I have been asked to come up with a solution to solar charge an 36V battery bank.
Current setup:
3 x Victron (110Ah) BAT412101084 Connected in series to provide 36V
the charger is a Pro Sport 20 Plus (mains powered charging 3 batteries individually 12v)
What I like to do is install 3 solar panels 12V, each connected with a SmartSolar charge controller MPPT 75/10 (12V). So each unit will charge each battery individually (like the current installed charger)
My questions:
Would there be an advance/disadvantage in connecting the panels in series and connect a MPPT 150/35 in a 36V setup and charge all batteries in one go?
Will the 12V setup be powerful enough to charge the 12v Victron 110ah batteries
