I think that what he means is that by switching to a 48V battery you can 
have (add)
twice as much array  power rating than you can get from a 24V battery bank,
at a given battery output current.   1500 Watt max array for a 60 Amp 
controller and
24 Volts or  3000 Watts for a 60 Amp controller and 48 Volts.

Or, 4 times the array size if you compare to a 12V battery system by 
going to 48 Volts.
