Connecting Argofet Isolator to Paralleled Battery Bank

When connecting an Argofet Isolator to a battery bank with paralleled batteries, do you use one isolator output for the entire paralleled bank, or use multiple outputs, one for each battery In the paralleled bank? On my boat, I have a starter bank with a single group 34 battery, and a house bank with two identical group 31 batteries. I’m believe I need a two bank isolator but just wanted to confirm that I don’t need a 3 bank isolator. Thanks for your help.

I spoke to a Victron distributor and he confirmed that the paralleled batteries should be treated as a single bank and only receive one output from the isolator. So in my case I need a two output isolator, with one output for the starter bank, and one output for the house bank.

Yes - one output per battery bank.
