Thanks for the links you have sent to me.
It is a lot to read and very interesting.
I would like to submit a concept for having reply and discussion:
All the documentation talks about the peaking of the PV power output by control the V*I product at its maximum possible level.
What do you think if the program will adjust the dc_dc duty cycle just to peak the battery current at max level ? The target is to inject the max possible current in the battery for recharging and so, why do not try to get it at its maximum ?
Thanks
Ambrogio
