DIY Solar-Powered Shipping Container Ventilation

Building an off-grid solar powered shipping container ventilation system. I had a problem with condensation inside the container and I'm hoping that this will be the solution (update: it works!) I hope this helps you out. Let me know! Here are the components that I used for the project: Renogy 50w Solar Panel: https://amzn.to/4a9tljA 12v Radiator Fan: https://amzn.to/3VvPSmb 2-way Switch(NOTE: I had the original switch fail on me. I hardwired the panel to the radiator fan. I've included another well-reviewed latching polarity reverse switch, if you need one -- Thanks to the viewer that pointed out that I had linked a momentary switch): https://amzn.to/4eIzl4z Solar Panel Mounting Bracket: https://amzn.to/3VxccvA Automotive Fuse Holders and Fuses: https://amzn.to/43vgKo8 Rare-earth Mounting Magnets: https://amzn.to/497Qlhs Grommets: https://amzn.to/3vruW5a
