Battery minimum voltage of 0.00v would indicate a blown fuse/breaker between the mppt and battery.

If fitted check the fuse in the underside of the mppt.

Your model mppt does not have a fuse.

You have found the cause of your blown battery fuse though.

Time for a tidy up.

It will have an automotive type ATO fuse in it.

A 30 or 35 amp fuse would suit.

It should have an ATO fuse in it, your pic is blurry. This ia an automotive fuse fitted to cars and trucks since 1970's, and will be easy to find in any auto store, servo, gas station etc...

When the fuse blows, the wire link in the middle breaks.

Yes! It is that thing!

And I believe it can be replaced with any automotive fuse with the right size (there are two types with different width) and amperage.
