Battery Min voltage shows 0v

Hello,

This is a system that I have at a cabin. Victron 100/20. With (2) 115ah batteries in parallel. I use the load out to control a couple of lights. And to disconnect, if the battery gets below 12.1v (about 50% battery life). Basically it pulls about (2ah). I had someone stop by and retrieve this data (below), to be sure the system is working correctly. To track consumption along with my yield. However i was supprised to see that the min battery voltage was 0v. I just dont think this is correct. How could this be 0v when the system seems to be working in all other areas. I have yield. I have consumption. I have a battery Max. But no battery min! If there was not consumption. And no battery Max. I could assume that i had blown a fuse. But that is not the case. Does any one have any explanation for the data below?

Check the fuse at the bottom of the MPPT.

0V battery everyday is mostly caused by a blown fuse.
