hallo, I have a question that I look up on the internet and nothing gives me direct answer.
anyway, when we have a battery charger from solar panels and work on MPPT, how does it exactly work? I saw datasheet for some of 12V system solar panels and it says most of the time Vmp is about 18-17 volt but to charge batteries I need 13-14 volt only. so how I can charge batteries and still do MPPT? I need two DC-DC converters? like one for MPPT and another one for charging a battery and include BMS "battery management system"? but honestly it does not make sense to me to have two DC-DC converters, so if anyone gives me to answer or give me any pdf or Matlab file to see how it could work?
