Yeah but won't the system benefit from achieving faster charge in a shorter space of time, i.e if you have a two 12/24Vdc 40A Mppt controller feed by the same PV array for a 12/24Vdc bank either connected in P/S as to just one controller?
Can more than one charge controllers be connected to a single PV array to charge more than one battery bank or to the same battery bank to maximize charging? if not why?
