I realized a solar battery charger circuit based on LT3652. Actually it doesn't work well, but I think I made some project error. In fact it doesn't reach the end of charge status. But first of all I need some theoretic suggestions.
Panel: Voc = 20V; Vp = 16.5V; P = 5W; Ip = 0.31A;
Battery: Lead-Acid; 12V; C = 4Ah;
The questions are:
What is the maximum charging current reachable? Icharge < Ipeak * (efficiency *Vpanel ) / Vbat is correct?
What happens if I set a charging current too high, for example 1A?
