boondock and have your fridge/ac/micro

The first thing is to realize and accept the fact that using the AC off the batteries is not a reasonable expectation. The battery bank would be far too heavy for a fifth-wheel to be able to run the air conditioner for any significant amount of time. I'd even be very conservative about using the microwave. But the MV is used for short periods of time. If the AC is needed it would be run continuously.

It is the refrigerator which would be a large factor in determining the capacity of the battery bank. (my opinions)

Absolutely agree, i just did my math and i would need close to 800Ah to run the domestic fridge and some other appliances and allow for 50% discharge on batteries between the charges (daily) from geny as i dont think solar is capable to do this alone.

Check out my cousin's husband's bus rebuild at http://www.beginningfromthismorning.com/. They're going with a 98% electric configuration, with propane only used for the water heater. Electrics come from 3500 watts of solar and 3200+ Amp hours of battery storage. Battery is from a Nissan Leaf, plus one extra module to provide the proper voltage. He gives excellent details on everything they're doing. Last project was a complete new dash with an added tach and a GPS-enabled speedometer! :B

I love the idea using electric car battery :-)

for now i am looking at 4x 200Ah Li-ion battery, but they are bloody expensive, but will see it will all depend on the rig we get on the end :-)
