What happened?

In release 2024.11.20 (latest), calcBatteryAllowance sometimes does not correctly apply battery limits, additionally it looks like start threshold (90%) and discharge even if partially full (off) were not applied as expected, since the battery was <90% the whole day:

To Reproduce Bug

Unclear, may be specific to my configuration? TBD.

Expected Behavior

  • Inverter should not flicker on/off rapidly
  • Inverter should not be enabled if battery < start threshold

Install Method

Pre-Compiled binary from GitHub releases

What git-hash/version of OpenDTU-OnBattery?

81b1e6e

What firmware variant (PIO Environment)?

generic_esp32s3_usb

Relevant log/trace output

No response

Anything else?

No response

Please confirm the following

  • I believe this issue is a bug that affects all users of OpenDTU-OnBattery, not something specific to my installation.
  • I have already searched for relevant existing issues and discussions before opening this report.
  • I have updated the title field above with a concise description.
  • I have double checked that my inverter does not contain a W in the model name (like HMS-xxxW) as they are not supported.

For the time being I've downgraded to 2024.10.20 (however until the other day I was running an older self-compiled version with custom patches).

Hallo @ranma,
ich arbeite gerade an einer ganz anderen Sache aber ich ich kann so ein Verhalten ebenfalls beobachten.

Es schaut so aus als ob die Inverter-AC Mess Daten nicht rechtzeitig bereit stehen. Beispiel:

  • Wir starten mit 81W AC

  • Ein neues Limit wird an die Inverter übertragen
    12:20:12.194 > [DPL inverter 112182846421]: sending limit of 18.3 % (55 W respectively), max output is 300 W

  • Die Regelung wartet bis die Inverter ok melden.
    12:20:12.254 > [DPL] waiting for a start/stop/restart/limit command to complete

  • Das Powermeter misst neue Werte.
    12:20:12.312 > [PowerMeterHttpJson] New total: 37.16
    12:20:13.278 > [PowerMeterHttpJson] New total: 60.00
    12:20:14.244 > [DPL inverter 112182846421]: actual limit is 18.3 % (55 W respectively), effective 2024 ms after update started, requested were 18.3 %
    Alles Ok. Ich kann erkennen das die Inverter das neue Limit umgesetzt haben.

  • Aber wenn ich jetzt über die Inverter Stats die aktuelle Inverter AC Leistung einlese. (über getCurrentOutputAcWatts() )
    Dann bekomme ich 78W zurück und nicht wie erwartet 55W.

Die weitere Regelung verwendet aber die 78W und kommt damit ins Schwingen.

Bei mir schaltet der Inverter mit der 2024.11.20 auch zu früh wieder an: Habe den DPL eingestellt dass er bei 80% SoC starten soll und bei 45% stoppt. voltage_start_threshold und stop ist deaktiviert.

Aber er schaltet den Inverter schon 53% Ladung ein... und das eigentlich immer!

Genau so hatte ich ein merkwürdiges Phänomen festgestellt, dass er sich gar nicht anschaltet, wenn ich nicht manuell in der Konfig die ich exportiere den Wert von solar_passthrough_enabled auf false setze und wieder hochlade.

Das hatte ich hier schon geschrieben: #1471

Das sind die powerlimiter-Werte aus dem Konfig Dump:

Alles Ok. Ich kann erkennen das die Inverter das neue Limit umgesetzt haben.

Diese Info sollte die OpenDTU mit SystemConfigPara eingesammelt haben.

Jetzt müsste für alle Inverter ein RealTimeRunDebug laufen damit ihr auch die aktuellen Inverter Werte in de OpenDTU habt.

  • Aber wenn ich jetzt über die Inverter Stats die aktuelle Inverter AC Leistung einlese. (über getCurrentOutputAcWatts() )
    Dann bekomme ich 78W zurück und nicht wie erwartet 55W.

Die weitere Regelung verwendet aber die 78W und kommt damit ins Schwingen.

Hier hat wohl der DPL loop die beiden o.g. Kommandos überholt und regelt bevor der neu akzeptierte Regelpunkt angefahren wurde.

Dies hängt evtl. natürlich auch vom Delta und dem RampUp/RampDown Werten im GridProfile ab.

Das eigentliche Problem ist ja das der Inverter gar nicht an sein sollte. Solarleistung ist zu klein und Batterie-Ladestand ist zu niedrig => Inverter sollte aus bleiben. Trotzdem sehe ich in 2024.11.20 das eher morgens/abends mal gerne mit bis zu 800W ins Netz speist, auch wenn er nicht sollte.

Mit 2024.10.20 funktioniert das so wie es soll.

Ja, sorry. Ich dachte Anfangs die beiden Probleme hängen zusammen. Aber da habe ich mich getäuscht.

@stefan123t

Richtig, aber in meinem Fall ist das nicht das Problem. Ich sehe ja an den Powermeter Messdaten das der Inverter das neue Limit eingestellt hat. Nur die Messdaten vom Inverter sind noch nicht auf aktuellen Stand.
Ich habe jetzt das Inverter Poll Intervall von 4 Sek auf 2 Sek reduziert.
grafik
Das scheint auf den ersten Blick besser zu laufen.
Ich beobachte das mal eine Weile und wenn mir noch was negatives auffällt dann mach ich ein neues Issue auf.

Also bei mir ist der Poll Intervall des Stromzählers schon auf eine Sekunde.
Hilft es wenn ich ein Log bereitstelle und wenn ja, was muss aktiviert sein (ausführliche Protokollierung von welchen Funktionen), damit alles enthalten ist, was nötig ist?

@ranma @ThomasCr Könntet ihr nochmal mit einem build des aktuellen development branches testen? Es hat sich nochmal einiges getan im DPL code seit dem letzten release.

Builds findet ihr hier: https://github.com/hoylabs/OpenDTU-OnBattery/actions/runs/12599153511
