Read remaining voltage on bluetti

I want to connect my AC200P to an automatic transfer switch, to do that I need to be able to read the battery voltage on the AC200p in order to set the switchover value. Are there any ports that the bluetti would give an accurate reading. I’ve tried the 12v/10a and while it will go up, once it hits 13.2v it stays there regardless of remaning battery.

Hi @kiab115 , Very sorry, at present the machine only supports manual transfer switching.
