The battery is just a 12 volt car battery you can pick up for free and desulfate (per my ebooks such as windmill or welding). With a solar panel less than 10 watts, you won't need a charge controller. You will have to place the inverter at the bottom of the box and make sure that the box is vented with small holes at the top. This is due to the corrosive gasses that come off the battery when charging or draining. Don't put big holes because birds will make it their home. You can also encase the inverter in it's own section with vent holes. All the vent holes should have a mesh or screen on the inside to keep bugs out as well. And make sure that rain can't get in. The handles are just pieces of rope put through holes and knots tied on the inside.
