[[Category:Proposed_ProjectsOngoing_Projects]] == 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.).
