Develop 3D Product Design for Electrification Device

We are developing a low-cost, smart power sharing device for emerging markets. We need a 3D rendering of what our product looks like and have attached a preliminary SolidWorks drawing. Basically, the box is can take in multiple electricity generation sources (i.e. solar panels, diesel generators), and connect to multiple loads (i.e. cell phones, simple CFL lights). The box is also connected to the electricity grid through wires. We are looking for a few things to be added to our current drawing. 1.) Add in some loads that are plugged into the box (i.e. a cell phone and a simple light that are plugged into the box through wires). 2.) Add in a generating source. For now, we would like this to be a solar panel, connected to the box and sitting in the background of the image. 3.) Make the box look sleeker. Something that looks sophisticated (perhaps something similar in size and shape to an Apple TV box). If this is successful, we have another task that we would like completed as well.
