First post from a novice. Need some advice by someone who can give me some guidance and best solution. Still confused how to think in a broader picture and what is best method.
I will be using 4 flexible panels, 160watt each (Vmpp: 20,52 V, Impp: 7,8 A)
I have to charge 2 separate battery banks, one is 12v 100AH and the other 24v 200AH. When weather permits I will run a bldc 24volt motor directly from panels and not the 24v bank.
So logic say I need at least 2 separate controllers (MPPT), one for the 12v and one for the 24v bank. Or maybe there is somekind of controller that can handle 2 banks?
If I connect all panels in parallel it will not work because I think the 24 volt will not charge and I can not run the bldc motor directly on sun.
Is using a dc2dc bridge something I can consider? Then I can use one bridge for the 24v bank and one bridge for the bldc motor?
Is this an option?
I could use one panel for the 12v but then its "idle" and useless when 12v is full making it not optimal.
What is the best method to achieve what I want?
