I wanted you to have alook before I wire it up on Kicad as at the moment I'm not sure if I've got it right and some connections seem wrong
e.g the connections out of the board that is in series have been connected together on the pcb - by KICAD - do I need to change it in the schematic or can I do that in the wiring?

Questions
How big is the Renewable charger PCB?
It measures 148.2 × 34.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Renewable charger use?
45 parts, built around the CN3791. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Renewable charger KiCad files?
From the Tactile-electronics/windmill-electronics repository on GitHub, at the commit this page was made from: the board is renewable-charger/renewable-charger.kicad_pcb and its schematic renewable-charger/renewable-charger.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Renewable charger design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
