Cerbo GX Mk II questions

New marine install.
2 x 100 aH Renogy lithiums
Renogy MPPT (bought before this renovation, wish it was Victron)
2 x Renogy 100w solar panels
VE.Can Shunt
Cerbo GX MkII
GX50
Phoenix Smart Inverter 1200
This is a dedicated power supply for a 12v A/C, a 12v water heater, a 12v refrigerator, and a Starlink mini.
Question 1:
I would like to configure the inverter as AC1 with Shore Power as AC2. I have a BlueSea transfer switch that controls power to the AC panel. I can’t change the generator label but is there any reason this won’t work? I am adding a Smart Shunt to the Start and House batteries to be able to see them.
Question 2:
I would like to monitor my two fuel tanks which have analog tank senders. Do I just run a wire pair for the tank senders to the Cerbo GX. They don’t go anywhere now but I have checked them with a multimeter and they do have a variable output.
Thanks!

Question 2.
You need to find out what type of output signal your senders have and what outputs when empty and full. Resistive senders can be connected to the Cerbo mkII. Voltage (max 10V signal) or 4-20mA current sensors need to be connected via a GX Tank 140.
