Sungrow WR SGH10RT erfolgreich mit MODBUS eingebunden

@gombersiob

Vollkommen richtig, so wie es im Screenshot ist, kann es nicht funktionieren - egal ob die Option "Multiple Device IDs" angehakt ist oder nicht. Mit der angehakten Option kommt eine zusätzliche Spalte "deviceId" dazu, die natürlich in der ersten Zeile entsprechend dabei sein muss.

Deshalb mein Verweis auf das github Repo, da passt es.

[Schneider]

Cool, hat geklappt. Danke für die Hilfe.

Jetzt habe ich die Objekte drin - allerdings stehen alle auf "0":

nicht wirklich.
Da steht bestimmt was im log.

Das NaN statt Registernummer spricht Bände

Wo befindest du dich da?

[Schneider]

Protokolle:

Objekte:

[Homoran]

@schneider ... und die Konfiguration?

[Schneider]

Diskrete Eingänge / Ausgänge habe ich nichts eingetragen. Ebenso ins Holding-Register.

[ubecker]

@schneider nimm mal in der Config Aliasse benutzen raus. Ich erinnere mich das hatte ich auch mal so

[Homoran]

@schneider bitte Logstufe auf debug umstellen.
Hak mal "aliases benutzen" ab

[Schneider]

Jetzt verbindet sich der Adapter nicht mehr

log bitte als Text in code-tags posten und auf debug umstellen

EDIT:
Wo komnt jetzt due Geräte ID 200 und doppelt so hohe Register her?

[berlinerbolle]

@schneider

Und nimm zur Sicherheit erstmal die Zeilen mit DeviceID 200 (das ist die für den Akku mit den entsprechenden Modbus Registern) ganz raus. Die DeviceID des Akkus MUSS nicht 200 sein (kann man zum Beispiel über das WinetS nachschauen), falls du überhaupt einen hast? Bin gerade am Handy und kann nicht zu deinem ersten Post schauen, welchen Wechselrichter und/oder Akku du hast.

Ältere Firmware Versionen führen den Akku auch gar nicht separat auf, das könnte auch eine Ursache sein auch falls du einen Akku hast.

[gmt94]

@schneider

Hast du im Winet dongel überhaupt modbus aktiviert?

[GombersIOB]

@schneider
Diese „Not-a-Number (NaN)“ beziehen sich auf die Registernummern. Da steht in der Spalte sicher noch ein Leerzeichen dabei. Etwa „4999 „ statt „4999“.

Das Thema hatten wir gerade erst

Deswegen warte ich auch noch auf das debug-log von @schneider

@gmt94 Ne.. Ich wüsste auch nicht wo. Ist mir zumindest nicht ins Auge gesprungen

[gmt94]

@schneider

Mal die IP Adresse vom wechselrichter im Browser eintippen und dann per admin anmelden. Passwort sollte in den Unterlagen stehen, dann unter System und weitergabekonfiguration Modus aktivieren.

[Schneider]

Das ist/war an:

Weiß jemand was das für ne Fehlermeldung im Log ist?

Mal ganz blöd gefragt, hat denn jemand erfolgreich einen WR vom gleichen Typ wie @Schneider ihn hat, eingebunden? Und falls ja, mit welchen Registern?

Die Fehlermeldung "Invalid FC 132" klingt für mich nach einer ungültigen Registeradresse.

Ich würde jetzt alle Register rausschmeißen, und nur ein einziges drin lassen - dann schauen ob es geht. Falls ja, nach und nach die gewünschten Register hinzufügen. Die Registeradressen sind zwischen den verschiedenen WR nicht unbedingt identisch. Es gibt da auch (unvollständige) Dokumentation von Sungrow dazu.
