Thanks for your suggestion, i've used another SW, MultisibControl, and i'm able to see SOC for both batteries, see the image in attachment.
In batteryView instead I can't get SOC information even if I set the comunication like you suggested.
So now the question is if the batteries are fine and the problem is on the inverter side, what do you think?
Now batteries works well till i connect inverter to the internet, when i do so, the inverter put the batteries in off mode....very strange issue..
