 with 5v instead of 3.3 to see if a little extra power would help, but still got nothing.

Any ideas what to try next?

Lookup address via serial number from device object

https://github.com/syssi/esphome-modbus-solax-x1/blob/main/components/modbus_solax/modbus_solax.cpp#L105

Add additional sensor for measured faults

  // register 32: Grid voltage fault in 0.1V
  // register 34: Grid frequency fault in 0.01Hz
  // register 36: DC injection fault in 1mA
  // register 38: Temperature fault in °C
  // register 40: Pv1 voltage fault in 0.1V
  // register 42: Pv2 voltage fault in 0.1V
  // register 44: GFC fault

Add operation mode "Standby" if there are no Solax requests

Add Solax X1 Mini G3 support

i have a problem with the Solax x1 mini G3 with following errors

Similarities to SolarEdge SunSpec protocol ?

Anyone know is there any similarity with the Solax protocol over modbus to SunSpec used by other solar inverters including SolarEdge ?
Reason for asking is the possibility to fork this into a ESPhome-modbus-SolarEdge project.
