There have been two previous posts on this project: one on the concept and the hardware and one on hardware testing. You probably want to check them out first if you’re not yet familiar with this project. Or even better: Click here for an overview over this project.
First tests are being performed on the Solar Charger Shield In my last post I’ve introduced a proof-of-concept Arduino solar charger shield. I went through the hardware as well as the way it works - or at least is intended to work. It was prominently linked on dangerousprototypes.com as well as some other sites and got quite a bit of publicity as a result. Thank you all for sharing this post.
A friend has approached me regarding his solar project. He wants to install a solar panel together with a battery and an inverter in order to have power at his allotment garden. He had looked at a hobbyist project where an arduino was used to build a MPPT (maximum point of power tracking) charge controller. I took a look at the design, liked a lot of what I saw and decided to build something similar.
