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 mena,
I just checked the Dometic pdf. The 13500 draws 12.4 amps plus 3 amps for the fan. Locked rotor is 63 amps. The 15000 draws 13.3 amps plus 2.8 amps for the fan with locked rotor at 66 amps. My air conditioner is a Dometic from 2004 and is 13500 btu's. I was comparing apples to apples with the about the same cooling capacity. I do admit the 1200 came from measurements of my own unit.
(drat this is making me "rethink" the size of inverter I need :( )
Last time I check 60 x 3 = 180 amps? (typo yes?) but I agree 2 x 9 = 18 = 25% more cooling for the same amps.

You keep thinking everyone has YOUR A/C unit when most everyone has a standard 13.5k or 15k BTU unit and the 13.5k's draw about 120 amps and the 15k's draw 150 amps. With a standard 15k unit, there would be a 50 amp savings.
They have a rooftop 9k unit that draws 720W in either 12 or 24V. Say it's 12V, that's 60A. Three of those would provide 27k of cooling and draw as much as ONE 13.5k unit.
