Fun stuff. I've built several systems just like this one for camping, they let you keep things like iPads or laptops charged and they aren't noisy like running a generator.

Something that my wife discovered was that an igloo "lunchmate" cooler was perfect to hold the battery and charge controller. Makes it easy to carry. I recommend using Anderson Powerpole connectors (https://powerwerx.com/anderson-power-powerpole-sb-connectors) to make it easy to set up and tear down. I typically use one pair of colors for the connections to the battery, and another pair of colors for the panel to charge controller.
