There is a small step (between the modified and the true sine wave): The PMW sine wave ( the UPS usually use that voltage). I was thinking, and its more simply than i thought. If you send your energy to the distributor grid. The power metter will go back so its the same as you use that energy with your loads. The hibrid system has no sense.

Your inverter burns because the current from the GTI was accumulated in ther internal capacitor (of the inverter). The increasing current produces a increasing voltage (in the capacitor) until it blows up.

I think the key is the inverter that ddepvil1 uses (Xantrex XPower 3000) that doesnt allows that the current goes inside. I know that system has a load detector, when there is no load the inverter turns off. Weve get to open one of that and see what is in there

Maybe a diode (in the DC line) is the solution..maybe.
