I recently purchased a piece of mountain land, and after considering everything from an RV to Cobb, I have finally decided to convert a school bus. I have not yet purchased a bus, but I have a fairly good idea of what I want. My first question is if anyone has any experience with a complete off grid solar system? I do have the option of running grid electric to my property, but I think a 48V solar system would be best. I recently found a 48V DC heat/air system that I think would be a great thing, although I definitely will be supplementing with wood in the winter. The problem is that the unit requires 16 batteries. If I buy a 72 - 84 passenger rear engine bus, will that give me enough space under the bus for storage? I will need additional batteries also for lights, refrigerator, TV etc. But the heat/ac will be the biggest draw on the system. Does anyone have any ideas? This system is for up to 24/7 use on the heat/ac and refrigerator. I have Chihuahua's so they can't get too hot or cold. Here is the link to the system, the 20/24 heavy duty system: Solar DC Air Conditioning Systems
