Bonjour Johan, est il possible si j'en prend deux, d'afficher le premier par exemple dans Entrée CA et le deuxième dans Charges CA sur le VRM Portal, car j'ai un onduleur de type Voltronic dont les valeurs sont vraiment pas fiable, et ainsi avoir toutes les données sur le VRM Portal grâce à mon Cerbo GX.

Strange choices for the design. The small 1.5mm2 conections for the voltage measurements are a pain because one can never make safe cables on high amps circuits. All 4 wires need additional fuses in my opinion. Als RJ connections on the top is very hard to install nice and clean. The fidling with the small and vulnerable ct clamps between thick wires creates faulty installations.

Great device, lets hope Victron creates also residential 3fase invertors in the near future and add more compatibility with high voltage batteries.
Could be 😊
Yes, support for 400-800V batteries is a great addition!
A 3 phases inverter would be a must have....
Should have added RJ45 connection on the top and/or bottom, ao you can run the cable inside the DIN-rail enclosure..
