Installing an ACR with a Freedom inverter/charger

I am rewiring my battery distribution panel to include an ACR. I also have a Freedom 20 inverter/charger with an eco charger for the starting battery. My question is have I got the wiring correct or will the ACR and eco charger interfere with their respective performance? I’ve included a wiring diagram for the battery banks.
Blue sea suggests a NC relay on the ACR ground to disconnect when plugged into shore power but this seems to be for cases where the batteries are different. Our batteries are all the same chemistry.

You don't need an acr, you already have one in the ec.

Because it is a Link 2000, I have one, the house bank must be #1, and the F11 function should be reset from the default on to OFF.

If you haven't yet, you should also read these:

DEFAULTS are factory settings that are made to be modified to suit your setup.

I was thinking the same thing except I would have said that he doesn't need the EC with an ACR! What would be the reason for choosing one over the other? I suppose that it would depend on what you already have. I have an echo charger and was making plans to eliminate it this winter in favor of installing an ACR. :huh:

The OP already has an echo charger built into his Freedom I/C.

An ec is all that's needed to keep up a start or reserve bank. Maine Sail did the heavy lifting on the myths in this:

An ACR is completely unnecessary if you already have an ec on a sailboat.

Love your wiring diagram. Could you send a PDF copy? Thanks.
