:rocket: Please describe your feature request

I have more possibilities regarding the control Logic if I can "see" the voltage of the battery and the voltage of the solar panels

:pencil2: Describe the solution you'd like

[x] adding the 3rd ADS1115 on PCB & KiKad Circuit Diagram
[x] simulation of calculated voltage divider
[x] Z-Diode is limiting the input voltage to protect the ADS1115 Input
[x] reverse polarity protection
[x] do calculation in code

:pushpin: Describe alternatives you've considered

A clear and concise description of any alternative solutions or features you've considered.

KiCad circuit diagram is updated and the circuit is soldered on the PCB. I only have to solder the Z-Diode which i have ordered.
