Not the poster, but I live off-grid on a boat in the UK and pretty much everything (including the laptop I'm commenting from) runs off 12V DC.
I have 800W of solar panels and a 3.5kWh LFP battery bank.
I use approximately 2kWh per day in summer, 1kWh in winter, 500Wh when it's cold enough that I can turn the fridge off.
In the summer I dump any excess to an immersion water heater.
At that level the self-consumption power of an inverter, about 5-10W, is significant so I avoid relying on it for anything powered all day (but it's useful for appliances, power tools and other intermittent items).
Using incredibly wasteful amounts of energy isn't necessary, people just do it.
