We use all SI units totally, so joules, watts, etcetc, its much simpler to go from joules to watts. When i did the dyno work of course we only work in NM and Kw, all appliances and HVAC units are rated in Kw. I only have single phase power at my home, but the feed in fuses are rated at 100a, so there is plenty available. My previous home in Western Australia had a 3 phase feed to serve a large A?C unit that was ducted to do the whole home. It also had a 3 phase bore pump for the lawns. Most modern homes here only have single phase. I have a 4kw solar system split into two sets of panels on facing ne, and one sw, I have seen 5kw from this on a couple of occasions, but generally i get 2.5 or so. Ive averaged 10kw/h per day over the 8 years its been installed. About 27% of homes in Australia have rooftop solar, one of the worlds highest per capita uptakes, and rising quite rapidly now that power is in the range of 40c/kwh. Some outback towns have diesel fired generators still, but thats soon to go fully renewables. We have gone far of the original track, I hope thats Ok, its interesting stuff IMO.
