I would like to build a system in a converted cargo trailer to camper that is capable of running a 120v 1300 watt ac unit, a single cup 120v coffee, 6-12v led lights inside and 4-12v led lights outside, with shore power and a 2000 watt generator when no shore power is available. I am in the process of purchasing a trailer with 400 watts of solar panels on the roof now. I am not sure what comes with it other than the panels. I am assuming nothing. Help and advice will be GREATLY APPRECIATED.
