Need help with what needs to be bought for whole system

[-cycosis-]

Goal: simple-ish electrical system.

12V system to power the following:

-Fan for my dickenson marine heater
-LED lighting (6 maybe?)
-3 way fridge (just the display, cooling via propane)
-SeeLevel fresh, grey, black tank monitor
-Water Pump
-Water heater ignition (heat from propane)
-2 roof mounted vents

120V system to power the following:

-13500 BTU rooftop A/C
-4 outlets (laptop, phone charging, blender)

12V power source, 1 or 2 deep cycle batteries

120V power source: 3300 watt inverter generator connected from a single 30 AMP outlet outside the bus

SO what components do I need to buy?????

Have you insulated yet?

spray foamed but thats it. just finished ripping up, treating and painting the floor so conduit is more or less the next stage

I didn't know what stage of your build you are at. I don't enjoy doing floors much. Are you planning to strip out the interior panels and insulate?

I felt like I was getting in deep on my first floor demolition. The wood was so rotted that the rusty screws could puncture your shoe. Big fun.

We used a Marinco 30 amp twist lock shore power inlet connected to a Progressive Dynamics 4045 Power Center. The power center has AC breakers, DC fuses and an AC to DC converter with a 3 stage 45 amp battery charger for the two 6v deep cycle batteries (connected in series to give 12 volts). Used 10 ga. stranded cable between the marinco inlet and the progressive power panel, 12 ga. armored cable to the AC dulpex outlets and 14 ga. stranded primary wire to the DC lights and outlets.

If you want wall switches for your lights get DC rated switches such as these:

Switch Assemblies for RV, Trailer, and 5th Wheels

Assuming you have a steel bodied bus, be sure to ground the power panel to the bus body to avoid the dreaded "hot skin" condition.

^This is very helpful! So i can connect my rooftop A/C to this thing as well as all my 12V fans/lights? AAnd it will charge my batteries?? Sounds like a win win win

Yep. AC and DC plus a battery charger in one small package. Those Progressive Dynamics panels are just the thing for RVs and buses.
