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.).

Projets existants

Interesting building blocks

Notes

Diviseur de tension.

R1=98.4 kohm
R2=46.2 kohm
H = R2/(R1+R2) = 0.320
Vinmax = 5 / H = 15.6
