Log,
I'm glad your system works well for your needs.
It takes a great deal of time for a battery bank to become full. At 85% state of charge, the acceptance rate is a mere 15 amps per 100 amp hours of capacity. The closer the battery bank is to full the slower the charging rate.
Sulphated batteries behave by showing they are fully charged by voltage, shortly after being connected to a charger.
Most "smart" chargers fail to drive a battery 100% state of charge. Getting to truly 100% requires "dancing on the needles", especially if voltage is the only parameter being used.
You have really gone beyond the need for a DC to DC battery charger.
