Yes an ACR is an 'Automatic Charge Relay', which is really a VSR or 'Voltage
Sensitive Relay'. Connected between the positives of the two batteries (or
banks of batteries), it is an automatic switch that closes and combines the
batteries together when it senses a charging voltage on one of them, in
order to charge the 2nd battery bank, and opens to disconnect the two
batteries when the voltage drops (indicating charging has finished or
discharge is occurring), so that the 2nd battery is not discharged as well.
They also will not connect to a severely discharged battery or when an over
voltage is sensed (battery or charger failure). And they disconnect during
starting. Other companies make similar products, such as Yandina or
Magnacharge. Also, it should be noted that these types of devices are much
better than the older-style diode-based battery isolators, which because of
the voltage drop associated with diodes don't efficiently charge the 2nd
battery.
We've had quite a discussion going on these types of devices recently, under
the various iterations of this wiring thread.

Automatic Charging Relay.
If I am not mistaken it is a Blue Sea answer to the Echo Charger.

no such thing as a dumb question. We all learning all the time, some of us
know more on a subject than others and I am sure those in the know will
help....

Hi Edd, I love your diagramme and
will be lurking on this list to get answers of my own. 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. Regards, Alexander M.
