I am putting together a 48v off grid system. During the winter the 48v bank will be maintained by a Conext XW 60 MTTP charge controller (I don't want the inverter on when I'm not there so it will be powered down). I would like to maintain my 12v bank on my travel trailer over the winter. The 12v bank won't have any loads on it and the only load on the 48v system will be the CC for the 12v bank.
I have read the Morningstar MTTP charge controller is able to do what I want. However, I have a Windynation 30a PWM controller that can accept a VOC of 55 volts. Can I use this PWM controller connected to the 48v bank to charge the 12v bank? If an MTTP CC will work why wouldn't a PWM CC (assuming it can handle the voltage).
Thanks for any advice.
