I'm trying to create a little solar charger with backup battery for my Arduino. I would like to use a MPPT controller for the solar panels. I found a few solutions like the IC CN3722, but all of these solutions need a battery (or have too many functions to monitor a battery charge). Because I want to use a few 18650 Li-Ion batteries I would use a battery management system.
Are there MPPT IC's that have a direct load output which I can use as input for my BMS?
I'm sorry for these newbie question but I searched the whole week and didn't find anything.
