ACR

Hi all,

Has anyone any suggestions for wiring a twin engine boat with three house batteries so five batteries in total. I like the look of the blue sea automatic charge relay complete with battery insolation. However, I cannot find a solution for using this ACR with two engine batteries along with the house batteries. Ideally, I would like to be able to charge either engine battery along with the house batteries using the one blue sea ACR. Is this possible? If not, any suggestions welcome. My own thoughts if this is not possible is to wire one engine battery to the blue sea ACR along with the house batteries and keep the other battery separate but be able to use the emergency start button to transfer power between engine batteries if I get stuck.

P.s forgot to mention it will be two isuzu diesel engines, both with voltage sensing regulators on alternators.

Thanks in advance,
Tony

An ACR, like the blue sea Si series, is going to service 2 banks.

Sounds like you are looking for something like the Promariner ProIso. Looks like they offer a 2-in and 4 out.

Thanks Wylie.will look at that one.

View attachment 85985 While not a SR, here’s what I just did on my Meridian. May be of some help. Meridians came with twin BEP Voltage Sensing Relays.....that connect, or disconnect all three banks. Port, house, stbd. My relays were not functioning properly so I replaced them with dual Blue Sea ML-ACRs. They each come with their own connect/disconnect remote switch, as well as a manual toggle on the unit itself. It will automatically direct charging where it needs to go, and isolate banks if need be.

thank you for your reply.
Will look into that option.im planning on supplementing house batteries with solar charger too.will that work ok with the two acr .
Thanks in advance
