To drive the grid, your inverter has to synchronize with the grid, not only matching the frequency but running exactly in phase. There are "grid-tie" inverters that can do this automatically, but they aren't cheap. A grid-tie inverter also has to either shut down or disconnect if the grid fails, to avoid electrocuting some lineman working on a stretch of line that he thinks is dead. To be worth the expense of a grid-tie system, you'd need a *lot* more than a window-sized PV array. No, and inverter makes AC from DC; a rectifier converts AC to DC.

Glad this is sparking conversation. I don't pretend to know it all, and had my skepticism about this as well. Given that, I think anything that can make it easier to get solar, by a little or a lot, is something to be encouraged. Got questions about it, want to help make it even better? Write the CEO, capra@verandasolar.com Nice! Glad this is sparking conversation. I don’t pretend to know it all, and had my skepticism about this as well.

The utility may be required to approve of certain installations and buy back your power. I'm glad that it's easy in Portland. And folks are doing the work of convincing utility regulators to make it more common that folks can feed power into the grid. http://www.greentechmedia.com/articles/gainesville-to-launch-solar-feed-in-tariff-5429.html Actually, the law does vary by where you live.

If you have more current than you need coming into your house, it will be bought by your utility company, and your electric meter will run backward, this have nothiung to do with invertors. Nops, match AC? You need a recttifier to convert DC into AC, Match? you don't know what you are taliking about. Invertor convert AC to DC period.

So, that runs your meter backwards, then? I presume this can only work if your utility allows for it right? @sturmey – that’s excellent, thanks! So, that runs your meter backwards, then?

They match the AC waveform and feed current back through you house lines. all you do is set up a solar panel or windmill, connect to the invertor and plg the invertor into the wall.

There's no way you can just pump power back into them. Not only that, but solar panels put out DC power. You need an inverter. Maybe this thing could power a radio or something that you plug into an inverter. But I guarantee you can't just plug it into the wall. You might need to do some extra homework on this one.

Someone answered in Portland that when you have duplex style outlets, power can go both ways. Apparently this is standard in many places. Electricians, can you confirm this? @Dave: That’s what I thought too, until I asked on Twitter. Someone answered in Portland that when you have duplex style outlets, power can go both ways.
