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.

    I think the authors of the current regs BS7671 think they do already cover the  use of LV and ELV DC in the home, with a nod to other standards for things like telecom equipment.

    Solar panel strings of less than 1kV are covered, as are SELV and PELV DC systems.

     I suspect what you are really wishing for is for someone to decree a standard voltage and or harmonised set of connectors, and sadly that is as far off as ever it was.
