Yeah I feel like this is very tractable problem. Most of my stuff runs on USB-C anyways, I just need USB power outlets everywhere. My lights, motor blinds, bathroom fans can run on POE, including data. My oven should already have its own battery installed, or a capacitor bank for very fast preheat. My fridge can do the same. It’s rarely actually compressing. I’m mostly just trying to avoid needing to buy very expensive inverters.

Those types of appliances are coming: Induction stoves with batteries built in, and why they matter A conversation with Sam Calisch of Channing Street Copper Company and Wyatt Merrill of DOE. https://www.volts.wtf/p/induction-stoves-with-batteries-built https://www.volts.wtf/p/induction-stoves-with-batteries-buil...

  And so we come full circle. Using a DC battery to power an inherently AC induction process. These are not your mother's home appliances.

  Induction DC stove tops are also popular for off the grid cooking…when you just have solar panels and a car battery.

USB is too low a voltage to be useful. You will always need an adaptor to get from mains voltage to something useful for devices. There is nothing wrong with AC for mains, and the ease of transformers is not to be ignored. Current voltage AC is still ideal for powering a house '

  If USB PD were used, you would have up to 48V (240W) available, which should cover all but the largest appliances.

    48 volts is not enough to cover a house without very large and expensive wires. And you still need to get higher voltage from the street to the house.

  Their secret is variable speed compressors, advertised as "Inverter technology". The compressor run continuously, it just changes speed so there is no noisy and inefficient start-up surge current. Also common in heat=pumps, Air-conditioners, etc.
