Their total household usage was actually ~17.3 MWh depending on what data source you're using for their usage.

Given 6 MWh of exports with only 3.2 MWh of total solar production, they are cycling their powerwall to get paid for the fact that their off-peak rate is half the price of their peak export tariff rate which is inflating the number you're looking at.

That is still an enormous amount of electricity for a single family to consume.

Sorta, kinda, it depends.

In my house I only run LED lighting and an occasional oven, some phones and laptops, a cycling fridge and two weekly wash cycles, in other words, virtually no electricity. I'm at like 2 kWh per day.

The ~45 kWh a day for this family is gigantic compared to mine, like >20 of my homes in one.

But I don't have an electric car, nor electric heating or cooling, nor an electric stove.

If you have say a standard electric car like a Peugeot 208 which uses 15 kWh per 100km, and you both drive one hour (say 60km) to work and back, five days a week, that's already 25 kWh per day.

My heating bill (gas, europe) is an order of magnitude of my electric bill. Even if I'd electrify it (cheaper), it'd likely be an additional 10 kWh per day.

If you have slightly more fancy lifestyle (they run home-servers and a hottub for example), you can easily get to 45 kWh.

I think the fair comparison is to look at a household total energy expenditure (energy & $). My household has a low electrical share, theirs has an almost exclusive electrical share.

He mentions that he has a server. It wouldn't surprise me if that consumes the majority of that.

It's less than 50kwh a day, high but seems reasonable with 2 electric cars.
