Phase 1 of this story which includes motivation, requirements and initial progress is located at this link:
This phase will focus on the solarization of the trailer. I will save you any suspense and show you what that looks like after many hours of testing and attaching of the solar panels.
|Trailer with about 240 watts of PV panels attached.|
I set the panels out on the grass and started testing their amperage and voltages in an attempt to figure out the safest, most cost effective way to charge the battery on the e-trike. You see, that battery is very expensive. For me, these days a DC charge controllers' goal is to make sure the battery is charged safely, cost effectively, and doesn't damage the value of the expensive battery.

|Testing of DC charge controller suitable for voltages and amps of surplus PV modules.|
During this testing the walls were off the trailer and I noticed that the size of the trike made it perfect for inside the trailer. Don't know the circumstances when I would need such knowledge, but that is one of the features of knowledge, right?
|E-Trike inside trailer.|
I mounted the charge controller on a permanent wall at the front of the e-trailer.

|Inside of trailer has a carpet.|

The next to phases of this e-trailer build are to make a tiny kitchen front bulb out, make a back fairing with storage (similar to this blog), and make an aerodynamic space rocket that fits to the top, all made out of very light weight materials (possibly coroplast). Stay tuned, and don't hesitate to e-mail me with questions, comments or encouragement. email@example.com Thanks for reading.
