to charge a 48 volt battery pack you need to get them up to 60 volts to equalize the batteries and my parents system is 24 volts altho the panels are wired to 72 volts with a maximum power point charge controller that drops it to 24v right before the batteries so they could use smaller wire under ground, it also allowed them to get more total watts out of the array.
