Hallo zusammen, auch auf die Gefahr hin dass ich einen Rüffel für ein Doppelposting bekomme weil ich die Frage an ander Stelle bereits in ähnlicher Form gestellt habe, aber das Thema wurmt mich und ich komme irgendwie nicht weiter.
Irgendwie werden sämtliche Einstellungen die ich in der utils.py vorgenommen habe völlig ignoriert oder ich hab einfach noch etwas übersehen.
Das System besteht aus einem MP2 3000, einem MPPT150/45 sowie einem 16S 105Ah DIY Akku der mit einem JK BMS ausgerüstet ist. Ein Initalladen und TOP Balancing habe ich vor einiger Zeit schon durchgeführt. Der MPPT lädt (aktuell im Testbetrieb mit einem Labornetzteil) wie er soll. Aber ich bekomme aus irgendwelchen Gründen weder CVL auf meinen gewünschten Wert, noch kann ich den max. Entladestrom auf die gewünschten 75A erhöhen.
Anbei meine utils.py eventuell kann mir jemand auf die Sprünge helfen warum meine Änderungen in der utils.py vom VenusOS ignoriert werden?
