Hi all, I've just watched a video about the problems of back-feeding your home with an inverter/battery source, most of which relate to the split-phase system in the US. It got me thinking about the differences between this and the UK (and EU) mains supply, which is single-phase 230V. This seems better because: 1. Simpler wiring in and up to the home 2. Smaller wires (cheaper) 3. High-power appliances, like our standard 3 kW kettle and 2.6 kW vacuum cleaner, can be plugged in anywhere without needing (as I understand it) a special double-tap arrangement. Other than greater safety from lower voltage, is there an advantage to the US system that I can't see? Or is the system there for historical reasons and there'd be too much upheaval to change it? I wouldn't be surprised if it's the latter; there are PLENTY of systems in the UK that fall under this heading.
