I just ordered a kit on amazon that came with the panels and charge controller and everything to hook up to a battery. I already had the inverter. I had to make some cables to connect the batteries in parallel with 8 awg after my brother bought 4 lithium deep cycle batteries. It was pretty easy to figure out. 

I still need to hook up the cigarette lighter/ USB thingy sold for boats. I may get a fuse box to do this.
