Connecting a smartshunt to a peak power pack 40ah

hi there,
is it possible to connect a smartshunt to a peak power pack?
the system is now:
an orion 12-12 for the car
a smart ip 22 charger to charge the PPP when connected to wall-power on a camping site
the battery is a ppp 40ah on what I can see a mover is connected, on the car/solar is the car connected (or mobile solarpanels to charge while driving or offrid the panels)
a smartdongle for easy use of the battery withe app instead of the button.
And ofcourse on the domestic connected to the lights and stuff.

What i want is to see how much power there is left in the battery and to see if my solarpanels are charging the battery.
My easy thinking brain tells me that i can do it with a smartshunt but I have no idea if thats even possible on a peakpowerpack. And how to connect it.
Thank you already.
