When you also get your battery monitor such as a Trimetric it will have its 500a shunt for your negatives.
Now the battery to frame ground wire is disconnected from the battery and goes to the side of the shunt that has all the other neg wires, and one fat wire goes from the other end of the shunt to the battery.
That still has the battery neg grounded to the frame, but you get the info to the monitor by having the frame amps through the shunt.
With the inverter, converter, solar controller, and frame ground, all to the shunt, it will stack too many lug terminals under the shunt's bolt. So use a neg buss to collect the various neg inputs and then a fat wire to the shunt from the buss.
