How can I use an IC family or adapter to switch automatically from solar cell to batteries & reverse ?
if no load => solar cells charges the batteries
if there is a load then if p2 > p1 then trigger makes comparator connects load power from CELL else (p1 > p2) then trigger makes comparator connects load power from batteries else CELLS charges the batteries fi fi
Is there some specialized IC to manage something like this as "comparator" is this a bad approach of the need? (and then if you have ideas please provides them).
This is not really similar to : this question ...
