I had a solar charger, but wit the years the complex electronics supporting it gave up. But when I took it apart I noticed that the panels them selfs were still working. Wanting to reuse them I came up with this. A programmable solar charger.
by a simple shorting block and headers you can 'program' it so the output is:
- only from a single panel (left or right)
- the solar cells are in series
- the solar cells are in parallel.
I will try to explain here how you can make this yourself.
