First, thank you very much also from me for sharing your project. As you see, it is very interesting for so many people.
I am also thinking about replacing the batteries to lithium and would go your way.
About the electric cables, I saw that you need 2x 50 mm2 (2x plus and 2x minus). I think that both exist already. One pair for my 2500W inverter and one for the 100A Dolphin charger. They both 50mm2 (or more). The cables for the 30A are 40mm2.
- did you install the Skylla-i 80 amp just as a backup? would the 2x 40mm2 of the Dolphin 30A be enough?
- what did I not understand correct with the electric cables?
