Sounds like a strange setup, can you please make a simple wiring diagram?

What capacity do the batteries have?
Mixing 6V and 12V batteries with different capacities together is not recommended.

Bonjour

as matthias said, it's not recomended to mix this !


vous avez de la documentation sur le câblage en français ici:https://www.victronenergy.fr/upload/documents/Wiring-Unlimited-FR.pdf


vous pouvez également lire notre documentation energy sans limite: https://www.victronenergy.fr/upload/documents/Book-%C3%89nergie-sans-limites-FR.pdf

une configuration comme la votre ne peut être viable dans le temps et nous ne pouvons donc vous conseiller sur un tel câblage.

bonsoir.

Non, l'ensemble des batteries ne se marient pas. Quelle type de batterie? OPZS? Plaque épaisse?

Une méthode du pauvre serait de mettre les 2 - 12V-120Ah- en parallèle et de rajouter en série les 2 6V 230AH pour approcher des capacités équivalentes. Il ne faudra pas mettre de mesure de tension intermédiaire qui sera fausse. On oublie la mini 12v 90Ah-

Avec un peu de moyen, on change TOUT.
