Fully charged lead acid batteries should show 13.2
volts. If they are chaarging, then they should be
higher than that, typically 14.7 in a running
automobile.
A battery bank that reads 12.0 volts has not been
charged recently.
Sounds like there is a short somewhere in the house
bank line that is sucking up 60 amps of charging
current without giving it to the batteries. At least
that's one possibility.
Measure the house bank voltage when it is drawing 60
amps -- it should go up from 12v.
On the other hand, maybe a big house bank that badly
needs charging would pull 60 amps from a charger
capable of producing that. All depends on the exact
equipment you have.
Maybe try connecting one battery at a time to the
system and see how it reacts. Somehow you need to
isolate where the problem is by disconnecting various
loads and watching the ammeter.
Any more details would be helpful.
