Blue Sea has their brand chargers that can be connected to the ACRs and will do the switching off of the ACRs automatically. Problem is that they don't make a charger larger than 40 amps last time I checked.
Thanks. One reason I like either the Duo Charge or Echo Charge. They don't combine the banks at all but send a small amount of the charge current to the start battery. The house bank gets the bulk of the charging current and the charger never "sees" the starting battery.
