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.

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.
