In today’s video, we build the uprights to support the second set of solar panels. Next, we lay out those three panels and do all the work of mounting them together. https://300mpg.org/solar-trailer/
Please click SHOW MORE!
Just like the first side of the trailer, the solar panels are supported by a pair of 1.5"x3" c-channel pieces of steel, about three feet long. Welded on top of that is a plate that holds a bearing, which will hold the end of the panels and allow them to rotate. The uprights are a little over 10 feet apart from each other.
The solar panels on this side are mounted to a 10 foot long piece of 2-inch diameter black gas pipe. To actually hold the panels to the pipe, I use three foot long pieces of 3" wide flat steel and 2.25" automotive exhaust clamps.
This project is a bit of an experiment in building a portable, off-grid solar system using mostly what I already have. The Charge Controller is one that I’ve already had for years. The battery is made from 7 Nissan Leaf Cell modules. See the video on building the battery at: https://www.youtube.com/watch?v=juk39…
The inverter is a repurposed Uninterruptable Power Supply (UPS) which ran on 48V and would have originally been used in a computer server room. I’m just using the inverter portion of this unit, but it could also be used as a battery charger if I connected it to wall AC power. I used this same unit to power my house during a blackout from my motorcycle. Learn more about that at: https://www.youtube.com/watch?v=-ydKi…
