[null and void]

This is not a true sine wave inverter. True sine wave inverters (often called synchronous inverters) are required for a utility grid tie in and run at far less efficiency than the unit you cite. Inverters running at the level of efficiency you referenced, are designed with switching power supplies that include heavy amounts of low pass filtering in order to simulate (but never actually achieve) a sine wave output. They are not capable of being tied to the utility grid, and either run as "stand alones" or tied only to a local power grid.

OH MY GOD!!! Some call PG&E and let them know!!! I've been tied to their grid for about 3 years!!!

Would this be in the same way that you were getting 800 watts out of a 2m^2 solar array???

What are you trying to say? Are you saying you are tied to the public utility grid with an AEI GC-1000? When your PV array is making more power than you can use, is your excess (and only your excess) put out onto the utility power grid for other to use? When you use more power than the PV array can supply, does the utility makes up the difference (and only the difference)? If your answer is no to any of these then you need to re-think your last reply.

I'll grant you that, despite having relatively high levels of THD, the inverter models you both referenced are in the 90% efficiency range and are qualified to be connected to the utility grid as synchronous inverters. However, that changes this thread premise and conclusions by "mouse nuts".
