X3 "nicht-Hybrid" about solaxmodbusgateway

[thakikka]

So, ich habe mich da jetzt mal als absoluter Laie versucht durchzukämpfen.

Die Änderung habe ich für "Solax-Mic" vorgenommen. Danach habe ich unten in der Befehlszeile mittels "platformio run" das Ganze erneut erstellen lassen. Dann habe ich aus dem Ordner .pio/build/ die Datei firmware.bin heruntergeladen und auf den Adapter als Firmware hochgeladen.

Hat offensichtlich geklappt?

Leider weiterhin keine Daten bei RawData, egal was ich probiere bei den Einstellungen.

[juwild83]

Hallo,
ich hab das für mich jetzt anders gelöst.
Habe auf ESPHome auf den "Adapter" geflasht. Die Adressen dann mit in die Konfiguration gepackt und kann alles jetzt mit Home Assistant auslesen.

[tobiasfaust]

Ich würde einfach mal behaupten das das Modbus Protokoll des X3 Hybrid sich zu deinem normalen X3 unterscheidet und dein WR nur Müll zurückgibt weil er die Anfrage nicht versteht.

Kannst ja mal zum Test die anderen verfügbaren WR aus der Auswahlliste ausprobieren ob bei einem etwas sinnvolles zurückkommt.

edit: nicht Solax x3 sondern bitte mal Solax MIC auswählen

[thakikka]

Klappt leider auch nicht. Spannenderweise wird der Modbusadapter selbst in ioBroker erkannt, aber es kommen einfach keine (lesbaren) Daten an:

In der SolaxCloud ist die Bezeichnung des WR übrigens "X3-MIC/PRO". Aber scheint mit "Solax MIC" als Auswahl leider auch nicht zu klappen.

You need to ask Solax support for the modbus register for your exact model and firmware and then compare it to the ones already supported by Tobias. Also you may need to go into the inverters settings and turn on Modbus RTU and set the address to 1 as they may not be correctly set by default.

[thakikka]

Thank you for your answers.

In the inverter settings, the address is already set to 1. In the meantime also on test to 2.

I have today written to Solax support with the request for a firmware update. I will write to them again and ask for a suitable modbus register.

[kommando828]

Tobias has included a selection of the Solax Modbus pdf's

https://github.com/tobiasfaust/SolaxModbusGateway/tree/development/docs

So once you have the one from Solax for your inverter and can check against these to see the closest match.

Their naming on the inverters and the model numbers on the inverters don't always match exactly which causes some confusion. Not including the Generation of the inverter is another issue.

[juwild83]

Hello everyone,

Has anything already happened on this topic? I also have an X3 inverter without a “hybrid”.
Best regards

[tobiasfaust]

Hi,
unfortunally - no.
you need the right modbus protocol description document before you are able to start

[juwild83]

Hello, I probably got the relevant protocols from a post from the “Photovoltaikforum”.
I just don't know enough about the subject and won't start changing the code now.

Best regards

Can you Upload it here please?

Of course I can do that

[juwild83]

I have the X3-10 myself. In my opinion this should fit:
Solax Power X3-MIC three phase inverter Modbus-RTU comms protocolV1.05 - public version

[kommando828]

Just be aware that Solax have several generations of each inverter but fail to identify the generation in some cases. So in this case the PDF you have pointed to is for a X3-MIC Gen1, in your zip there is also a PDF for the Gen2. So its worth taking a bit longer to do a check which Generation your inverter is.

[tobiasfaust]

As I saw in your documents, all MIC X3 types hold their live dataregister ap from 0x0400 by functioncode 0x04. So if you select Solax-MIC it should be fine basicly.
How looks the rawdata page if you select "Solax-MIC"? Please post a screenshot

solax.zip

I have now received an e-mail from Solax confirming that the firmware update has been installed as requested. The following files have also been sent to me. Is there anything you can do with them?

[thakikka]

(I also tried 9600 as Modbus Baudrate. Same result.)

[juwild83]

same for me

[kommando828]

The label on the inverter should identify the Gen with the exception of Generation 1, all other Gen's should have on the label G2/G3/G4 and so on. Also check the picture on the title page of PDF matches your inverter. For the X3-MIC there only seems to be Gen 1 and Gen 2 from what I can see but other types are at Gen 4.

[tobiasfaust]

I know that Problem. Your inverter Firmware is too Old that you cannot request 64byte in one Single request. Please try to change it.

please select the Master branch and check it out via gitpod (See Wiki Page)
Please change 0x40 to 0x16

"RequestLiveData": [ ["#ClientID", "0x04", "0x04", "0x00", "0x00", "0x16"] ],
After that recompile and Upload the new firmware.
If it works you can increase 0x16 in small steps

please be sure, your baudrate is in sync with your inverter settings

[kommando828]

Tips when comms are dead.

1. Check baud rate is correct, for X3-MIC G1 and G2 this is 9600 but be prepared to try other baud rates.
2. Swap the two RS485 wires around, not everyone labels them correctly, Janitza is one where this works,
3. Check the cable you are using is a good quality cable, some are copper plated aluminium, even solid copper fractures internally. I always use 24awg stranded copper wire network cable. This fixed my dead comms with an X1-Boost G3, I then hit the too many registers requested issue.

Hi, same problem here.
I've asked the support for a firmware update but they replied that is was already the latest version.

X3-MIC-10.0 TD

Please do the described changes to make sure that this is the problem.

[JMyrng]

Please do the described changes to make sure that this is the problem.

I can only find the "RequestLiveData" files in the dev branch, but I compield the new firmware. Is it possible to upload that over the web portal or should I do it via ESP32 Flash download tools?

[tobiasfaust]

If you uses the dev branch, you have to flash via ESP32 flash download tool (see gitpos wiki)
If you used the master branch, you can also use the web portal upload.
Currently I redesign the file handling, because that there are differences between dev and master

[JMyrng]

I currently only have access via network. So where can I change these settings in the master branch?

[tobiasfaust]

Wir müssen jetzt rausfinden wo es hängt!
Stell mal bitte LogLevel auf 5 (Basis Config) und poste mal bitte das Log welches auf der seriellen Konsole ausgegeben wird.

[thakikka]

Entschuldige meine Unwissenheit, aber muss ich dafür den Adapter an meinen PC anschließen? Oder lasse ich ihn am Wechselrichter? Ich habe in den FAQ gelesen, dass ich "hterm" installieren soll. Bin gerade offen gesagt etwas überfordert.

[tobiasfaust]

Der ESP muss an den WR (sonst kannst du ja keine Daten empfangen) sowie per USB an den Laptop (damit du siehst (-> über hterm) was vom WR am ESP ankommt).

[thakikka]

Danke für deine Hilfe, aber ich merke leider, dass ich hier an meinem persönlichen Skill Cap angekommen bin. Ich kriege weder auf dem Laptop noch testweise am PC eine Verbindung hin.

Ist der USB-Anschluss, an dem das Ladegerät hängt, auch der USB-Anschluss, den ich mit dem PC/Laptop verbinde? EInen anderen USB-Anschluss konnte ich nicht entdecken.

[tobiasfaust]

Ja genau, also anstatt usb zum Ladegerät gehts an den Laptop
Versuch dich mal mit Google schlau zu machen, da gibt es ganz viele , auch bebilderte, howtos wie man starten kann :)

[thakikka]

output_2024-01-31_15-15-08.txt

Ich habe es geschafft. Danke für deine Geduld.

Dummerweise hatte ich "Timestamps" aktiviert, aber ich denke, es ist trotzdem aufschlußreich. Nämlich das egal was ich währenddessen an unterschiedlichen Einstellungen probiert habe, es nie zu irgendeiner Ausgabe von Daten kam :(

Ich hatte weiter oben die ZIP-Datei hochgeladen, die mir von Solax zugeschickt wurde. Passt das denn so überhaupt mit dem Modregister?

[tobiasfaust]

Dein WR antwortet nicht. "No response"
Bitte überprüfe zuerst in den Einstellungen deines WR welche ModbusID und Baudrate dieser verwendet. Danach check auch unbedingt ob du über den RJ Stecker auch die korrekten Pins mit dem Modbussignal abgreifst. Schau dazu in die Doku des WR.
Auf der RS485 Platine müssen sowohl RX als auch TX aufblinken. Dazu must du mal alles (siehe dein Bild oben) aus dem Gehäuse herausholen.

[thakikka]

Ich habe das mir von Solax zugeschickte ZIP nochmal durchgeschaut und meine, dass hier dürfte die für meinen WR passende PDF sein:
Solax Power X3-MIC three phase inverter Modbus-RTU comms protocolV1.05 - public version.pdf

Ich weiss nun leider nicht, ob das ggf. eine Hilfe bei der Lösungsfindung sein könnte, aber zumindest konnte ich dem PDF entnehmen, dass die Baudrate wohl 9600 sein sollte. Im WR selbst konnte ich dazu keine Info/Einstellmöglichkeit finden.

Das habe ich zur der ModbusID finden können. Ich habe irgendwo den Tipp aufgeschnappt, dass ich in Verbindung mit dem Splitter, den ich verwenden muss, weil die Verbindung zu dem Stromzähler zwingend erforderlich bestehen bleiben muss, da ansonsten der WR direkt in einen Fehlermodus geht, die ModbusID im Gateway daher auf 02 stellen müsste.

Ausprobiert habe ich inzwischen aber sämtliche Varianten, also sowohl 01 als auch 02. Stets ohne Erfolg.

Hier zur Veranschaulichung ein Bild von dem Splitter:

Liegt da ggf. der Fehler? Muss ich da etwas gesondert beachten bzw. einstellen, dass die Verbindung endlich klappt?

Die Platine würde ich mir gerne (auch von unten) anschauen, aber noch war es mir nicht möglich, diese aus dem Gehäuse zu lösen. Zur Not muss ich das Gehäuse von unten vorsichtig aufschneiden oder so...

[tobiasfaust]

Ich weiß nicht wie der Splitter funktioniert.
Probier erstmal ohne Splitter direkt am WR. Egal ob der WR in einen fehlermodus geht oder nicht. Du musst eine Fehlerquelle erstmal ausschließen.

Hallo, versuche auch verzweifelt meinen X3 Gen1 anzubinden.
kannst du genauer erklären was du genau gemacht hast?
