Deine Batterie ist zu klein. Der wechselrichter kann aus 24V keine 2.000W ziehen. Das wären knapp 21A pro MPPT. Er begrenzt bei …. 15?16? Irgendwie so. |

Hallo,
ich habe am Wochenende meinen alten Wechselrichter gegen einen HMS200 4T und Opendtu on Battery ersetzt.
Soweit läuft alles jetzt ganz gut. Ich habe nur das Problem, dass der Wechselrichter nicht auf 2000 W hochgeregelt wird.
Wenn z.B. vom Haus 2,5 kw bezogen werden steuert die DTU nur auf knapp 1500W obwohl in den Einstellungen als Maximale Leistung 1900 eingetragen sind. Von der Batterie Spannung liege ich dabei auch noch weit weg vom Abschaltpunkt.
Kann das ein Einstellfehler an der DTU sein oder evtl vom Wechselrichter kommen?
Hier mal ein Auszug aus dem Log.
