Phase 1 of this story which includes motivation, requirements and initial progress is located at this link:
This phase will focus on the
|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 the trailer.|
I mounted the charge controller on a permanent wall at the front of the e-trailer.

This update includes a photo from when I exhibited at the tiny house show held at the US Air Force Academy last year.

A more recent version puts two of the PV panels permanently onto the top of the trailer.

48 volts and about 160 watts of power for driving the hub motor on the recumbent trike. PV panels are flat when moving.
