DPL Stuck at 15.1% Power Regulation – Hoymiles HMS-1600 (Firmware V01.01.12) with OpenDTU On-Battery 2025.04.17

[DerGulli]

Geräte und Software:

• Wechselrichter: Hoymiles HMS-1600, Firmware: V01.01.12
• OpenDTU: On-Battery, Version 2025.04.17

Fehlerbeschreibung:
Wenn die DTU den DPL auf 15,1 % regelt, tritt folgendes Problem auf:

• Die DTU gibt dem Wechselrichter die Vorgabe, 242 W auszugeben.
• Der Wechselrichter regelt jedoch nur auf etwa 213 W.

Die DTU interpretiert dies als Verschattung des Moduls und erhöht das Leistungs-Limit nicht weiter, obwohl noch genügend Kapazität vorhanden wäre.
Dieses Verhalten konnte in den letzten drei Tagen mehrfach zuverlässig reproduziert werden. Der Umrichter regelt bei 15,1% immer zu niedrig ein.

So lässt sich das Problem nachstellen:

1. OpenDTU On-Battery (2025.04.17) mit HMS-1600 Wechselrichter (Firmware V01.01.12).
2. DPL auf 15,1 % setzen.
3. Den Sollwert der DTU beobachten (242 W).
4. Die tatsächliche Ausgangsleistung des Wechselrichters auslesen ( 213 W).
5. Prüfen, ob die DTU das Leistungs-Limit weiter anpasst oder auf der Annahme von Verschattung „hängen bleibt“.

Erwartetes Verhalten:
Der DPL sollte weiterhin versuchen, das Leistungs-Limit zu erhöhen, wenn die tatsächliche Ausgangsleistung des Wechselrichters deutlich unter dem Sollwert liegt. Die Abweichung zwischen Sollwert und tatsächlicher Ausgangsleistung ist bei 15,1 % zu groß. Die DTU sollte in diesem Fall nicht von einer Verschattung ausgehen, sondern versuchen, das Leistungs-Limit weiter zu erhöhen, um den Zielwert zu erreichen.

Ich habe hier schon mehrere Diskussionen darüber geshen. Ich glaube das bis 15% eine 20%ige Abweichung erlaubt ist und darüber nur noch 3%. Gehe ich etwas höher mit dem Limit regelt der Umrichter näher an das Soll.

Hallo @DerGulli

Hoymiles HMS-1600

Alles vier Eingaenge angeschlossen?
Ich gehe davon aus, die Hysterese ist auf ein Minimum eingestellt (um die Werte so nah wie moeglich zu aktualisieren)

Zieht jeder Eingang die gleiche Menge, oder gibt es Unterschiede?

ich kann kein solches Verhalten bei meinen HM1200 erkennen (nur 2,3W Unterschied)

Hallo, @Manos1966

ja es sind alle 4 Eingänge belegt, 2xOst 2xWest und alle hatten bis auf 1..2 Watt alle die gleiche Leistung.
Insgesammt waren sicherlich 800 Watt verfügbar.
Meine Hysteres steht auf 5 W.

Bei höheren Limitwerten regelt der Wechselrichter auch wie bei dir. Wie gesagt 16%-100% ok. Tiefere Werte trifft er nicht mehr so genau.

Kannst du mal deine Einstellungen vom DPL zeigen und ein log Auszug von dem Moment beistellen, wo er nicht regelt wie er soll?

Hi,
anbei ein Screenshot meiner DPL-Einstellungen.

Logauszug von gerade ( Leisung wäre sicherlich 800W da beim HM1600):

Gruß DerGulli

[DerGulli]

Heute hing der DPL erneut. Auffällig ist, dass dies immer bei 15,1 % geschieht. Fahre ich nun das Limit langsam händisch in 0,1 %-Schritten nach oben, regelt der Umrichter jeweils um ca. 1 W nach oben mit. Bei 15,3 oder 15,4 % springt der Inverter dann um 20 W nach oben, und der DPL beginnt wieder mit dem Regeln.

Logauszug von heute: ( Es geht um den HMS-1600 nicht um den HM600 dieser ist noch verschattet)

[AndreasBoehm]

Das hatten wir schon mal, keiner hats verstanden, schwer zu erklären. Das war nicht zielführend. Hab keine Lust mehr wieder unmengen an Support für die Einstellungsfindung zu leisten. Mein Anspruch ist es das OpenDTU-OnBattery selbst weiß was zu tun ist und wir User nicht dazu zwingen mega viel einstellen zu müssen.

[mastertape]

Ich betreibe DTU On Battery wegen dem DPL mittlerweile ohne Akku weil ich vom BKW Kleinakku auf nen Victron Multiplus mit 16 KWH diy Akku gewechselt bin - AC seitige Akku Lösungen kommen imer mehr - Vielleicht sollte man in Hinbleck dessen auch hier den DPL möglichst flexibel gestalten,, Die Kobi funzt eins a ausser Akku ist voll und sonne es ist zu wenig verbrauch... Vielleicht wäre da auch noch ne Regel anpassbar das fixe werte um 10% eingerichtet werden und bei bedarf der dpl automatisch das höher triggert..

Ansonsten muss man sagen das der DPL an sich auch mit mehreren WR seit dem letzten Updates wie schnüffchen läuft - danke für die tolle Arbeit!

[AndreasBoehm]

Was tut denn der DPL bei AC-Gekoppelten Akkus? Da sollte der WR doch auf 100% laufen um den Akku laden zu können und es bedarf keinerlei Regelung durch den DPL?

Meinen Solar WR lass ich auch permanent auf 100% laufen, Überschuss geht dann per Huawei in den Akku.

[spcqike]

Batterie betrieben WR sind da zum Glück eh aussen vor, die werden Stumpf mit einem Limit angefahren und wir gehen immer davon aus das die auch das liefern können. (Gibt natürlich vorher nen check ob die Batterie nen Discharge Current Limit gesetzt hat)

gilt das auch für diese smarten Akkus? die von sich aus auch weniger abgeben könnten?

Was tut denn der DPL bei AC-Gekoppelten Akkus? Da sollte der WR doch auf 100% laufen um den Akku laden zu können und es bedarf keinerlei Regelung durch den DPL?

so würde ich es auch machen, wenn Netz da ist.
Interessant wird der DPL mit AC Speichern erst, wenn man auf Ersatzstrom läuft und den Speicher aufladen möchte.
Da muss man selbst dafür sorgen, dass die Erzeugung gedrosselt wird, wenn der Akku voll wird.

Ich plane gedanklich auch bereits ein 3-phasiges Multiplus II Setup, werde mindestens einen Wechselrichter direkt am ESS Ausgang anschließen, sodass er auch bei Stromausfall Energie liefert, aber der muss dann entsprechend gedrosselt werden können. Was ich erstmal über einen Smartplug machen würde.

[AndreasBoehm]

Smarte Akkus werden wie 'dumme' Akkus behandelten, wir gehen davon aus das wir das bekommen was wir anfordern.

Hallo Andreas,

so langsam habe ich den Verdacht, dass es sich um einen Firmware-Bug in der Umrichter-Firmware V01.01.12 handelt.

In den letzten beiden Tagen (gestern und heute) traten keine „Hänger“ mehr bei 15,1 % auf. Allerdings zeigte sich nun ein anderes, für mich nicht erklärbares Regelverhalten auf Seiten des Wechselrichters – wodurch der DPL erneut betroffen war.
Die Regelung funktionierte den gesamten Tag über einwandfrei, bis der DPL die Leistungsbegrenzung von 14,4 % auf 13 % reduziert hat.
Hier die Regelhistorie:

Vorgabe %	Vorgabe Absolut	Istwert		Regelabweichung
13,50%	216	198		0,916666667
14,40%	230	203		0,882608696
13%	212	169		0,797169811
13,30%	212,8	169,4		0,796052632

Die Module sind nicht Verschattet, der Wechselrichter hält den Istwert stabil.

Gerade beim Schritt von 14,4 % auf 13 % ist der Leistungsabfall ungewöhnlich stark und durch die reine Änderung der Vorgabe nicht nachvollziehbar. Die Regelabweichung verschlechtert sich dabei über 20%. ( DPL hängt wieder und kommt erst wieder 45 Minuten später ans laufen nachdem nach unten herausgeregelt wird).

Nun stellt sich mir die Frage wie ich nun weitermache, vielleicht lässt sich das ganze durch vergrößern der "Hysterese" von 5 auf 10 Watt entschärfen.

Jedenfalls nochmals Danke für die Unterstützung und wertvollen Tipps. Ich werde weiter beobachten und berichten.

Gruß DerGulli

[DerGulli]

Hallo,
Ich wollte nochmals Rückmeldung geben.
Mein Setup läuft momentan auf Basis des Commits von @AndreasBoehm a307b9a und funktioniert damit weit besser als 2025.04.17.

Seitdem habe ich meine DTU/DPL mit den folgenden Einstellungen betrieben und beobachtet:

Insgesamt lief alles ziemlich gut, bis auf zwei Vorfälle, bei denen der DPL wieder in den Zustand „Verschattung“ fiel, obwohl eigentlich genügend Leistung zur Verfügung gestanden hätte.

Nun habe ich gesehen, dass die neue Version 2025.06.11 verfügbar ist, und würde diese gerne testen. In den Release Notes konnte ich allerdings keine Änderungen im Verhalten des DPL finden – zum Beispiel bezüglich einer Anpassung von „PowerLimiterOverscalingInverter“ oder einer Unterstützung der Firmware-Version 2.0.4 von Hoymiles.
Habe ich da vielleicht etwas übersehen?

Danke Gruß DerGulli

[AndreasBoehm]

einer Anpassung von „PowerLimiterOverscalingInverter“

Aufgrund deiner Rückmeldung vor ca einem Monat in der du erklär hast das du auch Probleme mit 13% und 14% limit hast hab ich meinen PR geschlossen und den commit weggeworfen, da die anpassung von 15% auf 16% dann wohl keinen wirklich unterschied bewirkt. Das eine Prozent macht dann wohl keinen Unterschied.

Unterstützung der Firmware-Version 2.0.4 von Hoymiles

Diesbezüglich gab es keinerlei Änderungen im Code, deshalb ist da auch nichts im release enthalten.

[DerGulli]

Hallo Andreas,

vielen Dank für deine Rückmeldung.
Vor der damaligen Anpassung hatte ich die Probleme täglich – nach der Änderung nur noch sporadisch.
Irgendwie komme ich trotzdem auf keinen grünen Zweig.

Ich habe mir das Repository mal geklont und werde die Firmware mit den damaligen Änderungen selbst kompilieren.

Vielen Dank und viele Grüße DerGulli
