The charger is connected to the ACR's disable lead so the charger can turn it off. When the charger is active, it disables the ACR so that it can manage the charge profiles of each bank independently. That is, go to absorb one one bank while floating the other one. When the charger is off, the ACR works as usual, combining the batteries when a charging source such as the engine alternator
is available and separating the batteries when no charging source is operating. Good stuff!
If you install the ACR without the blue seas on/off/combine switch don't you lose functionality???
Also in your set-up when the charger is just trickle charging, will the ACR combine or separate?
Final question, since your set-up opens the ACR during charging -- if a major load like the cooler is on it will use a high percentage of the possible charging current
from one leg of the charger while the other is on trickle/float. Somehow that sounds like bad mojo. Could you help me understand?
Not looking to start anything just learn from the smart guys in the room.
