Hunter 450 house bank wiring question

[AKlight]

I've looking at the schematics and inspected my current configuration on my '99 450. Everything I describe was how it was when I purchased it 3 years ago. I assume it is how it came from the factory.

Trying to figure out how I'd go about adding solar.

1) Battery negative wiring - 4/0 from battery A neg term to battery B term. A long 4/0 runs from battery B negative to a busbar under the port settee.
2) Both battery A and battery B have a 2/0 wire running to the battery switch over on the face of the port settee. They do not seem to wire to a busbar but instead to the 1/both/2/off battery switch.

So how do people go about attaching their charge controller? are folks changing this wiring and adding a pos bus bar somewhere and swapping the battery switch?

Thanks!

Is one bank a starting bank and the other a house bank?

Do you have to manually switch to all once the engine is started or are both banks charged automatically?

Do you have an inverter/ charger or a seperate AC charger? How is your alternator wired to the batteries? Do you have wind or any other energy source?

We'd need a deeper dive i to your electrical system.... as it's on the boat, not necessarily assuming that what was wired at the factory is still present.

Generally speaking, you would want a hot or always on bus for bilge pumps and charging loads. Then the battery switch, then all your other loads. An easy way to do this is with a victron Lynx distributor (add bolts and fuses) or Lynx Power In. From the Lynx, you can branch off to the ac charger (inverter?), alternator input, solar bus bar (if you have more than one mppt) and then to the house switch.

Spend a few days watching these videos are reviewing their articles and you'll have a good feel for how it should be done.
