Inverter Disconnect (Lengthy)
I'm in the process of installing an inverter disconnect relay. This will cut off the feed from the battery--not the 120 volt output to devices/appliances. Here is my hypothesis if you want to call ...

I think I got this nipped in the bud.
First of all I want to thank all who contributed their efforts to come up with answers. I took notice for comments made by Piano T. Your set up replicates the concept that prompted me to take on this project.
Although it differs a little bit from my system criteria, they are identical nevertheless.
This system, along with my Tri Metric, has a warning system that I added on.
It monitors the battery voltage just like my TriMetric. When the battery voltage sags to around 12.3 volt (approx) a piezo (high tone) audible signal warns me that I have two minutes (thereabouts) to make corrective action or the system will shut down.
The system works perfectly on the bench by simulating the scenario mentioned. It is kind of touchy because the "precise" voltage that it senses before entering the low voltage threshold varies. Temperature rise in the compartment could affect performance of the ICs that trigger a gate to trigger the piezo. So false alarm is a possibility.
This is one that motivates me to take on this project.
Now, going back to how I got this nipped in the bud.
After almost throwing in the towel, I figured I'll give it another shot. I dismantled the whole thing and even went back to the drawing board so to speak.
I assembled this gizmo with wire harnesses that allows me to easily separate each section (three component enclosures) with molex connectors. What I found in the molex was one barrel (female pin) that mates with the male pin got pushed in not allowing the two to mate together. It was momentarily making contact when I wiggle the harness, which explains the intermittent operation.
As to why it blew the fuse, I would take the hint from Piano T in going to a heavier fuse.
So,thanks a million to everyone for your comments.
Now I can really call myself a Happy Camper.
