inverter

Placing an inverter in the loop is probably cheaper and more efficient than routing 12V electricity though one's house.

Rooftop solar has really taken off here in Australia, and around 20-25% of houses have a solar inverter.

By inverter, do you mean DC to AC conversion?

Is it practical to build a cheap rooftop wind-power harvester that plugs into the inverter?

Dave's 3kW system apparently cost $5k (Australian) and that included the inverter and decent panels.

Not counting inefficiencies in the battery, inefficiencies in the inverter or installation costs.

I have a batch of Positive Karma Inverter devices, do you want to buy some?

It was powered through an inverter by our car's cigarette lighter.

There are also some safety concerns in having both a battery pack and an inverter (altough a low voltage one) sitting in your house now.

This headline number is not the total cost of course, you need charge controller, inverter, building to house the batteries, etc.

It's quite likely your friend uses a generator or inverter.

Rumor is the DC -> AC inverter is built in.

If you want to investigate further, the key is to include the keyword "inverter", which is how Panasonic advertises it.

My parents in Australia just paid $10k AUD for 5KW fully installed including the inverter and "smart meter".

It is called a "grid tie" power inverter, commonly used with solar panels.

Also the circuit topology is the same either way (but for the inverter on the clock), just the circuit "works" for different reasons, and thus the timing is different.] I don't quite know what you are asking, but I think/hope the answer is yes.

Solar panels are far worse but even there the payback time for the complete System (Panel, Inverter, Installation, Transport) is between 2.5 Years to 1 Year depending on the panel technology [1].
