Bus electical system ac/dc how to????

[someguy]

So i got an idea but just need someone to say yes that is right or no do this.
So I got a 45 amp converter not sure on my inverter yet thinking to do a 2500 watt? not sure. then just going to run a 12 volt battery changing system?
Ok so from the bus Batt. I'm going to have a switch from that it will run to the house batt. then the inverter is hook to that, then run a wire from the inverter to the converter which will run to all the plugs and appliances the converter will also have shore power hook up. Solar power is also going in and that ties into the house batt.

So pretty much in the bus is going to be Refrigerator gas and electric, water heater gas and electric, washer/dryer combo, and A/C? these will be the big electric items..
