Best solution for Dual House Bank

I have followed Maine Sail's thinking for quite a while, as I refit my 1983 CaboRico 38. I'm now at the Electrical portion of the re-fit, setting up a separate Engine cranking battery and 4 Trojan T1275.
Unfortunately, I have to separate the House Banks with 2 under the Quarter Berth and 2 in the Cockpit Lazerette with the Cranking battery. All batteries oriented for and aft for minimal leakage and plate coverage.
Engine is connected to a on-off switch with a bank 1 parallel switch, which can completely isolate the cranking battery if needed.
Both banks feed the Electric Panel, which has an Off-1-All-2 130AMP switch as part of the panel, planning on leaving to All unless need isolation of either bank.
120vt Battery charger to Bank 1 and 2 and an Echo charger from bank1 to the Cranking Battery.
FourWinds II connected to Bank 1 and 2.

Need advice on connecting the Alternator to the House Banks and hoping for parallel charging as one bank and connecting the Inverter and Windlass as one bank.

Any thoughts? Will consider another switch or solenoid.

Drawing attached with the Alt, Invert, and Windlass not wired yet.

Thanks in advance

You'd be best to contiguously wire the house bank keeping the parallel, jumpers between the aft pair and forward pair the same length. You will need a fuse at each end of the long parallel positive jumper. Take your positive off the aft pair (or forward) and the negative of the opposite end of the bank and use large cable 2/0 or larger..

Did you mean "oriented port to starboard" for minimal leakage?

Re: Best solution for Dual House Bank

Yes, the batteries are mounted Port and Starboard, allowing the cells to be fore and aft like your setups, i hope.

I'm not following your recommendation, will I need to re-wire the system or just add a new larger gauge wire to complete the parallel circuit for the Alternator?

How far off am I according to my diagram, which i added a solenoid and Positive Buss bar.
I considered a Solenoid running off the Ignition switch, but if one bank goes down I cannot isolate if needed. thought another off-1-all-2 may be required.

Re: Best solution for Dual House Bank

Let me rephrase "I'm not following your recommendation," I didn't understand the recommendation. My fore and aft cables are the same size on each bank, but how should l parallel the port and starboard bank to utilize the Alternator to charge both banks as a single bank, and pull the power for the Windlass and Inverter as one bank?

Replace the words "port" & Starboard" with fore & aft....

Re: Best solution for Dual House Bank

I love Pictures, thanks you...

Would it be OK to install a Buss Bar to the Positive Take off and connect the Windlass and Inverter, along with the alternator?

If the OP wires this way he now has a 24V system given the batteries he indicated.

A few questions for the OP:

Are you using all old parts or are you doing a complete refit of the wiring?

Why a separate charger inverter?

Are you going to use an ACR?

Are you intending to put in a battery monitor?

These systems get complex. I would start with a logical model first and then think of the physical implementation after and then plan for all the terminal, hardware, fuses and cable runs after.

Absolutely a good idea.. Fuse still goes before busbar though..

Looks to me like there are two 6V banks in series that are then connected in parallel. Would be 12 V.
