ACR=Automatic Charge Relay For Blue Sea components, it is an relay that is wired between two batteries (or banks) and is normally open. When one of the banks is at a charging voltage (something over 13v, IIRC, which indicates that a charging source is present) and the other battery is partially depleted (under something like 12.2 or 12.3, IIRC) the relay closes and lets current flow from the high voltage source bank to the low voltage bank. If the batteries are both in the 12v range, the ACR stays open. If one of the batteries is really low, which would indicate a bad battery or a short or cause high current flow, the ACR will not close.
Unlike an Echo Charger, current flow is determined by voltage differential and not limited by the ACR. Also unlike an Echo Charger, the current will flow either way from high to low - an Echo Charger is a one way device.

Mine is a bit simpler than yours, but I plan to re-wire my AC/DC stuff after having my electric motor put in and will be re-wiring everything to replace the old companionway panel with a Nav station panel and cockpit sub panel and all the old wires with new tinned ones. So, I will compose my questions to you first, then later when back from the boat. My boat will, out of space etc and personal leanings be a bit less ambitious than yours, but am intrigued with all the devices. So, if you don’t mind a pile of dumb questions, let me fire away.
