Grid Tie Inverters

There are quite a few reasonably priced grid tie inverters now appearing especially on e-bay and of course from china.

Now I have two wind turbines dumping into some old TS lithium cells for my garage use, but the idea of putting that into the house via a grid tie inverter is appealing.

What happens if you have a battery buffer between turbine and inverter and why is this discouraged? If you feed one of these inverters via an unrestricted power source (battery) within it's voltage rating what happens. I note they have a wide input voltage range.

Who says a battery buffer is 'discouraged', Peter?

I don't know much about this technology, but would have thought extra storage anywhere was a good idea.

Maybe you have to set the maximum current the inverter can take from the battery, to stop it all disappearing in one go?

I have read a little bit about Vehicle-to-Grid systems which would do exactly what you are suggesting.
