Solar Build Day1

I'll probably update the title at some point but for now... I am building a test setup for an off-grid camping trip. A bit out of the ordinary campout. I have rented a screened in cabin and will be spending a week there. I am an amateur radio operator (callsign KN2Z) so I will be doing a lot of radio communications while I'm there. So, I have radios, computers (laptops), a small 12 volt cooler, some medical equipment.. all requiring a supply of power. Here's the setup I'm putting together for now.
