I would like to track the state of charge of my Peak Power Pack, something which is sorely lacking (for the price I kind of expected something like this to be included, actually!). The difficulty is the different current paths, I have the charger connected, the car/solar connector is also connected, and of course the load is connected to the "mover" output. Can I tie all the "minus" connections together (charger, car/solar, load, and possibly even ve.direct ground), connect this to a smartshunt, and then connect the smartshunt to the PPP? In other words: the minus of the charger adapter, the car and the load are connected to the load side of the shunt, and the other side of the shunt is connected to the mover output minus of the PPP.
