AMEN! We need to be careful about using the term MPPT. MPPT in a solar grid-tie inverter will MAXIMIZE power from the source (solar panels) and dump it all in the infinite grid. Putting a battery in place of solar panels will do the same thing. It will MAXIMALLY load the battery and shove everything it can into the grid. (this makes no sense to any practical use)
And when the grid goes down, it shuts down, again, of no practical value to anyone. The only exception is a MPPT Grid-Tie inverter that ALSO has in internal switch over from grid-tie to a "secure power outlet" like the SMA inverters. But then it is no longer operating like an MPPT inverter and acts like a simple $99 1500 Watt battery inverter. MPPT is also used to describe solar battery chargers to maximize the battery charging from whatever sun is available, But this is a totally different application and has nothing to do with feeding a load.
