Grid tie micro inverter powered by battery !

In this video i will demonstrate that under given conditions it is possible to use grid tie micro inverter with battery instead of solar panel.. and even more, i will show that it is possible to use many in parallel to increase your DC-AC power conversion.
Please be advised that no inverter was connected to the grid. the grid was simulated with an 5kVA inverter under load and powered with independent battery.
In other words, that is a totally independent system with nothing connected to the house or to the grid. I could have done this demo in the middle of the desert and it would have worked =)
