Hi All, a quick update from our 3 phase solar grid / storage hybrid system (first time ever attempted in Australia). The entire property is now being supplied from the solar systems, the batteries are charging from the solar systems, NO GRID POWER IS BEING USED.... We replicated a battery failure or battery depleted scenario and the system completed an un-interrupted seamless transfer of power back to grid without even a glitch in the supply. We then turned the battery system back on and the transfer back to off grid and solar generation and battery supply occurred again without any interruption to supply. A true grid hybrid storage and backup system is now in place.
We need to program the system to now feed excess energy back into the grid so not alone will the system be independent from the grid, we will actually generate a credit, and I will post an update when this is completed.
