Re: Battery Switch Setup

No, you should have the inverter fed from the house bank. Diodes cause voltage drop and are way old technology.

For other wiring see these:

This is another very good basic primer for boat system wiring: The 1-2-B Switch by Maine Sail (brings together a lot of what this subject is all about)

Re: Battery Switch Setup

The diodes, and the second switch, have me scratching my head... What are you trying to do? Why do you have DC running to an AC panel?

Assuming that you have a 1-both-2-off switch, you should only need one switch.

Many marine inverters, are actually Inverter/Chargers, and would come with more complete instructions than you will get here. Here is an example;

However, if you are hard-wiring an inverter, it should normally be connected to a breaker on the DC panel, labeled "inverter." The DC breaker panel would be energized when you select power from the 1-both-2 switch. You must have some form of circuit overload protection for the inverter circuit.

You may want to learn more about them by reading this;
