Electric - Run my house off my Tesla

You're confusing two different units. kW and kWh aren't the same.

The other thing that you need to think about is power output. A single Powerwall 2 will output at a maximum of 5kW: enough to run an oven but not an oven and kettle at the same time.

Just looked at my power for yesterday - highest was 0.74 kWh over a 30 min period, two other half hour periods around 0.65 kWh and all other times below 0.35 kWh (midnight to 5am less than 0.05 kWh per 30 min segment)

It's not the 30-minute average that causes problems, it's the spikes.

To have a maximum load of 740W would mean you don't have a kettle, a toaster, a microwave - or any sort of electrical cooking / heating appliance beyond an electric blanket.

Thanks - I was sat scratching my head as the figures were low - brain didn't click that it was overall consumption not allowing for peaks duh lol

You wouldn't want powerwalls they are still too expensive per kwh.
