Yes, that is sort of correct.

A new inverter may not have had the ability to pair with a second shunt. The first is in your house battery bay, btw. So the small wires were no longer needed.

However, I do not understand why the large ground cable is not connected. To provide more insight, you may have to physically trace the taped wire to its other end.

Yea, it goes under the panel there really quickly.  I will try to see if I can get some visibility under there or if I pull on it a bit it might wiggle in the battery compartment.
