Unrecognized Inverter - SolaX

[wills106]

If you get the following error in your log:
"unrecognized inverter type - serial number : {your_serial_number_here}"

Please list below the first 6 digits here including the Inverter type and kW rating and which plugin you got a response with.
I can then add in your Inverter.
Please do not raise an issue in addition.

If you get unrecognized XYZ inverter type - serial number : unknown you don't have a working Modbus connection.
Don't raise an issue, this isn't a fault of the Integration.
Either use one of the existing discussions or start a new one, don't comment in this discussion about unrecognized XYZ inverter type - serial number : unknown

Hi, here is it: Solax X3 Hybrid 10.0M, ser. n. begins: H34B10

[wills106]

How are you trying to connect? RES485-Ethernet, RS485-USB, PocketWiFi? You don't have a working Modbus connection.
If PocketWiFi have you read https://github.com/wills106/homeassistant-solax-modbus#solax---pocketwifi-readme

[MartinPicman]

I use modbus connection over TCP by Waveshare (RES485-Ethernet) for more than 5 month. Wifi pocket was very unstable.

[MartinPicman]

hmm, smthng magic inside of HA modbus. I have my own integration of modbus for recuperation unit which is not supported. Last change I did on Wednesday. And yesterday morning I saw 1st trouble with Solax. I restarted HA and it was ok. Then I appied HA core update and then your update to 9.3. And that raised an issue. Now, after our discussion, remove my own modbus lines in configuration.yaml, restart HA and TaDa .. Solax is back. I put my modbus integration back to configuration.yaml, restart HA, and both are still running :-). I'll check the HA core updates what they did ...

[wills106]

Might be related to #528

[MartinPicman]

Hi, HA 2023.9.2 and your Solax modbus integration 9.4 fully solved this issue.
Thanx a lot.

[romankysely]

Hi wills106, please add this SN to invertor.
Thank you and let me know how can I buy the coffe to you. You are doing great job.

Could You react Will? Thank you, I sent you some cups of coffes :-)

[wills106]

Have you seen #528 HA 2023.9.1 introduced a pyModbus change. The Beta Integration 2023.09.4b5 has resolved that. So I would update to that first.

Edit: Your Inverter is already supported. But you don't have any communications between your Inverter and Waveshare. If 2023.09.4b5 doesn't resolve your connection issue, double check your settings vs the Wiki.

[romankysely]

Thank you Will. The problem was in modbus addresses at invertors. I had Master and Slave both on the number 1. When I changed Slave modbus address to 200 and gave RJ45 to COM of the Slave I have got data immediately. May be good hint to Wiki in case of more invertors. Interesting is that both Master and Slave were working fine on the Modbus with same address before.
The second problem probably was in SolaX Invertor Modbus modul in Configure/TCP/IP Parameters. There I choose Modbus RTU over TCP instead Modbus TCP. BTW it seem that is doesn't matter where is RJ45 connector connected. Master ort Slave COM port. Are the Entities are consolidated for both invertors when I have checked Parallel Mode (Master-Slave) option ? Many thanks for help.

Hi, here is it

HA version: 2023.9.2

Inverter: X3-Hybrid-G4

thx ;)

[infradom]

Did it work before 2023.9.2 ?
Which adapter do you use (Ethernet, USB, ..) ?
Have you tested removing the integration, reboot HA and reinstall the integration ?
Do you use other Modbus devices ?
It is hard for us to help without this information

[Maska9]

yes everything worked before installing HA 2023.9.2 (Solax modbus was version 2023.9.3).
I am connected via WiFi dongle and modbus/tcp.

After installing HA 2023.9.2 the modbus stopped working and shows the mentioned errors.
I removed the integration, tried to install version 29.9.4b5 and then found this post where to send 6 numbers from SN.

I don't have any other modbus devices

[wills106]

Your Inverter is already supported as it's previously worked.

I would install Integration 2023.09.4 that I released earlier today. Also check the Readme for advice on trying to get the PocketWiFi working again. They aren't exactly the most reliable connection method.

[Maska9]

Thanks a lot for the direction.

I removed the integration again, installed version 2023.9.4 and disconnected pocketWifi for a minute. After the new addition, everything works as it should again.

Hi wills106, all,

I have a Q.Cells QHome ESS Hyg G3, aka Solax X3.
I'm also struggling now to get modbus working with my waveshare after it had worked already ~6weeks ago.
The inverter was turned off for more than a months because my energy meter is not yet replaced.
After turning it on I only get home assistant with modbus working via the wifi dongle.

Last time I got it working was when after several tries also wifi didn't work anymore and I found a forum comment from wills,
that the inverter allows only one modbus connection. After a power cycle I was able to connect to the waveshare and it
worked for weeks.
This process doesn't succeed anymore and I just tried a power cycle even with wifi dongle disconnected.
Any hint/idea?
My serial begins with H34C10

PS: Latest Solax integration updates and HA updates have been installed.

thanks and best regards,
Thomas

Hi Wills106, thank you for your efforts

I try to connect My Solax X3-Mic-5k-G2 with the following error message: "unrecognized inverter type - serial number : MC205TI819XXX"

please add this Inverter

Thank you and best regards,

[bennybauer1978]

It is a three phase, 5kw Inverter. Using latest solax Inverter modbus from hacs

[wills106]

Thanks just added into 2023.11.1

[jankorous]

Hey, I have a question - is that solved? Because today I've updated HA and Modbus module and any entity's lost...

My SolaX X3 10K G4 Hybrid, SN SRBP6C...

[jankorous]

Ok, I will wait until it get solved... or buy another way to connect inverter with HA

[cewbdex]

PocketWiFi upgrade is described in readthedocs well, even fw repo, you most likely did not read the version properly, just look at pages Will sent you (I have never seen dongle with the oldest fw, they are very rare). Make sure you have a static IP set. If you didn't look, it's https://homeassistant-solax-modbus.readthedocs.io/en/latest/solax-faq/

PS. Will, can you turn off the Wiki tab in repo settings, so I can refer to RTD as wiki? It should not erase it, just turn it off.

[jankorous]

After a second HA hard reboot, the modbus started providing data again. I thought multiple restarts only solved problems with windows os...

But... The firmware is downloaded, but I don't know if I will update because there is a saying: if it works, don't fix it.

[cewbdex]

Well obviously there is some kind of problem, so it does not work properly, probably something about your setup. With this philosophy we would be still using rocks and sticks.

[jankorous]

Well, I think technological progress depends on people's laziness... :D Anyway, I will go through the settings after updating the module and the inverter

[zidekm]

would be possible to add my inverter.

Hello Mr.Wills106 and thank you for your work with this integration SW.

I'm trying to connect My Solax X3-Mic-6k-G2 with HA SolaX Inverter Modbus v2023.11 but I'm getting the following error message: "ERROR (MainThread) [custom_components.solax_modbus.plugin_solax] unrecognized inverter type - serial number : unknown"

Can you please add this inverter.

Thank you

[wills106]

Your Inverter is already supported, you have no working Modbus communications with the Inverter

[abaretta]

Hi,

I have a Solax X1 Boost 4.2 (X1-4.2-T-D) with SN: XB4221XXXXXXXX which is connected through RS485. The integration is able to pull the 'registration number' from the invertor which leads me to believe the modbus connection is working. However I am guessing the registers are different as for the other entities the status is 'unavailable'.

If support could be added for this type of inverter it would be awesome :-)

Thanks in advance.

[wills106]

Do you know what address the Inverter is returning the Serial number on?

Do you get an error that it failed at address 0?

homeassistant-solax-modbus/custom_components/solax_modbus/plugin_solax.py

Lines 65 to 68 in 1cef574

	except Exception as ex: _LOGGER.warning(f"{hub.name}: attempt to read serialnumber failed at 0x{address:x} data: {inverter_data}", exc_info=True)

	_LOGGER.info(f"Read {hub.name} 0x{address:x} serial number before potential swap: {res}")
	return res

Depending on how you have setup your logger you should also see

[custom_components.solax_modbus.plugin_solax] Read SolaX 0x0 serial number before potential swap:
Or Read SolaX 0x400

[abaretta]

Thanks for the quick response 👍 It turns out I had a conflict between two identical RS485 converters. It seems at some point the Solax integration was at least able to pull the registration number and create a hoist of entities, but that appears to have been a fluke. I can't reproduce it. Anyway, I resolved the USB conflict and am able to poll the inverter directly from the server (using Solaxd):

2023-12-08 10:41:05.290 [TRACE] ComTx: AA 55 01 00 00 0A 11 02 00 01 1D
2023-12-08 10:41:06.290 [TRACE] ComRx: AA 55 00 0A 01 00 11 82 32 00 12 00 00 09 AB 04 E1 00 01 00 01 00 08 08 E3 13 89 00 31 FF FF 00 02 29 18 00 00 56 4D 00 02 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 08 22

The ID of the inverter appears to be '00 0A' corresponding to device 1 on the bus, correct? I now get the following logging from the HA integration (running in docker with a device mapping):

2023-12-08 11:06:03.117 INFO (MainThread) [custom_components.solax_modbus.plugin_solax] Read SolaX 0x0 serial number before potential swap:

Thanks!

[wills106]

It's possible you still don't have a fully working Modbus connection if the Integration has previously returned your Serial Number correctly.

You can assign the USB-RS485 by the usb-id #513 (comment)

Which gets around the ttyUSB0 / ttyUSB1 issue you can have.

[abaretta]

I do indeed have the correct device mapping based on the device ID. However, what is different is that the inverter is now connected together with an Eastron SDM220 to the same USB RS485 converter, exactly like the setup mentioned in the X1-Boost, X1-Mini, X1-Air modbus documentation thread. I can successfully poll both the SDM220 as well as the inverter from the server through the same USB device.

There's an error popping up in the log that I didn't mention as it appeared to occur after the failed serial number detection, but now I notice it happens right before/during the serial number detection. I don't know if that's an issue or not for the setup process?

Never mind, I see this is a known issue (nr. 2, the async issue, I have added the logging filter).

I now get the error you mentioned above:

2023-12-08 20:07:34.613 ERROR (MainThread) [custom_components.solax_modbus.plugin_solax] unrecognized inverter type - serial number :

And I think solaxd connect to the inverter at address10 not 1 (00 0A), although it doesn't seem to make a difference when I use that as the modbus address.

Can you confirm this ?

If the Waveshare is this version, it will work if setup correctly and is the prefered method.

[Womble1962]

I have pinged my Waveshare in the terminal window in HA and it returns as connected

So looks like my Waveshare is connected to Homeassitant ok

Now I have another port on my inverter that the modbus reader is plugged into by RJ45 this is for the meter (C on the manual). I f I unplug that I get an inverter error.

Yesterday I plugged my PC into Port 485 on the inverter directly with a network cable and the inverter shut down, so the 485 port on the inverter must do something.

I have my Waveshare plugged into the port arrowed H RS485

My batteries are in I

My Modbus meter is in C External meter Port

I have just bought new network cables and replaced them 3.5 metre cable from inverter to Waveshare, 0.4m cable to Wifi Extender

[wills106]

Yesterday I plugged my PC into Port 485 on the inverter directly with a network cable and the inverter shut down, so the 485 port on the inverter must do something.

You are lucky you haven't damaged your PC or Inverter doing that.

Just because they use an RJ45 connector doesn't mean they are Ethernet.

[Womble1962]

I realise that now.

I meant to plug the Waveshare into the network port to check that the wifi was not stopping us connecting, but plugged the inverter cable in by mistake.

We were trying to get our Eastron 100 amp meter to work as well but I think we are going to a ct type instead as it is not safe how it is installed now as the 60amp meter is basically the fuse as we have a 100 amp fuse outside. Should never of been installed like that.

Does this help?

I have changed my baud rate on my inverter and the port to use and set these up in the Waveshare

Should my destination be set to 192.168.1.38? with 4196? and not 502?

When you change the baud rate in the inverter do you have to shut it down and restart it?

Hi,
i'm deseperate :( Because the led is blue when HA read information. I check in the inverter and the speed is ok (at 9600). In the web portal of rs485 eth (B), i check and configure with the same . But i have the same message.

Could you help me ?

[cewbdex]

iir the baud rate on inverter might be for power meter, see https://homeassistant-solax-modbus.readthedocs.io/en/latest/baudrates/ for one that might work

[darksider90]

Yes ! it's ok. The pb is on the number of the modus ID. In the inverter, it's at 2 :/ . After replace by ID1, rock and roll :)

For information, if you want to modify this, it's an obligation to connect with a installator password : 2014

Thank you for your Help

Wonder if I change mine from 1 in the invertor to 2 it might work for me.

I saw you added „mppt3“, too. Do you think this solve the pv3 issue?

I can test, but at the moment I’m running a edited fork of your code.

[wills106]

Not yet. I don't have any docs for these new Inverters so I don't know what registers you need to read.

[wills106]

I have added in more support to 2024.03.42024.03.5

[wills106]

@simowNgithub @Krawuzzi
It looks like quite a few of the Selects and Number entities have moved to different registers on the Gen5 Inverters.
So I wouldn't make any changes to those yet.

Edit:
I have opened #813 to work on supporting these new Inverters.
