Solar Powered RV
Is there a way to run the Motorhome with solar panels (especially the A/C and microwave)? If so, how much do I need?

Hi mts,
You won't need as many batteries given the size of solar system. I would size the system based on 1.5 X the wattage of the air conditioner, so about 1800 watts.
That means that during the hottest part of the day the batteries will charge and the panels will directly run the air conditioner.
The panels could be on the roof in two layers. One that is fixed, and one that slides and then tilts to the optimum angle.
Battery system voltage at 48 means just a single controller is needed for 1800 watts. 12 volt needs could be from an ordinary converter such as a 55 amp PD unit with a single 12 volt battery as a "cushion".
Because, for most of the day, the panels will provide all power, the battery bank need not be quite so massive. Mena's bank, or mine might be large enough, if they were rewired for 48 volts.
