It looks like Will had updated the diagram showing the fuse on the battery.
The MPP has the circuit breaker for the AC input, it is located on the bottom left of the unit.
For AC output, it should have circuit breaker as well.

MPP and a few other manufacturers now sell a "complete off grid system in a box" that has: AC Inverter Solar Charge Controller AC Battery Charger Automatic Transfer Switch (if grid power is...

On one of my older system build videos I said you can get away without a fuse on the battleborns. But all of the schematics and all of the recommendations have had a fuse of some sorts on them.

And in the book it states every conductor needs to have over current protection device

I'm here are rewatching your "beginners 48v" video from 2019 trying to figure out to turn of that incessant beeping...
I am using a Powmr (from before they even had a name, there is no name/logo/anything on my Allinone. It's a 3500watt 110. (I kinda regret not getting the 5000watt 220,but I've barely needed 220v anyways).

My issue is finding a manual or simply what setting will stop the that infernal beeping. (Specifically at sunrise and sunset as it bounces between enough charge and not enough from the PV)

Anyways...if there is any way you can help, I'd greatly appreciate.

Scroll through the set up menus and find one that resembles this:

It won't necessarily be option 18 on your particular inverter but look for that code.

You might also have one like this:

To get to the options menu and make setting changes:

These are all the setting that I am uncertain of and have never changed. All other settings I know what they are. It's possible I'm stuck with the beep. I'm just in a place where the last two hours of sunlight are shaded by trees and it's two hours of constant on/off PV beeping. ? I really hope it's one of these.

I doubt it.

01 UTI
Output source priority. Some inverters also have an SUb option as well:

03 UPS
Voltage input operating range. Your voltages may vary, this is just to describe the function: Also changes how quickly the UPS function cuts over from utility to battery. UPS mode is quicker but also tend to modify the waveform more as a result.
