I don't know about 48 volts, but 24 volt lighting and motors are
plenty common in our house, and not more expensive than 12 volt.
But most modern RE homes are using primarily AC, and inverters are
readily available in 24 volt and 48 volt configurations.

Big currents at low voltages take big wires to avoid losses.\
