I am assuming that my battery is good now so it is mostly in float or bulk mode.

There are many similar questions in the community, please use the search function.

You have 0V battery voltage everyday that is a sign that there is a problem with the connection between the MPPT and the battery.

Check all connection, switches and fuses between the MPPT and the battery.
