Hi BradWiring diagram looks good!
Just one thought on the volt indicator unit....
If you are using this to display the status of the main battery bank, then it may not work as intended.
Since you are measuring 12v from the step-down inverter, it will always show 12v, even with your bank highly depleted.
Think of it like this...
I can only lift 200 pounds flat out. I would consider myself tired if I could only lift 150 pounds.
But give me a 4x lever (48v to 12v), and even tired, I could still lift 600 pounds.
See where I am going with that?
Your full bank should show almost 51 volts when healthy, but the 12v side will easily show full output even fed with 40 volts (completely dead bank).

I sorta thought about this, before purchasing the 5-gang switch panel. I understood that the panel I wanted came with the 12v-24v voltmeter, so knew it wouldn't work for the 48 volt system. And there may be a possibility it may not be used.
My thinking was; I need a volt/capacity meter, in addition to the one on the battery pack.
Reason being, the one on the pack won't be seen, once I get the console cover installed.
Though I suppose I could, remove it from it's present location, and install it, up on the console....hmmmmm. I'll have to think about that.
Anyway, I bought the linked voltmeter, to do that.

The voltmeter, on the 5-gang switch panel, only meters 12v-24v. Now this may be where my logic, won't work. The output for the dc-dc converter, brings the voltage down to +/- 12v, so the switch panel voltmeter, would show what voltage, that is coming out of the converter.
Based on your statement, maybe not ????? This is a dc-dc converter, which is supposed to convert 48 volts, down to 12 volts. This being the case, then I gather, there is no true way to measure/monitor the 'output', of the converter.Since you are measuring 12v from the step-down inverter, it will always show 12v, even with your bank highly depleted.
Am I supposed to take it, that the converter is actually working correctly, and just putting out the correct 12 volts? How do I check to see if it is working correctly?
If not, then I'm only out a few dollars, and I will probably remove the voltmeter, in the switch panel, and use that space for the key ignition.
Thanks for jumper-ing in...(no pun intended)...well maybe.
