Direct Current in the home

PeterRT

With more and more in the home being powered off DC (Direct Current) supplies, e.g. Battery & Solar Panels, then wouldn't it be more economical to consider extending the regulations to cover DC in the home avoiding the need for transformers?

For example, this is particularly appropriate now that lighting is dominated by LED.

    At least the preferred voltages do not include 8 volts, 16 volts or 32 volts all of which must be nearly extinct now.

    The 28 volts used on many aircraft is I believe obtained from a 24 volt nominal battery, 12 lead acid cells. Should be about 28 volts in flight as battery on float charge.

    The older BR era diesel locomotives were often said to use “110 volts” . This was a 96 volt nominal lead acid battery, 48 cells. averaged about 110 volts on charge.
