X3-MIC/PRO

[CristiXP]

Does this integration work with the X3-MIC/PRO as I have installed it, and I get unknown everywhere. Any ideea how to fix this?

Thank you,

Cristian

Also does this correct your Serial?

  - name: SolaX
    type: serial
    baudrate: 9600
    bytesize: 8
    method: rtu
    parity: N
    port: /dev/ttyUSB0
    stopbits: 1

    sensors:

    - name: SolaX Serial Number
      slave: 1
      address: 768
      count: 7
      data_type: string
      swap: byte

[CristiXP]

Any ideea where should I add them exactly? This is from my config yaml.

You shouldn't need to declare each one as a sensor, they should inherit the main sensor

template:

[CristiXP]

With the part of my template, it is working. But when I am adding your part, I am receiving an error:

template:
  - sensor:

      state: "{{ states('sensor.solax_today') }}" 
      unit_of_measurement: 'kWh'

      unit_of_measurement: 'kWh'
      state_class: total_increasing
      device_class: energy

When I add this it brakes it

- name: solax_pv_voltage_1:
      friendly_name: "SolaX PV Voltage 1"
      unit_of_measurement: V
      value_template: "{{ states('sensor.solax_group_i1').split(',')[0]| float / 10 }}"

Took the : out, it says that code is ok... but when restarting it, the template brakes.

[wills106]

Sorry remove the colon ( : ) at the end of each name.

- name: solax_pv_voltage_1: 
should be
- name: solax_pv_voltage_1

- name: solax_pv_voltage_2:
should be
- name: solax_pv_voltage_2

etc

[CristiXP]

Removed them already, but after restart it brakes the template

.

[wills106]

You are using a very different config style to me, so I am finding it difficult to adapt my style to yours. Maybe you do need to declare each one of your template as a unique sensor?

Are you able to https://github.com/wills106/homeassistant-solax-modbus/releases/tag/X3-Mic_Test Does it report your Inverter as unknown and with the serial number the correct way round? It still wont give you any values, but at least it will confirm if it's reading the Serial correct.

Now I have confirmation that the serial is at 0x300 I am best working on updating the integration, yaml is too frustrating at times.

[CristiXP]

Updated the Solax Modbus integration from HACS right now. This is what I have in log

s

[wills106]

If you change X3-Mic Test is should read correct.

[CristiXP]

Where I should change that? Or from where?

[wills106]

Did you press update in HACS for SolaX Modbus and restart? If you have, remove the Integration from the Integration page and readd it. Hopefully when you look in the log it will give you the following: unrecognized inverter type - serial number : MP153TGAXXXXXX

[CristiXP]

Deleted the integration, restarted HA, installed again, restarted. Same issue.

[wills106]

Do you still have the modbus config in your configuration.yaml? If so remove it all andy try again. You can only have a single connection to your Inverter.

[wills106]

O wait, I have missed something out of the test file.

[CristiXP]

Took it out. Same thing

[wills106]

Try "X3 Mic Test 2" when it shows up in HACS

[CristiXP]

It shows version 0.5.8 not Mic Test 2... installing right now.

[wills106]

If you can't see the Mic Test 2, click on SolaX Modbus in hacs then the 3 dots at the top, then Redownload and select show Betas

[CristiXP]

I have downloaded the Mic Test 2

The modbus was taken out from my config file. Installing the integration, restarting HA and still shows unknown.

[wills106]

Are there any other logs regarding SolaX?

[CristiXP]

These are the logs regarding solax

.

[wills106]

That initial read for serial. What's the full error?

[CristiXP]

[infradom]

Sorry for coming with this remark so late: when using a RS485 to USB adapter the solax_modbus integraton only supports baudrate 19200 right now. People using other baudrates use a RS485 to Ethernet adapter. Can you modify the baudrate on the MIC to 19200 ?

[wills106]

Ahh I forgot all about that!!! I'll change the Test Mic to v3 with the Baudrate hard coded. At least we can see if the Integration can read your serial or not.

[CristiXP]

Ahh I forgot all about that!!! I'll change the Test Mic to v3 with the Baudrate hard coded. At least we can see if the Integration can read your serial or not.

This is what I tested manually till now...

[infradom]

we could add an optioan config parameter for baudrate, but I prefer people use a waveshare like Ethernet adapter (due to the other warning and the relatively low cost)

[wills106]

@CristiXP Can you see if X3 Mic Test3a will give you your Serial number in the logs?

[wills106]

I agree Waveshare seems a much better option.

[wills106]

We are getting somewhere now, not sure why they have decided to reverse the byte order on the X3 Mic?

[infradom]

I believe that was not needed, and the normal version should do fine if you add MP* to the configs We got confused with the modpoll tool that required the byte swap

[wills106]

I haven't byte swapped the X3 Mic Test3a, that's how the Inverter has responded.

All I changed was the Baud rate and the address from 0x0 to 0x300

[CristiXP]

If I am doing it like this, I have retrieved this data: Onlye by adding slave: 1 to your sensors. Probably the temp is not 230 degrees... and needs adjustment or not sure that 1028 is actually temp. The rest of the values, are correct.

[infradom]

All I changed was the Baud rate and the address from 0x0 to 0x300

Ok, sorry , I did not follow the discussion with much attention as I was concentrating on another project

[wills106]

Temp is 1037 not 1028, I skipped some registers out on that Template sensor that split the group read.

[CristiXP]

1028 is probabbly the PV1 Power W with diff scale.

[wills106]

1028 is meant to be grid voltage, but scaled by 0.1 so I doubt your grid voltage is 23.3v

Does PV1 voltage and PV2 voltage match what you expect?

1044 and 1045 are your PV1 & 2 W doe they match up with the LCD on your Inverter?

You might find all of it needs byte swapping!

[CristiXP]

1028 was showing 233 with a scale of 0.1, so it's correct then for grid voltage. Restarting right now and let you know. Everything is correct. 1028/1029/1030 are values for R,S,T phase current.

1044/1045 also show correct values.

[CristiXP]

[wills106]

Ok so it must just be the Serial that's Byte Swapped then.

I need to finish off support for Dry Contact on the Gen4 Hybrid then I can start looking into properly supporting the X3 Mic in the Integration, as the search for a Serial number will need modifying.

We will need an "if statement" that if it can't find a serial at 0x0 look for one at 0x300

Then it needs to read all of the sensors in a different location to the other SolaX inverters.

[CristiXP]

Till then, can you please provide me a list of all the adresses, so I can add them manually? Thank you.

[wills106]

I promised I wouldn't share any documentation. But you can fill in the blanks with this:

Pv1 input voltage 0.1V Pv2 input voltage 0.1V Pv1 input current 0.1A Pv2 input current 0.1A R phase grid voltage 0.1V S phase grid voltage 0.1V T phase grid voltage 0.1V R phase grid frequency 0.01Hz S phase grid frequency 0.01Hz T phase grid frequency 0.01Hz R phase output current 0.1A S phase output current 0.1A T phase output current 0.1A Temperature 1°C Output power 1W Inverter status R phase output power 1W S phase output power 1W T phase output power 1W Total power of dc1 and dc2 1W Power of Dc1 1W Power of Dc2 1W

[CristiXP]

It's enough for me. For 1043, it is showing 0. Is there another address for Total power?

[wills106]

It's meant to be that one. No saying it actually works or not? The docs are not always accurate.

None of the other Inverters actually have that register. I have to basically do a template sensor within the integration to combine PV1 Power & PV2 Power together.

[CristiXP]

No problem. All is working fine. Thank you for your support! Hopefully you will manage to update and correct the integration.

Thanks alot!!!

[wills106]

@infradom Is this correct https://github.com/wills106/homeassistant-solax-modbus/blob/d8642af5cb59c993b3709ddc06d121b6cbe83f51/custom_components/solax_modbus/const.py#L50

Or should it be be a different Value?

[CristiXP]

Does it have any address for the feedin power to the grid or taking from the grid? Or the actual house consumption? Or those are taken from the smart metter and not exposed? Or calculated form Output and Total power?

[CristiXP]

No adress is measuring kWh? There are missing feedin energy,consumed energy, energy today and energy total.

[wills106]

On the Hybrids there is a calculation within the Integration:

if   feedin_power > 0: self.data["grid_export"] = feedin_power
else: self.data["grid_export"] = 0
if   feedin_power < 0: self.data["grid_import"] = abs(feedin_power)
else: self.data["grid_import"] = 0 
self.data["house_load"] = inverter_load - feedin_power

Does your Output Power match either 683w or 771w in your picture?
