45 amp or 60 amp? is this a fairly easy option for later install of solar?
can the unit be located under the front bunk in the storage area or is it easier to just remove the old breaker box and install its location?
looking at the diagram, i need to run lines directly from the battery to the new power center - do i just cut and cap existing battery lines as soon as they come into the inside where the black and white connect immediately to the rainbow and run new dedicated lines to the power center? How would the new system tie into the rainbow wires then?
when you back into a camp spot with shore power, isnt the power usually on the side opposite where the power cord comes out of the side of the scamp?
That Mighty Mini is sort of different beast in that it is an entire electrical
panel in one device. I have tended more toward the dedicated device approach. AC load center for AC, Converter as load center for 12 volt. That disclaimer out of the way.
Amps required depend on how much draw your gadgets and equipment will draw. I don't know the capacity people find necessary but the stock converter from scamp in the online store is 30 amp.
Under front bunk is a good location for much of this stuff. Converter becomes "source" for all your existing 12 volt system and those existing feed lines come in from the front you don't cut n cap you tie them into converter. If you put converter under bunk or under sink either way existing wires to system and battery tie into converter.
In effect the converter sits on the circuit between battery and rest of trailer and either gets power for trailer 12 volt from battery or supplies 12 volt power when plugged into shore power. It is an electric switch of sorts that switches to it's internal transformer as source for 12 volt when it gets 110 current from shore power. Or back to battery as source when 110 is not available.
Converter at the minimum just needs a 110 line run to it. As others have mentioned it can also function as your 110 AC load center too. But does not have to. You can treat it as just 12 volt converter OR as an AC sub panel such as one might have out in a shop at home. Sort of depends on how much wire you want to run.
Your rainbow of wires if 12 volt would need to be run to one of the fused circuits of the charge controller. Or if rainbow wire is 110 you can pick if you want to connect to existing 110 load center or run new wires to 110 circuit of converter.
Charge controller for solar is another device that would work well in this front storage location as would a 12 volt to 110 inverter if you ever decide to have a 110 plug that draws from the battery. Inverters work better if they have a nice short length of really heavy gauge wire to the battery. And I think solar charge controller to battery connection benefits from short heavy wire also.
