Code
Le code Arduino a été publié sur github:
https://github.com/ctrlaltdel/PaleoSolarCharger
Objectif
Développer un dispositif de gestion de charge de batteries. Ce système devra gérer plusieurs producteurs (panneaux solaires, éolienne, génératrice, etc.) ainsi que plusieurs consommateurs (éclairage, pompes de circulation, convertisseur 12V/220V, etc.).

Interesting building blocks
Notes
R1=98.4 kohm R2=46.2 kohm H = R2/(R1+R2) = 0.320 Vinmax = 5 / H = 15.6
